Mind the Gap! The Leap from Legacy to Modern Applications 

Legacy to Modern Applications | modernizing legacy applications

Most businesses today have evaluated their options for application modernization. Planned movement to the cloud happened ahead of schedule, driven by the need for rapid scalability and agility in the wake of COVID-19.

Legacy applications already rehosted or replatformed in the cloud saw increased load, highlighting painful inefficiencies in scalability and sometimes even causing outages. Your business has likely already taken some first steps in app modernization and updating legacy systems. 

Of the seven options to modernize with legacy systems outlined by Gartner, 2nd Watch commonly works with clients who have already successfully rehosted and replatformed applications. To a lesser extent, we see mainframe applications encapsulated in a modern RESTful API or replaced altogether. Businesses frequently take those first steps in their digital transformation but find themselves stuck crossing the gap to a fully modern application. 

What are common issues and solutions businesses face as they move away from outdated technologies and progress towards fully modern applications? 

Keeping the Goal in Mind 

Overcoming the inertia to begin a modernization project is often a lengthy process, requiring several months or as much as a year or more to complete the first phases. Development teams require training, thorough and careful planning must occur, and unforeseen challenges are encountered and overcome. Through it all, the needs of the business never slow down, and the temptation to halt or dramatically slow legacy modernization efforts after the initial phases of modernization can be substantial. 

No matter what the end state of the modernization journey looks like, it can be helpful to keep it at the forefront of the development team’s minds. In today’s remote and hybrid working environment, that’s not as easy as keeping a whiteboard or poster in a room. Sprint ceremonies should include a brief reminder of long-term business goals, especially for backlog or sprint reviews. Keep the team invested in the business and technical reasons and the question “why modernize legacy applications” at the forefront of their minds. Most importantly, solicit their feedback on the process required to accomplish the long-term strategic goals of the business. 

With the goal firmly in your development team’s minds, it’s time to tackle tactics in migrating from legacy apps to newer systems. What are some of these common stumbling blocks on the road to refactoring and rearchitecting legacy software?

Refactoring 

Refactoring an application can encompass a broad set of areas. Refactoring is sometimes as straightforward as reducing technical debt, or it can be as complex as breaking apart a monolithic application into smaller services. In 2nd Watch’s experience, some common issues when refactoring running applications include: 

  • Limited knowledge of cloud-based architectural patterns.
    Even common architectures like 2- and 3-tier applications require some legacy code changes when an application has moved from a data center to a cloud service provider or among cloud service providers. Where an older application may have hardcoded IP addresses or DNS, a modern approach to accessing application tiers would use environment variables configured at runtime, pointing at load balancers. 
  • Lack of telemetry and observability.
    Development teams are frequently hesitant to make changes quickly because there are too many unknowns in their application. Proper monitoring of known unknowns (metrics) and unknown unknowns (observability) can demystify the impact of refactoring. For more context around the types of unknowns and how to work with them in an application, Charity Majors frequently writes on the topic. 
  • Lack of thorough automated tests.
    A lack of automated tests also slows the ability to make changes because developers cannot anticipate what their changes might break. Improved telemetry and observability can help, but automated testing is the other side of the equation. Tools like Codecov can initially help improve test coverage, but unless carefully attended, incentivizing a percentage of test coverage across the codebase can lead to tests that do not thoroughly cover all common use cases. Good unit tests and integration testing can halt problems before they even start. 
  • No blueprint for optimal refactoring.
    Without a clear blueprint for understanding what an optimally refactored app looks like, development and information technology teams can become frustrated or unclear about their end goals. Heroku’s Twelve-Factor App methodology is one commonly used framework for crafting or refactoring modern applications. It has the added benefit of being applicable to many deployment models – single- or multiple-server, containers, or serverless. 

Rearchitecting Rearchitecting an application

Rearchitecting an application to leverage better capabilities, such as those found in a cloud service provider’s Platform-as-a-Service (PaaS) or Software-as-a-Service (SaaS) options, may present some challenges. The most common challenge 2nd Watch encounters with clients is not fully understanding the options available in modern environments. Older applications are the product of their time and typically were built optimally for the available technology and needs. However, when rearchitecting those applications, sometimes development teams either don’t know or don’t have details about better options that may be available. 

Running a MySQL database on the same machine as the rest of the monolithic application may have made sense when initially writing the application. Today, many applications can run more cheaply, more securely, and with the same or better performance using a combination of cloud storage buckets, managed caches like Redis or Memcached, and secrets managers. These consumption-based cloud options tend to be significantly cheaper than managed databases or databases running on cloud virtual machines. Scaling automatically with end-user demand and reduced management overhead are additional benefits of software modernization. 

Rearchitecting an application can also be frustrating for experienced systems administrators tasked with maintaining and troubleshooting production applications. For example, moving from VMs to containers introduces an entirely different way of dealing with logs. Sysadmins must forward them to a log aggregator instead of storing them on disk. Autoscaling a service can mean the difference between identifying which instances – of potentially dozens or hundreds – had an issue instead of a small handful of them. Application modernization impacts every person involved with the long-term success of that application, not just developers and end-users. 

Conclusion 

Application Modernization is a long-term strategic activity, not a short-term tactical activity. Over time, you will realize the benefits of the lower total cost of ownership (TCO), increased agility, and faster time to market. Recognizing and committing to the future of your business will help you overcome the short- and mid-term challenges of app modernization. 

Engaging a trusted partner to accelerate your app modernization journey and lead the charge across that gap is a powerful strategy to overcome some of the highlighted problems. It can be difficult to overcome a challenge with the same mindset that led to creating that challenge. An influx of different ideas and experiences can be the push development teams need to reach the next level for a business.

How to Choose the Best Cloud Service Provider for your Application Modernization Strategy

If the global pandemic taught us anything, it’s that digital transformation is a must-have for businesses to keep up with customer dCloud Service Provider for App Modernization Strategyemands and remain competitive. To do this, organizations are moving their workloads to and modernizing their applications for the cloud faster than ever.

In fact, according to a recent survey, 91% of respondents agree or strongly agree that application modernization plays a critical role in their organization’s adaptability to rapidly changing business conditions. But there are so many cloud service providers to choose from! How do you know which one is best for your application modernization objectives? Keep reading to find out!  

What is a Cloud Services Provider (CSP)? 

A cloud services provider is a cloud computing company that provides public clouds, managed private clouds, or on-demand cloud infrastructures, platforms, and services. Many CSPs are available worldwide, including Alibaba Cloud, Amazon Web Services (AWS), Google Cloud Platform (GCP), IBM Cloud, Oracle Cloud, and Microsoft Azure. However, three industry giants are noteworthy because of their services and global footprint: Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure. 

What is a Cloud Services Provider (CSP)?

What is Application Modernization? 

Application modernization is the process of revamping an application to take advantage of breakthrough technical innovations to improve the overall efficiency of the application remarkably. This efficiency typically involves high availability, increased fault tolerance, high scalability, improved security, eliminating a single point of failure, disaster recovery, contemporary and simplified tools, new coding language, and reduced resource requirements, among other benefits. Many companies running legacy applications are now looking at how they can best modernize their monolith applications. 

Application Rationalization: The First Step to Modernization 

The best way to start any application modernization journey is with application rationalization. In this process, you identify company-wide business applications and strategically determine which ones you should keep, replace, retire, or consolidate. Once you identify those applications, you can list each one’s ease or difficulty level, total cost of ownership (TCO), and business value, enabling you to decide and prioritize which action to take. (Hint: Start with high value and minimal effort apps!) Doing this will also help you eliminate redundancies, lower costs, and maximize efficiency. 

The high-value apps that are difficult to move to the cloud will likely cause the most grief in your decision-making process. But, like Rome, your modernization strategy doesn’t need to be built in a day.

You can develop an approach to application modernization over time and still reduce costs and risks while moving your portfolio forward.  

It is crucial to evaluate your current application stack and determine the most suitable application modernization strategy to migrate to the cloud when it comes to application modernization in the cloud. Many on-premises applications are legacy monoliths that may benefit more from refactoring than a rehosting (“lift and shift”) approach. (Check out Rehost, Refactor, Replatform – What, When, & Why? | AppMod Essentials) 

Refactoring may require overhauling your application code, which takes some high-level effort but offers the most benefits. However, not all applications are ideal candidates for refactoring. Rearchitecting will become necessary for some obsolete applications that are not compatible with the cloud due to architectural designs made while building the app. In this scenario, the value proposition considers rearchitecting, dividing the application into several functional components that can be individually adapted and further developed. These small, independent pieces—or “microservices”—can then be migrated to the cloud quickly and efficiently.

Determining the Best Cloud Services Provider for Your Application Modernization 

Each application modernization journey is unique, as is the process of choosing the best cloud service provider that meets your demands. What works for one business’ application may not be the best for yours, even if they are in the same industry. And just because a competitor has chosen one CSP over another does not mean you should. 

When evaluating the CSP that is best for you, consider the following: 

Service Level Agreements (SLAs): Determine if the CSP’s service level agreements suit your production workloads, whether the cloud service is generally available yet, and they retain satisfactory levels of support knowledge. Managing workloads in the cloud can sometimes be tedious. The managed services department may not have the required expertise to efficiently manage and monitor the cloud environment. It is critical to your business to do your due diligence to ensure your preferred CSP can administer their managed offerings with as close to zero downtime as possible. 

  • Vendor Lock-in: It is important to have alternatives to any single CSP and that you retain the flexibility to substitute for a better value proposition. 
  • Enterprise Adoption: Consider the likelihood of scalability of your use of the CSP across your organization. 
  • Economic Impact: Consider the positive business or financial impacts that result from the service usage at the individual, department, and company-wide levels. 
  • Automation and Deployment: Verify the CSP’s integration capabilities with your organization’s preferred automation tooling and availability of automated and local testing frameworks.  

CSP Application Modernization Design Considerations 

When modernizing existing applications to take the best advantage of the cloud, cloud technologies like serverless and containers are good options to consider. Serverless computing and containers are cloud-native tools that automate code deployment into isolated environments. Developers can build highly scalable applications with fewer resources within a short time. They both also reduce overhead for cloud-hosted web applications but differ in many ways. Private cloud, hybrid cloud, and multi-cloud approaches to application modernization are worth considering too. 

Serverless Computing and Containers 

Serverless Computing and Containers Serverless computing is an exaction model where the CSP executes a piece of code by dynamically allocating the resources and can only charge for the services used to run the code. Code is typically run in stateless containers. Various events such as HTTP requests, monitoring alerts, database events, queuing services, file uploads, scheduled events (cron jobs), and more can trigger them.

 

The cloud service provider then receives the code in a function to execute, which is why serverless computing is sometimes referred to as a Function-as-a-Service (FaaS) platform. Add that to your list of as-a-Service acronyms: IaaS, PaaS, SaaS, FaaS!   

The FaaS offerings of the three major CSPs are: 

Containers provide a discrete environment set up within an operating system. They can run one or more applications, typically assigned only those resources necessary for the application to function correctly. Because containers are smaller and faster than virtual machines, they allow applications to run quickly and reliably among various computing environments. Container images become containers at runtime and include everything needed to run an application: code, runtime, system tools, system libraries, and settings. 

Private, Hybrid, and Multi-Cloud 

The public cloud is a vital part of any modernization strategy. However, some organizations may not be ready to go directly to the public cloud from the datacenter. Cloud architects should consider private, hybrid, and multi-cloud strategies in those cases. These models can help resolve any architectural, security, or latency concerns. They will also reduce the complexity associated with the policies for specific workloads based on their unique characteristics.  

Conclusion 

Migration to the cloud is ideal for investing in application modernization as it can lower your overall operational costs and increase your application’s resiliency. But not all use cases—nor cloud service providers—are the same. You need to do your homework before choosing the best-suited one for your business.

Rehost vs Refactor vs Replatform | AppMod Essentials

Migrating workloads or an application to the cloud can seem daunting for any organization. The cloud is synonymous with industry buzzwords such as DevOps, digital transformation, opensource, and more. As of 2021, AWS has over 200 products and services.

Nowadays, every other LinkedIn post is somehow related to the cloud. Sound familiar? Maybe a bit intimidating? If so, you are not alone! Organizations often hope that operating in the cloud will help them become more agile, enhance business continuity, or reduce technical debt. All of which are achievable in a cloud environment with proper planning. 

AppMod Essentials: Rehost, Refactor, Replatform

Benjamin Franklin once said, “By failing to prepare, you are preparing to fail.” This sentiment is true not only in life but also in technology. Any successful IT project has a strategy and tangible business outcomes. Project managers must establish these before any “actual work” begins. Without this, leadership teams may not know if the project is on task and on schedule. Technical teams may struggle to determine where to start or what to prioritize. Here we’ll explore industry-standard strategies that organizations can deploy to begin their cloud journey and help technical leaders decide which path to take. 

What is Cloud Migration? 

Cloud migration is when an organization decides to move its data, applications, or other IT capabilities into a cloud service provider (CSP) such as Amazon Web Services (AWS), Google Cloud Platform (GCP), or Microsoft Azure. Some organizations may decide to migrate all IT assets into the cloud; however, most organizations keep some services on-premises in a hybrid environment for various reasons. Performing a migration to the cloud may consist of multiple CSPs or even a private cloud. 

What Are the Different Strategies for Cloud Migration? 

What Are the Different Strategies for Cloud Migration?Gartner recognizes five cloud migration strategies, nicknamed “The 5Rs.” Individually they are called rehost, refactor, revise (a.k.a. replatform), rebuild, and replace, each with benefits and drawbacks. This blog focuses on three of those five migration approaches—rehost, refactor, and replatform—as they play a significant role in application modernization. 

What is Rehost in the Cloud?

Rehost, or “lift and shift,” is the process of migrating a workload into the cloud as-is without any modifications. Rehosting usually involves infrastructure-as-a-service (IaaS) technologies in a cloud provider such as AWS EC2 or Azure VM’s. Organizations with little cloud experience may consider this strategy because it is an easy start to their cloud journey. Cloud service providers are constantly creating new services for rehosting to make the process even easier. This strategy is less complex, so the timeline to complete a rehost migration can be significantly shorter than other strategies. Organizations often rehost workloads and then modernize after gaining more cloud knowledge and experience. 

Rehosting Pros:

  • No architecture changes – Organizations can migrate workloads as-is, which benefits those with little cloud experience. 
  • Fastest migration method – Rehosting is often the quickest path to the cloud. This method is an excellent advantage for organizations that need to vacate an on-premises data center or colocation. 
  • Organizational changes are not necessary – Organizational processes and strategies to manage workloads can remain the same since architectures are not changing. Organizations will need to learn new tools for the selected cloud provider, but the day-to-day tasks will not change.  

  Rehosting Cons: 

  • High costs – Monthly spending will quickly add up in the cloud without modernizing applications. Organizations must budget appropriately for rehosting migrations. 
  • Lack of innovation – Rehosting does not take advantage of the variety of innovative and modern technologies available in the cloud.  
  • Does not improve the customer experience – Without change, applications cannot improve, which means customers will have a similar experience in the cloud. 

What Refactor Means?

Use the refactoring technique to update and optimize applications for the cloud. Refactoring often involves “app modernization” or updating the application’s existing code to take full advantage of cloud features and flexibility. This strategy can be complex because it requires source code changes and introduces modern technologies to the organization. These changes will need to be thoroughly tested and optimized, leading to possible delays. Therefore, organizations should take small steps by refactoring one or two modules at a time to correct issues and gaps at a smaller scale. Although refactoring may be the most time-consuming, it can provide the best return on investment (ROI) once complete.  

Refactoring Pros: 

  • Cost reduction – Since applications are being optimized for the cloud, refactoring can provide the highest ROI and reduce the total cost of ownership (TCO). 
  • More flexible application architectures – Refactoring allows application owners the opportunity to explore the landscape of services available in the cloud and decide which ones fit best. 
  • Increased resiliency – technologies and concepts like auto-scaling, immutable infrastructure, and automation can increase application resiliency and reliability. Organizations should consider all of these when refactoring. 

Refactoring Cons:

  • A lot of change – Technology and cultural changes can be brutally painful. Cloud migrations often combine both, which compounds the pain. Add the complexity of refactoring, and you may have full-blown mutiny without careful planning and strong leadership. Refactoring migrations are not for the faint of heart, so tread lightly. 
  • Advanced cloud knowledge and experience are needed – Organizations lacking cloud experience may find it challenging to refactor applications by themselves. Organizations may consider using a consulting firm to address skillset gaps. 
  • Lengthy project timelines – Refactoring hundreds of applications doesn’t happen overnight. Organizations need to establish realistic timelines before starting a refactor migration. 

What's your application modernization maturity level

What is Replatform in Cloud?

Replatforming is a happy medium between refactoring and rehosting and applies a series of changes to the application to fit the cloud better without rearchitecting the whole thing versus completely overhauling the application as you would expect from refactoring. Replatforming projects often involve rearchitecting the database to a more cloud-native solution, adding scaling mechanisms, or containerizing applications. 

Replatorming Pros:

  • Reduces cost – If organizations take cost-savings measures during replatforming, they will see a reduction in technical operating expenses. 
  • Acceptable compromise – Replatforming is considered a happy medium of adding features and technical capabilities without jeopardizing migration timelines. 
  • Adds cloud-native features – Replatforming can add cloud technologies like auto-scaling, managed storage services, infrastructure as code (IaC), and more. These capabilities can reduce costs and improve customer experience. 

Replatforming Cons:

  • Scope creep may occur – Organizations may struggle to draw a line in the sand when replatforming. It can be challenging to decide which cloud technologies to prioritize. 
  • Limits the amount of change that can occur – Everything cannot be accomplished at once when replatforming. Technical leaders must decide what can be done given the migration timeline then add the remaining items to a backlog. 
  • Cloud and automation skills needed – Organizations lacking cloud experience may struggle replatforming workloads by themselves. 

Which cloud migration strategy is best for your organization? 

As stated above, it is essential to have clear business objectives for your organization’s cloud migration. Just as important is establishing a timeline for the migration. Both will help technical leaders and application owners decide which strategy is best. Below are some common goals organizations have for migrating to the cloud. 

Common business goals for cloud migrations:

  • Reduce technical debt 
  • Improve customer’s digital experience 
  • Become more agile to respond to change faster 
  • Ensure business continuity 
  • Evacuate on-premises data centers and colocations 
  • Create a culture of automation 

Determining the best migration strategy is key to getting the most out of the cloud and meeting your business objectives. It is common for organizations to use all three of these strategies in tandem and often work with trusted advisors like 2nd Watch to determine and implement the best. When planning your cloud migration strategy, consider these questions:  

Cloud Migration Strategy Considerations:

  • Is there a hard date for migrating the application? 
  • How long will it take to modernize? 
  • What are the costs for “lift and shift,” refactoring, and/or replatforming? 
  • When is the application being retired? 
  • Can the operational team(s) support modern architectures? 

Conclusion 

In today’s world, the cloud is where the most innovation in technology occurs. Companies that want to be a part of modern technology advancements should seriously consider migrating to the cloud. Organizations can achieve successful cloud migrations with the right strategy, clear business goals, and proper skillsets.

4 Must-Have Steps to Application Modernization Success

To be successful in today’s landscape, organizations must deliver memorable customer experiences, demonstrate innovation, and be adaptable to the constant shifts of the marketplace. Embracing cloud technology is imperative to achieve these high levels of scalability and agility while minimizing current and future technical debt. However, moving to the cloud is only one (albeit significant) component of modernizing a business’s applications. Application modernization is a must.

4 Must-Have Steps to Application Modernization Success

Application modernization is when you take existing legacy applications and digitally transform their platform infrastructure, internal architecture, and/or features. It’s going from tightly-coupled systems with various dependencies to loosely-coupled ones that improve application scalability, resilience, and extensibility. The goal of application modernization is to create a more agile, flexible, and highly available application environment.

However, simply lifting and shifting complex monolithic applications to a public cloud service provider is not equivalent to becoming a modern enterprise. Migrating to the cloud can help speed up innovation, but if businesses do not build cloud-native applications, they are simply moving workloads. To maximize the benefits of the cloud and become a modern business, organizations must strive to be cloud-native.

Why is migration to the cloud necessary for application modernization?

One of the top reasons to migrate to the cloud is to increase business agility, velocity, and scalability. Companies also enjoy increased productivity and efficiency of their workforce when they utilize cloud infrastructure. The cloud enables organizations to digitally transform their business with modern technologies and reestablish their applications within a modern framework.

When a business migrates to the cloud, that shouldn’t be considered the “finish line” in its modernization journey. The cloud is a means to an enterprise’s modernization efforts. An organization also has to update its culture and processes to enable high-performing software development if it is truly looking to modernize its application environment.

CTA 2nd Watch

Why is application modernization necessary?

The bottom line is that modernizing applications will generate more business. Refusing to update infrastructure, technology, applications, and approaches to software development will place a company significantly behind in a race where there are very responsive and innovative competitors. Enterprises that were not born digital must evolve quickly to stay afloat in today’s ultra-demanding landscape.

Application modernization is not simply a survival tactic, but it is also a crucial method to achieve business agility. Digital transformation offers some of the following measurable outcomes and benefits to a company:

Optimize costs and resources

Modernizing applications utilizing cloud service providers can save businesses money. Planning a cloud migration can significantly reduce the total cost of ownership (TCO), allowing organizations to focus on their core business and missions rather than expending energy on managing servers and on-premise infrastructures.

Additionally, by using cloud platforms, enterprises have access to a variety of robust services and automation tools that will eventually result in noticeable savings and cost optimization both of time and money. Deploying enterprise solutions via a cloud service provider allows organizations to retire expensive legacy infrastructure, reduce time and fiduciary costs, experience agility through automation, and reallocate resources towards other imperative business needs.

Mitigate risk

Staying up to date with compliance and security standards is non-negotiable. Modernization enables companies to support mandated and critical changes such as regulatory compliance in a punctual manner. Enterprises can use modernization initiatives to invest in technology and process improvements necessary for security requirements.

Work with a trusted and experienced cloud partner

The migration process to the cloud requires working with a provider who has experience in retiring legacy systems and emerging technologies to migrate databases, servers, and data. Working with a cloud service provider and/or a cloud advisory firm enables businesses to modernize their applications smoothly. Cloud partners provide access to the vital tools and knowledge needed to digitally transform a business. Harnessing the power of cloud-native firms can improve operational efficiency, increase scalability, and improve the overall performance of an organization.

What are the steps of application modernization?

For most enterprises, app modernization is the clear path forward. The question is not whether to modernize but “what” and “how” to modernize. To answer these crucial questions about their legacy applications, organizations need to understand their modernization options and have a deep insight into their applications.

What are the steps of application modernization?Application modernization is much more than simply migrating to cloud-based workloads. It is the total transformation of an organization’s culture, tools, and processes. Below is a step-by-step strategy for continuous application modernization:

#1: Create Goals for Modernization

Goals will always be the foundation of any strong strategy. Without goals, measuring the success of modernization efforts will be incredibly difficult, if not impossible. You have to detail your goals for app modernization and link modernization efforts to measurable business outcomes. For example, greater agility and faster time-to-market with new features can show progress and success as a business embarks on its modernization journey.

Organizations should identify the highest priority and most critical applications to kick off the goal-setting process. From there, they should analyze how the company would benefit from increased reliability, scalability, and performance by leveraging their cloud service provider. Areas of impact can include revenue, market share churn, profitability, and more.

After an enterprise has clearly defined how current applications will impact their business success, they can then tie modernization objectives and priorities back to business outcomes.

#2: Understand Your Applications

Before a business can transform its applications, it must recognize its starting point. An organization should take a baseline measurement to understand how its applications are performing. This baseline allows businesses to identify and prioritize the best approach to application modernization for each app and will serve as the foundation for creating the road map for application modernization.

Companies must invest in an observability platform to aggregate, correlate and analyze performance data. Without this, they cannot make data-driven decisions because there is no true understanding of how an application is currently functioning and if modernization is improving it. Observability allows enterprises to capture data about each application to help understand their specific characteristics. This objective and holistic view of applications empowers organizations to decide how to best modernize an application.

#3: Determine the Optimal Modernization Approach for Each Application

After setting goals and collecting data, companies are ready to make data-driven decisions on modernizing their applications. There are three approaches to app modernization: rehosting, replatforming, and refactoring.

Rehosting entails shifting an application to a more modern environment, such as the cloud, to reap cost savings, performance improvements, and ease of operations. The changes only pertain to rehosting; therefore, this approach’s risk and impact are low.

Replatforming is when companies move an application and modify some infrastructure elements for time and resource-saving purposes. Replatforming requires taking an existing component of an application and moving it to a managed service with no changes to business logic. The risk is still low because of infrastructure modifications, but the impact is medium.

Refactoring requires businesses to re-architect an application to optimize and realize the full benefits of cloud services, architectures, and technologies. It allows for improved quality, performance, and the rapid delivery of innovative new features. Re-architecting applications require making code-level changes, so the risk of refactoring is high but ultimately yields a more significant impact.

#4: Observe and Optimize

Taking a baseline measurement in step two gives companies the data to make informed decisions and serves as a comparison during and after modernization efforts. Once the first modernization iteration is complete, organizations can track their goals and demonstrate success by comparing the previous baseline against current performance and other KPIs, such as business outcome data and customer experience. The hope is to see improvements and identify additional modernization opportunities to achieve peak cloud optimization.

Modernization is continuous

The strategy, as mentioned above, is a never-ending process and should be repeated. There will always be new tools and capabilities for companies to discover, incorporate, and support throughout app modernization.

Each iteration of modernization is an opportunity for enterprises to embrace digital transformation holistically. An application modernization strategy is not simply lifting and shifting platforms; it also reshapes an organization’s culture and processes necessary for truly modernizing a business.

Riding the Digital Transformation: Why Enterprises Are Reengineering Their Cloud Infrastructure

Post 2020, how are you approaching the cloud? The rapid and unexpected digital transformation of 2020 forced enterprises worldwide to quickly mobilize workers using cloud resources. Now, as the world returns to an altered normal, it’s time for organizations to revisit their cloud infrastructure components with a fresh perspective. Hybrid work environments, industry transformations, changing consumer behavior, and growing cyber threats have all effected the way we do business. Now it might be time to change your cloud.

Cloud Infrastructure and digital transformatio

Risk mitigation at scale

Avoiding potential missteps in your strategy requires both wide and narrow insights. With the right cloud computing infrastructure, network equipment, and operating systems, organizations can achieve better risk mitigation and management with cloud scalability. As you continue to pursue business outcomes, you have to solve existing problems, as well as plan for the future. Some of these problems include:

  • Scaling your cloud platform and infrastructure services quickly to keep up with increasing and/or unexpected demand.
  • Maximizing cloud computing services and computing power to accommodate storage, speed, and resource demands.
  • Prioritizing new and necessary investments and delivery models within a fixed budget.
  • Innovating faster to remain, or gain, competitive advantage.

Overall, to avoid risk, you need to gain efficiency, and that’s what the cloud can do. Cloud infrastructure, applications, and Software as a Service (SaaS) solutions are designed to decrease input, and increase output and effectiveness. The scalability of cloud services allows enterprises to continue growing and innovating, without requiring heavy investments. With continuous cloud optimization, you’re positioned to adapt, innovate, and succeed regardless of the unknown future.

Application modernization for data leverage

Much of the digital transformation started with infrastructure modernization and the development of IaaS as a base line. Now, application modernization is accelerating alongside a changing migration pattern. What used to be simply ‘lift and shift’ is now ‘lift and evolve.’ Enterprises want to collaborate with cloud experts to gain a deeper understanding of applications as they become more cloud native. With a constant pipeline of new applications and services, organizations need guidance to avoid cloud cost sprawl and streamline environment integration.

As application modernization continues, organizations are gaining access to massive amounts of data that are enabling brand new opportunities. This requires a new look at database architectures to make sure you’re unlocking value internally and potentially, externally. While application modernization and database architecture are interconnected, they can also transform separately. We’re starting to see people recognize the importance of strategic cloud transformations that include the entire data footprint – whether it’s the underlying architecture, or the top level analytics.

Organizations are getting out of long-term licensing agreements, monetizing their data, gaining flexibility, cutting costs, and driving innovation, customer value, and revenue. Data is pulled from, and fed into, a lot of different applications within constantly changing cloud environments, which brings both challenges and opportunities. Enterprises must transform from this to that, but the end goal is constantly changing as well. Therefore continuous motion is necessary within the digital transformation.

Changing core business strategies

One thing is for sure about the digital transformation – it’s not slowing down. Most experts agree that even after pandemic safety precautions are eliminated, the digital transformation will continue to accelerate. After seeing the speed of adoption and opportunities in the cloud, many enterprises are reevaluating the future with new eyes. Budgets for IT are expanding, but so is the IT skills gap and cybersecurity incidents. These transitions present questions in a new light, and enterprises should revisit their answers.

  • Why do you still have your own physical data center?
  • What is the value in outsourcing? And insourcing?
  • How has your risk profile changed?
  • How does data allow you to focus on your core business strategy?

Answering these questions has more enterprises looking to partner with, and learn from, cloud experts – as opposed to just receiving services. Organizations want and need to work alongside cloud partners to close the skills gap within their enterprise, gain skills for internal expansion in the future, and better understand how virtualized resources can improve their business. It’s also a way to invest in your employees to reduce turn-over and encourage long-term loyalty.

Security and compliance

At this point with security, compliance, and ensuring business continuity, enterprises must have solutions in place. There is no other way. Ransomware and phishing attacks have been rising in sophistication and frequency year-over-year, with a noticeable spike since remote work became mainstream. Not only does your internal team need constant training and regular enforcement of governance policies, but there’s a larger emphasis on how your network protections are set up.

Regardless of automation and controls, people will make mistakes and there is an inherent risk in any human activity. In fact, human error is the leading cause of data loss with approximately 88% of all data breaches caused by an employee mistake. Unfortunately, the possibility of a breaches is often made possible because of your internal team. Typically, it’s the manner in which the cloud is configured or architected that creates a loophole for bad actors. It’s not that the public cloud isn’t secure or compliant, it’s that it’s not set up properly. This is where many enterprises are outsourcing data protection to avoid damaging compliance penalties, guarantee uninterrupted business continuity, and maintain the security of sensitive data after malicious or accidental deletion, natural disaster, or in the event that a device is lost, stolen or damaged.

Next steps: Think about day two

Enterprises who think of cloud migration as a one-and-done project – we were there, and now we’re here – aren’t ready to make the move. The cloud is not the answer. The cloud is an enabler to help organizations get the answers necessary to move in the direction they desire. There are risks associated with moving to the cloud – tools can distract from goals, system platforms need support, load balancers have to be implemented, and the cloud has to be leveraged and optimized to be beneficial long-term. Without strategizing past the migration, you won’t get the anticipated results.

It can seem overwhelming to take on the constantly changing cloud (and it certainly can be), but you don’t have to do it alone!

App Modernization in the Cloud

The cloud market is maturing, and organizations worldwide are well into implementing their cloud strategies. In fact, a recent McKinsey survey estimates that, by 2022, 75% all workloads will be running in either public or private clouds. Additionally, according to VMWare, 72% of businesses are looking for a path forward for their existing applications, and it is important to consider an app modernization strategy as part of these migration efforts.

Whether it be a desire to containerize, utilize cloud-native services, increase agility, or realize cost savings, the overall goal should be to deliver business value faster in the rapidly changing cloud environment.

Modern Application

Application modernization has a focus on legacy or “incumbent” line of business applications, and approaches range anywhere between re-hosting from the datacenter to cloud, to full cloud native application rewrites. We prefer to take a pragmatic approach, which is to address issues with legacy applications that hinder organizations from realizing the benefits of modern software and cloud native approaches, while retaining as much of the intellectual property that has been built into incumbent applications over the years as possible. Additionally, we find ways of augmenting existing code bases to make use of modern paradigms.

Application Modernization Strategies

When approaching legacy software architecture, people often discuss breaking apart monolithic applications and microservices. However, the most important architectural decisions should be centered around how to best allow the application to function well in the cloud, with scalability, fault-tolerance, and observability all being important aspects. A popular approach is to consider the tenants of the 12-Factor App to help guide these decisions.

Architecture discussions go hand in hand with considering platforms. Containerization and serverless functions are popular approaches, but equally valid is traditional VM clustering or even self-hosting. Additionally, we start to think about utilizing cloud services to offload some application complexity, such as AWS S3 for document storage or AWS KMS for key management. This leads us to consider different cloud providers themselves for best fit for the organization and the applications overall, whether it be AWS, Azure, GCP (Google cloud platform), or hybrid-cloud solutions.

Another very important aspect of application modernization, especially in the cloud, is ensuring that applications have proper automation.

Strong continuous integration and continuous deployment (CI/CD) pipelines should be implemented or enhanced for legacy applications. Additionally, we apply CD/CI automation for deploying database migrations and performing infrastructure-as-code (IaaC) updates, and ensure paradigms like immutable infrastructure (i.e. pre-packaging machine images or utilizing containerization) are utilized.

Last, there is an important cultural aspect to modernization from an organizational to team level. Organizations must consider modernization a part of their overall cloud strategy and support their development teams in this area. Development teams must adapt to new paradigms to understand and best utilize the cloud – adopting strong DevOps practices and reorganizing teams along business objectives instead of technology objectives is key.

By implementing a solid modernization strategy, businesses can realize the benefits the cloud provides, deliver value to their customers more rapidly, and compete in a rapidly changing cloud environment.
