Who Are Cloud Migration Specialists
Cloud migration specialists help organizations move applications, databases, and workloads from on-prem or other clouds into AWS, Azure, or GCP. Their expertise covers assessment, planning, execution, and cutover.
Typical responsibilities include:
- Dependency discovery and app mapping.
- Designing landing zones, networking, and identity foundations.
- Selecting the right migration strategy (rehost, replatform, refactor).
- Executing large-scale VM/application/database migrations.
- Validating performance and security post-migration.
They ensure migrations happen smoothly, securely, and with minimal downtime.
Questions to Ask Before Hiring a Cloud Migration Specialist
- What types of workloads have you migrated (VMs, databases, ERP, containers)?
- How do you assess application readiness and dependencies?
- Which migration strategies do you recommend for different app types?
- How do you manage cutover, rollback, and testing?
- What landing zone standards do you follow (networking, IAM, security)?
- How do you ensure minimal downtime during the transition?
- What documentation and post-migration support do you provide?
Migration Strategy Matrix
Cloud migration specialists build a strategy matrix to select the best approach per workload:
- Rehost (“Lift and Shift”): fastest, minimal changes, good for legacy VMs.
- Replatform: move to managed database/services while keeping core architecture.
- Refactor: modify the application to run cloud-natively (microservices, containers).
- Repurchase: replacing legacy systems with SaaS equivalents.
- Retire: eliminating unused or unnecessary applications.
- Retain: keeping workloads on-prem if migration is not beneficial.
This matrix ensures each application migrates using the most efficient and least risky path.
Cloud Cutover & Validation Checklist
A successful migration ends with a clean cutover and validation. Specialists typically oversee:
- DNS & Networking Switch: routing traffic to cloud environments.
- Load Testing: verifying performance under production-level usage.
- Data Validation: checking replication integrity and database accuracy.
- Security Validation: confirming IAM, firewalls, and encryption settings.
- Rollback Procedures: ensuring a safe exit plan if issues arise.
- Monitoring Setup: enabling metrics, logging, and health checks.
- Post-Cutover Stabilization: resolving issues in the first 24–72 hours.
This ensures migrated workloads operate correctly, securely, and without downtime.
