The three-phase migration process – Leveraging the Cloud for Digital Transformation
The three-phase migration process
The followings are three phases of cloud migration:
- Assessment phase – This is the discovery phase where; you can assess your on-premises or co-location resources and build out a right-sized and optimized cost projection for your specific needs for running workloads in the cloud. You can build a Migration Readiness Assessment (MRA) to evaluate an organization’s cloud readiness using AWS Migration Evaluator, formerly known as TSO Logic. You can use AWS Cloud Adoption Framework (CAF) to guide cloud readiness and migration organizations. You will learn details about CAF later in this chapter.
- Mobilize phase- In the Mobilize phase, you address gaps in your organization’s readiness uncovered in the assessment phase. Your focus should be on building your baseline environment, driving operational readiness, and developing cloud skills. You can use the AWS cloud adoption readiness tool that helps you develop plans for your cloud adoption based on your migration readiness. Further, the AWS Migration hub helps automate the planning and tracking of application migration across multiple AWS and Partner tools, allowing you to choose the migration tools that best fit your needs.
- Migrate phase– During the Migrate & Modernize phase, each of your workloads will be designed, migrated, and validated. AWS Migration Hub enables you to get progress updates quickly across all your migrations, easily identify and troubleshoot any issues, and reduce the overall time and effort spent on your migration projects. For many workloads, the best approach is to move rapidly to the cloud, then re-architect in AWS. Many businesses use migration as a valuable opportunity to also modernize their businesses by refactoring their legacy technology.
The above three-phase process is the best way for your organization to efficiently and quickly migrate hundreds of workloads. And while all three phases are standard components of a successful migration, they are not set in stone. For example, an initial application migration develops into an iterative process of migrating additional applications and workloads to AWS. As you migrate more workloads, you can enable repeatable and predictable process processes and procedures, accelerating and optimizing your migration efforts.Let’s review the migration patterns, also known as “The 7 R’s,” when migrating to the cloud and learn when to pick one over the others.
