Application Containerization

Common Challenges & Technical Drivers

• Fears of extended production downtime, data loss, or customer disruption during cutover.
• Hidden dependencies between legacy applications, background jobs, and on-premise hardware.
• Bandwidth bottlenecks causing slow data replication and prolonged synchronization delays.
• Post-migration performance drops caused by misconfigured cloud storage or network throughput.

What Is Included (In-Scope Deliverables)

• Migration discovery, dependency mapping, and workload classification (6 Rs framework).
• Automated continuous data replication (CDC) setup to synchronize data deltas with near-zero lag.
• Target cloud landing zone provisioning and infrastructure validation testing.
• Execution of simulated dry-run cutover and production cutover coordination with roll-back gates.

Scope Boundaries & Transparent Exclusions

• Bandwidth transit costs and destination cloud storage consumption fees.
• Rewriting legacy application source code to cloud-native microservices (covered in Dept 09).
• Decommissioning physical on-premise server hardware or lease negotiations.
• Resolving pre-existing database corruption present on the source system.

Tangible Engineering Deliverables

• Comprehensive Migration Strategy document with phased wave schedules and risk assessments.
• Automated replication pipeline scripts and data validation checksum reports.
• Minute-by-minute cutover runbook with clear rollback triggers and escalation paths.
• Post-migration acceptance audit report verifying performance baselines and data integrity.
