Course Outline
1. Migration Strategy and Business Context
- Drivers for cloud migration and definitions of success.
- Migration models: rehosting, replatforming, refactoring, repurchasing, retiring, and retaining.
- Setting goals, key performance indicators (KPIs), and defining organizational roles within migration programs.
2. Discovery, Evaluation, and Strategy
- Gathering inventory, mapping dependencies, and categorizing applications.
- Evaluating cloud compatibility and determining resource requirements.
- Prioritizing applications, structuring migration phases, and assessing risks.
3. Network, Security, and Landing Zone Design
- VPC architecture, connectivity solutions (VPN, Direct Connect), and hybrid models.
- Managing identity, access, encryption, and governance during the transition.
- Account structuring, landing zones, and establishing baseline controls.
4. Server Migration via AWS Application Migration Service (MGN)
- MGN architecture, replication mechanics, and configuration settings.
- Testing replicated servers, executing trial switchovers, and verifying application integrity.
- Final switchover protocols, post-migration verification, and rollback strategies.
5. Database Migration and Data Transmission
- DMS fundamentals: full load, change data capture (CDC), and ongoing replication.
- Schema transformation considerations and data validation methodologies.
- High-volume transfer options: DataSync, the Snow family, and secure network transfers.
6. Application Modernization and Refactoring Pathways
- Deciding when to replatform or refactor: utilizing containers, serverless, and managed services.
- Architectural patterns for modernization (microservices, event-driven systems).
- Incremental migration techniques: the strangler pattern and hybrid coexistence.
7. Testing, Switchover, and Operational Preparedness
- Establishing test plans, performance benchmarks, and QA verification.
- Coordinating switchovers, managing DNS, and implementing traffic switching strategies.
- Developing operational runbooks, backup procedures, monitoring, and incident response readiness.
8. Cost Efficiency, Performance Optimization, and Post-Migration Activities
- Resource right-sizing, savings plans, and cost management after migration.
- Performance tuning, autoscaling, and storage lifecycle governance.
- Post-migration reviews, optimization roadmaps, and documenting lessons learned.
9. Practical Workshop: Complete Migration Scenario
- Conduct discovery and plan a migration phase for example workloads.
- Replicate a server using MGN and perform a test switchover.
- Transfer a sample database using DMS and verify the results.
- Execute the final switchover, confirm service health, and record the outcomes.
