The migration factory approach is a powerhouse of top-tier practices, tools, and procedures that can empower organizations to migrate to AWS cloud easily. This systematic and all-encompassing strategy ensures a streamlined and effective migration process while mitigating potential risks. With the AWS Migration Factory, organizations can enjoy a hassle-free and efficient shift to the AWS cloud environment.

The AWS migration factory approach involves discovery & planning, portfolio analysis, application profiling, validation & testing, and post-migration support. In the discovery & planning step, organizations can collect valuable information on applications, dependencies, and performance metrics. Portfolio analysis involves scrutinizing the applications and the workload before AWS cloud migration. In this phase, organizations can effectively prioritize migration efforts and allocate resources by sorting them into factors like business criticality, complexity, and risk.

In application profiling, organizations assess the compatibility of each application with the AWS cloud environment. They identify potential obstacles and decide whether to choose Lift and Shift, a re-platforming strategy, or opt for a complete application re-architecture. Businesses must conduct thorough validation and testing during migration to guarantee that the applications operate correctly in the AWS infrastructure. Finally, after transitioning from the old legacy infrastructure to the new AWS cloud environment, evaluate all the cutovers and reassess the migration process.

As organizations migrate to AWS cloud, it’s crucial to identify and retire applications that are no longer useful or aligned with their goals. This step ensures an efficient cloud environment and minimizes unnecessary costs. The process begins with a comprehensive assessment of the application portfolio, which provides insights into each application’s performance and resource utilization. Based on this information, organizations can decide which applications to retire and which can become part of the AWS cloud environment.

Here’s a tip! Once you have gathered enough information on all the applications you believe to migrate, start categorizing them! It’s crucial to take the time to organize your applications based on their importance, how frequently they’re used, and how well they align with your business objectives. Break them down into four primary categories – “Retire,” “Migrate,” “Re-host,” and “Re-platform” – you can simplify your cloud environment and ensure that you’re optimizing your resources. Don’t hesitate to retire any applications that are no longer useful or redundant to streamline your processes.
