The POC results will be captured for the continuous updating of low-level design document. The business cut over to the new cloud model will be carefully undertaken through various technical and governance measures
Planning
• Cloud Ready – validate cloud readiness, plan and document activities and key stakeholders for cloud migration (like-for-like or lift and shift migration or refactor)
• Assess and confirm the readiness of applications that may require OS/COTS version upgrades, Application code changes, and/or additional testing & validation when migrated to Cloud. Network security and load-balancing policies will need to be transformed as Cloud native network, security and load-balancing services will be likely deployed in the TO-BE state in Cloud.
• Validate and update migration waves that were developed during cloud discovery exercise – validate mappings, groupings, and exceptions with stakeholders and update as needed
• Analyze application-database dependencies and include these findings in the overall cloud migration plan
• Plan for the Cloud best practices while migrating to cloud
Cloud Infrastructure Needs and Design
• Validate and Review target sizing in cloud (compute, storage, Cloud services, security and network) and update target state infrastructure as required
• Design and document target state architecture for applications being migrated, taking into consideration: Scalability, High Availability, Disaster Recovery, Security and Operational Excellence
• Migration tools evaluation will be conducted and finalized during this phase.
Cloud Migration and Implementation
(Lift and Shift, Rehost, Replatform, Rewrite, Replace and Retire)
• Execute and manage in-scope data center server migrations to Cloud
• For each of application impacted by a migration wave: Perform infrastructure verification, Supervise the application verification, supervise abbreviated application testing of all applications impacted by migration wave
