Prioritized applications assessment
One of the key outcomes of the previous stage, portfolio discovery and initial planning, was to prioritize a subset of applications for detailed assessment. This section explores the detailed assessment of applications.
Looking at the details of a few applications early on will drive acceleration. The process of assessment and to-be architecture design surfaces potential blockers and clarifies important tasks that precursors to the larger-scope migration. These tasks include gathering requirements to establish AWS foundations, such as the landing zone on AWS, or to extend and validate the existing landing zone. This assessment is also the time to consider the steps and the strategy for migration.
The primary outcomes of this stage are the following:
Validated list of prioritized applications
Documented current state architecture
Documented target architecture and migration strategy for migration candidates
Identified migration patterns and tooling
Documented platform requirements (security, AWS infrastructure, and operations)
Documented cutover considerations for migration planning
Estimated AWS run rate
