As your organization moves existing applications to Amazon Web Services (AWS), you’ll need to decide on the right approach for each application: rehosting, replatforming, or refactoring. This third white paper in our Application Modernization series covers the latter approach.
Refactoring in its simplest form means changing application code for the better. Typically, the goal is to improve performance, quality, and maintainability. Refactoring for AWS expands those benefits and enables additional ones such as better availability, scalability, and reliability. Another major benefit refactoring provides is the ability to offload large amounts of undifferentiated work to AWS. Tasks such as hardware maintenance, operating system patch management, database updates, and more are all managed for you when using fully managed services such as Amazon Elastic Container Service (Amazon ECS), Amazon Elastic Kubernetes Service (Amazon EKS) ,or AWS Fargate, allowing your team to focus on what differentiates your business.
Granted, refactoring is the riskiest of the modernization strategies because it usually involves changing how an application works, either through logic or a significant shift in the underlying technology. At the same time, no other modernization approach delivers the level of positive impact and return on effort that refactoring can.
Read on to learn about the risks and benefits of refactoring, different types of refactoring in the AWS environment, and how New Relic can help you drive successful outcomes in the process.
