AWS Cloud Migration Phases
Amazon's cloud migration guide outlines five phases for migration to the AWS cloud. The first phase involves Migration Preparation and Business Planning, where you need to understand your current situation, define your objectives, and decide which applications to move to the cloud. Discover and Planning is the second phase, where you examine your IT portfolio, consider migration strategies for each application, and explore AWS migration tools like Server Migration Service and Database Migration Service. Designing, Migrating, and Validating Applications and Operation are the remaining phases where you create migration plans, start with a Proof of Concept, get buy-in from stakeholders, and finally operate applications within AWS.
6 AWS Migration Strategies
Amazon recommends six strategies for migrating on-premise applications to the cloud. These include Rehost ("lift and shift"), suitable for large legacy migrations with a scarcity of cloud technology skills, Replatform ("lift, tinker and shift"), which involves minimal changes but takes advantage of AWS services, Repurchase ("drop and shop"), where the application is replaced entirely with Amazon or cloud services, Refactor/Re-architect, for complete overhaul for cloud-native environment, Retire, to identify and turn off unused applications, and Retain, for applications not ready for migration. Each strategy has its benefits and challenges, and careful consideration is crucial when selecting the most appropriate one.
