Blog 17 Modernization Strategies for Cloud Native Applications 2023

Introduction to Applications Modernization

Applications modernization is the process of re-architecting and re-platforming legacy applications to new, cloud-native architectures. The motivations for application modernization can be many, but often include a desire to improve application performance, scalability, and/or security; to reduce costs, or to take advantage of new features and capabilities offered by cloud-native platforms.

There are a number of strategies that can be employed when modernizing an application. One common strategy is lift-and-shift, in which an application is simply migrated “as is” to a cloud platform with minimal changes. This approach can be quick and easy, but may not take full advantage of the benefits that cloud platforms have to offer.

A more comprehensive approach is referred to as “rearchitecting.” This involves redesigning an application’s architecture to better take advantage of cloud-native features and capabilities. For example, an application might be refactored into microservices that can be deployed independently and scaled elastically as needed. Or, an application might be designed to make better use of containerization technologies such as Docker.

Regardless of the strategy employed, application modernization can be a complex and time-consuming process. But it can also offer significant benefits in terms of improved performance, scalability, security, and cost efficiency – making it well worth the effort for many organizations.

Why Modernize? Benefits of Moving to a Cloud-Native Architecture

There are many reasons to modernize your applications and move to a cloud-native architecture. One of the biggest benefits is increased scalability. Cloud-native architectures are designed to be highly scalable, so you can easily add more capacity when needed. This can be a major advantage over traditional on-premises deployments, which can be difficult and costly to scale.

Another benefit of cloud-native architectures is that they tend to be more resilient and fault-tolerant. This is because they typically use distributed systems and microservices, which can continue running even if one service fails. This can help keep your applications up and running even in the event of an infrastructure outage.

Finally, cloud-native architectures can offer better performance and improved security. Because they are designed for the cloud, they can take advantage of cloud-based security features and scale more automatically than traditional on-premises deployments. Additionally, because they often use containerization technologies, they tend to have lower latency and better performance than monolithic applications.

Step-by-Step Guide for Modernizing Apps

There are many reasons why you might want to modernize your existing applications. Maybe you’re looking to improve performance or scalability. Maybe you want to take advantage of new features in cloud-native applications, such as containers and microservices. Whatever your reasons, it’s important to have a plan for how you’re going to go about it.

That’s why we’ve put together this step-by-step guide for modernizing apps. We’ll walk you through the process of analyzing your existing app, identify what needs to be changed, and then give you some strategies for making those changes.

Let’s get started!

Step 1: Analyze Your Existing App

The first step is to take a close look at your existing application. What components make up the app? What language is it written in? What databases does it use? How is it deployed?

This evaluation will help you understand what needs to be changed in order for the app to be modernized. It will also give you an idea of the scope of the project, and whether or not it’s something that can realistically be completed in the timeframe that you have.

Step 2: Identify What Needs to Be Changed

Once you’ve taken a look at your app, identify what specifically needs to be changed in order to modernize it. This might include things like upgrading the coding language, using a cloud-native database, or transitioning to containers or microservices.

Make sure to break down the changes into manageable tasks that can be worked on in isolation. This will make it easier for you to tackle them one at a time and ensure that nothing is overlooked.

Step 3: Set Priorities

Once you’ve identified what needs to be changed, it’s time to set priorities. What needs to be done first, second, and so on? What are the most important changes that need to be taken care of immediately? And what tasks can wait until later?

It’s important to consider both short-term and long-term goals when setting priorities. You want to make sure your immediate needs are taken care of while also keeping in mind how each task fits into the overall goal of modernizing your application.

Step 4: Develop a Plan of Action

Now it’s time to start putting together a plan of action. This should include timelines for each task, as well as milestones and deliverables along the way. It should also define who is responsible for each task and how progress will be measured.

This plan will serve as a guide for your team as you begin to make changes to the application. It will also help ensure that everyone is on the same page and working towards the same goal.

Step 5: Implement Changes

Once you have a plan in place, you can start making changes to the app. This often involves refactoring code, updating libraries, or even rewriting parts of the application in order to modernize it. Depending on the size of your project and the complexity of your app, this could take days or weeks to complete.

It’s important to keep an eye on both the short-term goals and long-term goals during this process. Make sure to take advantage of any new features available with modernizing technologies, such as containers or microservices.

Step 6: Test Out Your Changes

After you’ve implemented all of your changes, it’s time to put them to the test. Run unit tests against specific elements of your application and stress tests against its overall performance under load. This will help you identify any issues that need to be addressed before deployment.

Step 7: Deploy Your App

Finally, it’s time to deploy your modernized application. Depending on how you’ve structured your code, this could involve moving the application to a new server, deploying changes to the cloud, or finally migrating everything to containers or microservices.

Challenges and Risks Faced During the Migration Process

The cloud-native application migration process can be challenging and risky. There are a few key areas that need to be considered when planning a migration:

Application Compatibility: Not all applications are compatible with the cloud. It is important to assess whether an application is a good candidate for migration before starting the process.

Data Migration: Migrating data to the cloud can be complex and time-consuming. There are a number of factors to consider, such as data format, volume, and security.

Operational Overhead: Migrating to the cloud requires additional operational overhead, such as provisioning and managing resources, monitoring performance, and responding to incidents.

Best Practices for Securing Your Cloud Infrastructure

As more and more businesses move to the cloud, it’s important to make sure that your infrastructure is secure. Here are some best practices for securing your cloud infrastructure:

  1. Use a reputable cloud provider: When choosing a cloud provider, make sure to pick one that has a good reputation for security. This will help ensure that your data is safe and secure.
  2. Keep your software up to date: Be sure to keep all of the software on your system up to date. This includes the operating system, as well as any applications you’re using. Outdated software can be a security risk, so it’s important to stay current.
  3. Configure your security settings: Take the time to properly configure all of the security settings on your system. This includes things like setting strong passwords and enabling two-factor authentication. By taking these measures, you can help keep your data safe from attackers.
  4. Monitor your system regularly: It’s important to monitor your system regularly for any signs of suspicious activity. If you see anything out of the ordinary, be sure to investigate further and take action as needed. By keeping an eye on things, you can help prevent serious security issues from occurring.

Cost Breakdown: The Pros and Cons of a Cloud Migration Strategy

As organizations look to modernize their applications, one key decision is whether to migrate to the cloud. While there are many benefits to cloud migration, such as increased agility and scalability, it’s important to weigh the costs before making a decision.

There are three main cost areas to consider when migrating to the cloud: upfront costs, operational costs, and exit costs. Upfront costs include things like licensing and professional services fees associated with migrating your application. Operational costs are those associated with running your application in the cloud, such as computing, storage, and bandwidth fees. Exit costs are incurred if you decide to move your application back out of the cloud (though this is typically not an issue since most providers offer flexible contracts).

When evaluating the cost of a cloud migration strategy, it’s important to consider both the short-term and long-term implications. In the short term, there may be a significant upfront investment required for things like licensing and professional services. However, in the long term, operational costs will often be lower in the cloud than on-premise due to economies of scale. As such, it’s important to consider your overall business goals when determining whether a cloud migration makes financial sense.

Different Types of Application Modernization Strategies

There are a few key strategies for modernizing applications for the cloud: lift and shift, re-platforming, and re-architecting.

Lift and shift is the simplest way to move an application to the cloud. You simply take your existing application and migrate it to a cloud provider with little or no changes. This can be a good option if you’re looking for a quick way to get your application into the cloud, but it doesn’t take advantage of many of the benefits of cloud computing.

Re-platforming is similar to lift and shift, but you also make some changes to your application to take advantage of cloud features like scalability and elasticity. This can involve changing how your application is deployed (for example, using containers instead of virtual machines), or changing how it stores data (for example, using a NoSQL database instead of a relational database).

Re-architecting is the most complex option, but it offers the most benefits. With re-architecting, you redesign your application from scratch to take advantage of cloud features. This means changing not just how it’s deployed and how it stores data, but also the overall architecture of the application. This can be a big undertaking, but it can pay off in terms of increased efficiency and flexibility.


Modernization strategies for cloud-native applications can be highly effective when done right. By leveraging the cloud’s scalability, security, and flexibility, developers can modernize their existing apps while still providing a great user experience. Furthermore, by utilizing containers to manage application workloads as well as deploying microservices architectures and serverless functions, organizations can drastically reduce time-to-market and maximize the value of their applications. Keeping these tips in mind is key to unlocking all that cloud-native applications have to offer.
