AWS Application Modernization: Unlocking the Power of Cloud Innovation

7 min read Mar 06, 2024

Given the fact that we live in an era where technology rapidly evolves, we also must recognize the need for businesses to update their legacy systems to stay competitive. Application modernization, especially through cloud computing, has emerged to be a rather significant way of enhancing efficiency, scalability & agility, and Amazon Web Services (AWS) stands out as a powerful ally in this journey. It is known for offering over 200 services that are designed to streamline the transition to modern, cloud-based solutions. 

Modernizing applications on AWS is more than just transferring existing software to the cloud, it also involves re-engineering applications to fully exploit cloud capabilities to gain significant improvements in performance along with cost savings. It is safe to admit that this push towards AWS modernization is driven by the limitations of outdated systems which are often too expensive to maintain and lack the flexibility required for today's dynamic business environment. 

Join us on this journey as we get ready to explore the significance of AWS application modernization, outlining the application services involved, strategies for effective modernization, best practices, & future trends in cloud innovation. If you are one of those organizations looking to modernize your applications, understanding AWS's role in this process will enable you to leverage the cloud's full potential.

These services can be leveraged by organizations to address various app modernization needs, from migrating legacy applications to the cloud to building new cloud-native applications. Each service offers specific features and benefits that makes it essential to understand their potential impact on your modernization strategy. 

Now that you are familiar with various AWS services, let’s delve into the strategies businesses can employ to effectively modernize their applications using these services for a smooth transition to the cloud. 

Strategies for Effective AWS Application Modernization 

Modernizing applications with AWS requires a strategic approach that not only considers the technological shift but also aligns with business goals and operational efficiencies. App modernization using AWS is typically divided into three phases – assessing, modernizing, and managing. Here is the strategy we follow at Seasia to ensure an effective application modernization journey on AWS:

Assess and Plan 

  • We begin by evaluating your existing application portfolio to identify which applications are suitable for modernization. Next, we use AWS's Application Discovery Service to gather detailed information about your on-premises data centers, which makes it easier for us to plan migrations and estimate costs. 
  • We also take the time to clearly define your business objectives, such as cost reduction, scalability, and security, for modernization. This will guide your decision-making process throughout the modernization journey. 

Choose the Right Modernization Path 

Our app modernization experts will help you determine the most suitable modernization approach for your application. 

  • Rehosting (Lift and Shift): For quick wins with minimal disruption, we suggest considering rehosting your applications on AWS. This involves moving existing applications to AWS without changes. While it’s the fastest path, it might not fully leverage cloud-native features. 
  • Refactoring/Re-architecting: This approach involves making changes to the application design to fully utilize AWS cloud-native capabilities. It is important to note that even though it's more time-consuming, it results in greater agility, scalability, and cost-efficiency. 
  • Replatforming: Adjusting the application to fit into the cloud environment with minimal changes, such as using AWS RDS for databases, can yield significant benefits without the complexity of a full refactor. 

Leverage AWS Tools and Services 

  • Utilizing tools like AWS Migration Hub provides a centralized location to monitor and manage migrations from on-premises to the cloud, simplifying the process. 
  • Using AWS managed services, such as Amazon RDS or Amazon DynamoDB, we can help reduce the operational burden of managing databases, allowing your team to focus on innovation. 
  • We can also implement AWS DevOps tools like AWS CodeBuild, CodeDeploy, and CodePipeline to automate the software development lifecycle to enhance the overall efficiency of deploying and managing applications. 

Focus on Security and Compliance 

In addition to utilizing AWS’s comprehensive security tools and features to ensure that your modernized application adheres to the highest security standards, we also leverage their compliance programs to meet regulatory requirements relevant to your industry. AWS provides extensive resources to help navigate compliance considerations during the modernization process. 

Modernization is an ongoing process. We continuously assess the performance, cost, and security of your applications, by leveraging AWS’s flexibility to optimize resources and improve efficiency over time.
