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.
