This curriculum spans the technical and operational rigor of a multi-workshop cloud migration program, addressing the same workload classification, network topology, identity governance, and cutover planning decisions faced during enterprise advisory engagements.

Module 1: Cloud Readiness Assessment and Application Portfolio Analysis

  • Conduct application dependency mapping to identify inter-service communication patterns that impact migration sequencing.
  • Classify workloads using the Gartner five-quadrant model (rehost, refactor, revise, rebuild, replace) based on technical debt and business criticality.
  • Evaluate licensing constraints for third-party software in cloud environments, particularly for database and security tools with on-premises licensing models.
  • Assess data gravity by measuring volume, latency sensitivity, and residency requirements to determine optimal migration candidates.
  • Perform TCO modeling that includes egress fees, idle resource costs, and support overhead under variable cloud pricing models.
  • Engage business unit stakeholders to align migration timelines with product release cycles and avoid operational disruption.

Module 2: Cloud Architecture Design and Pattern Selection

  • Select between hub-and-spoke and mesh network topologies in multi-account cloud environments based on compliance scope and traffic volume.
  • Implement immutable infrastructure patterns using infrastructure-as-code (IaC) templates to eliminate configuration drift in production.
  • Choose between serverless compute and container orchestration based on workload predictability and cold-start tolerance.
  • Design cross-region failover mechanisms that account for DNS propagation delays and database replication lag.
  • Integrate private service connectivity (e.g., AWS PrivateLink, Azure Private Endpoint) to avoid public exposure of backend systems.
  • Define tagging standards for cost allocation, security classification, and operational ownership at the resource level.

Module 3: Identity, Access, and Privilege Management

  • Implement just-in-time (JIT) privileged access using PAM solutions integrated with cloud IAM to reduce standing privileges.
  • Map on-premises Active Directory groups to cloud roles using attribute-based or claim-based federation with SAML or SCIM.
  • Enforce least privilege by analyzing CloudTrail or Audit Logs to downsize over-provisioned IAM policies using policy simulation tools.
  • Establish cross-account IAM roles with boundary policies to prevent privilege escalation in multi-account landing zones.
  • Configure conditional access policies based on IP ranges, device compliance, and MFA status for administrative console access.
  • Rotate long-lived access keys automatically using scheduled Lambda functions or equivalent serverless automation.

Module 4: Data Migration and Database Modernization

  • Use AWS DMS, Azure Data Migration Service, or equivalent to perform heterogeneous migrations with minimal downtime.
  • Decide between online cutover and phased replication based on transaction volume and acceptable data lag thresholds.
  • Encrypt data at rest using customer-managed keys (CMKs) and validate key rotation policies across regions and accounts.
  • Refactor monolithic databases into microservices-aligned data stores while maintaining referential integrity during transition.
  • Implement change data capture (CDC) pipelines to synchronize on-premises and cloud databases during migration windows.
  • Optimize read replicas placement to balance performance needs against cross-availability zone data transfer costs.

Module 5: Network Integration and Connectivity Strategy

  • Size Direct Connect or ExpressRoute circuits based on peak application throughput and burst requirements.
  • Configure DNS resolution between on-premises and cloud using hybrid forwarders or split-horizon DNS.
  • Implement secure hybrid connectivity using IPsec VPNs with IKEv2 and perfect forward secrecy for failover paths.
  • Design VPC peering or transit gateway routing tables to avoid asymmetric routing and black-holing.
  • Enforce network segmentation using security groups and NACLs aligned with zero-trust zoning principles.
  • Monitor latency and packet loss across hybrid links using synthetic transactions and automated alerting.

Module 6: Security, Compliance, and Governance Enforcement

  • Deploy cloud-native configuration monitoring (e.g., AWS Config, Azure Policy) to detect and auto-remediate non-compliant resources.
  • Integrate cloud logging streams into SIEM platforms with parsing rules tailored to cloud provider schema formats.
  • Enforce encryption mandates using SCPs or Azure Blueprints to block unencrypted storage creation.
  • Conduct periodic access certification reviews for cloud roles, particularly for contractors and temporary staff.
  • Map regulatory controls (e.g., HIPAA, GDPR) to specific technical configurations in cloud environments.
  • Establish incident response playbooks specific to cloud events such as S3 bucket exposure or unauthorized API calls.

Module 7: Cost Management and Operational Sustainability

  • Negotiate enterprise discount programs (e.g., AWS Enterprise Discount Program, Azure Commitment Tiers) based on projected usage.
  • Implement automated shutdown policies for non-production environments using scheduling tags and Lambda functions.
  • Right-size compute instances by analyzing CloudWatch or Azure Monitor metrics over 14-day utilization baselines.
  • Use reserved instances or savings plans strategically, balancing long-term commitments against workload volatility.
  • Tag all resources systematically to enable chargeback reporting by department, project, and cost center.
  • Establish FinOps practices with cross-functional teams to review monthly spend anomalies and optimize allocation.

Module 8: Migration Execution and Cutover Management

  • Define cutover windows in coordination with business operations, considering time zones and customer impact.
  • Validate backup and rollback procedures prior to cutover using point-in-time recovery tests on staging environments.
  • Execute smoke tests immediately post-migration to verify DNS resolution, authentication, and core transaction paths.
  • Monitor application performance post-migration using APM tools to detect latency spikes or error rate increases.
  • Communicate migration status to stakeholders using real-time dashboards with health metrics and incident logs.
  • Decommission on-premises systems only after confirming data consistency and completing a 30-day observation period.
