In another project based in a real-world scenario, I acted as the Cloud Specialist responsible for migrating a workload running in a Corporate DataCenter to AWS.
The application and database were migrated to AWS using the Lift & Shift (rehost) model, moving both application and database data.
I followed some migration steps :
- Planning (sizing, prerequisites, resource naming),
- Execution (resource provisioning, best practices),
- Go-live (validation test — Dry-run, final migration — Cutover)
- And, Post Go-live (ensure the operation of the application and user access).
