This curriculum spans the equivalent of a multi-workshop technical engagement, addressing the full lifecycle of cloud migration with the depth required to guide architectural decisions, coordinate cross-functional teams, and manage operational transitions in complex enterprise environments.
Module 1: Assessing Application Readiness for Cloud Migration
- Evaluate legacy application dependencies on on-premises infrastructure such as local databases, file shares, or hardware security modules.
- Determine whether to refactor monolithic applications into microservices based on business criticality and technical debt.
- Classify applications by migration priority using criteria like downtime tolerance, compliance requirements, and user impact.
- Decide whether to retire, rebuild, or rehost applications based on vendor support, code maintainability, and integration complexity.
- Conduct performance baselining of current on-premises workloads to establish cloud performance benchmarks.
- Engage application owners to validate functionality and data consistency post-migration during proof-of-concept testing.
Module 2: Selecting Migration Strategies and Target Architectures
- Choose between rehost (lift-and-shift), refactor, rearchitect, or replace based on time-to-market constraints and long-term TCO.
- Design target cloud architectures that align with native services (e.g., serverless, managed databases) without introducing vendor lock-in.
- Map existing network topology to cloud VPCs, subnets, and routing requirements while preserving security segmentation.
- Decide whether to adopt multi-cloud or single-cloud strategies based on regulatory jurisdiction and failover needs.
- Integrate identity federation with existing enterprise directories while minimizing authentication latency in hybrid scenarios.
- Balance use of Infrastructure-as-Code (IaC) tools (e.g., Terraform, AWS CloudFormation) against team expertise and deployment velocity.
Module 3: Data Migration Planning and Execution
- Estimate data transfer time and cost using available bandwidth, compression, and staging strategies like offline appliances.
- Define cutover windows for database migration based on transaction volume and acceptable data lag.
- Implement data consistency checks between source and target systems using checksums or row-count validation.
- Handle personally identifiable information (PII) during migration by applying encryption in transit and at rest.
- Decide between homogeneous and heterogeneous database migrations based on licensing, performance, and support lifecycle.
- Orchestrate batch data syncs and CDC (Change Data Capture) replication to minimize downtime during final cutover.
Module 4: Network and Connectivity Configuration
- Configure hybrid connectivity via Direct Connect or ExpressRoute based on latency, throughput, and redundancy requirements.
- Implement DNS failover and traffic routing strategies during migration using Route 53 or Azure Traffic Manager.
- Size and deploy cloud firewalls and web application gateways to match existing on-premises throughput and inspection rules.
- Segment migrated workloads using cloud-native security groups and network ACLs aligned with zero-trust principles.
- Establish secure peering between VPCs/VNets across regions or accounts while avoiding transitive routing pitfalls.
- Monitor network performance post-migration to detect packet loss, jitter, or routing inefficiencies affecting application behavior.
Module 5: Security, Compliance, and Identity Management
- Map on-premises role-based access controls (RBAC) to cloud IAM policies while minimizing privilege creep.
- Integrate cloud workloads with centralized SIEM systems for log aggregation and threat detection continuity.
- Enforce encryption standards for data at rest using customer-managed or cloud-provider keys based on regulatory mandates.
- Conduct compliance gap analysis for frameworks such as HIPAA, SOC 2, or GDPR before migrating regulated workloads.
- Implement automated policy checks using CSPM tools to detect non-compliant configurations during deployment.
- Rotate and manage secrets (e.g., API keys, database passwords) using cloud-native secret managers or HashiCorp Vault.
Module 6: Automation and DevOps Pipeline Integration
- Integrate migration artifacts into CI/CD pipelines to enable repeatable, auditable deployment of cloud environments.
- Standardize configuration drift detection using drift monitoring tools tied to IaC templates.
- Automate rollback procedures for failed migrations using pre-defined snapshot and backup triggers.
- Containerize applications for portability and faster deployment, weighing image size against startup time.
- Orchestrate migration waves using pipeline stages that include smoke testing and health checks.
- Version control all infrastructure definitions and associate changes with ticketing systems for auditability.
Module 7: Cutover Execution and Production Validation
- Define and communicate cutover checklists that include DNS updates, firewall rule activation, and service restarts.
- Execute final data sync and validate referential integrity before redirecting user traffic.
- Monitor application health metrics (latency, error rates, CPU) immediately after cutover to detect anomalies.
- Coordinate rollback decisions with business stakeholders based on predefined SLA thresholds and user feedback.
- Validate end-to-end business processes with key users or automated synthetic transactions post-migration.
- Document lessons learned from cutover execution to refine future migration runbooks.
Module 8: Post-Migration Optimization and Governance
- Right-size compute instances based on actual utilization metrics collected during the first 30 days in production.
- Implement cost allocation tags across resources and integrate with financial reporting systems for chargeback.
- Establish ongoing performance baselines and alerting thresholds tailored to cloud workload behavior.
- Review and update disaster recovery runbooks to reflect new cloud-based failover mechanisms.
- Conduct architecture reviews to identify opportunities for further optimization using managed services.
- Formalize operational handover to cloud operations teams with documented SLAs, escalation paths, and monitoring coverage.
