This curriculum spans the technical and operational complexity of a multi-phase hybrid cloud migration, comparable to an enterprise advisory engagement that integrates infrastructure assessment, network design, identity federation, data resilience, and cross-environment governance.

Module 1: Assessing On-Premises Infrastructure Readiness

  • Evaluate server utilization metrics to determine which workloads are suitable for cloud migration versus those requiring on-premises retention due to performance or compliance constraints.
  • Inventory legacy applications dependent on specific hardware or unsupported operating systems, and assess refactoring or rehosting options.
  • Analyze network bandwidth and latency between data centers and target cloud regions to identify bottlenecks for hybrid connectivity.
  • Map existing storage subsystems (SAN/NAS) to equivalent cloud storage classes, considering IOPS, durability, and cost implications.
  • Identify dependencies between applications and databases using dependency mapping tools to avoid breaking critical business processes during migration.
  • Conduct security posture assessments of on-premises systems to ensure baseline compliance before establishing hybrid trust boundaries.

Module 2: Designing Hybrid Network Architecture

  • Choose between IPsec VPN and AWS Direct Connect/Azure ExpressRoute based on required throughput, redundancy, and cost tolerance.
  • Implement route propagation policies across on-premises and cloud routers to prevent routing loops and ensure failover consistency.
  • Segment hybrid networks using VLANs and VPC peering to enforce isolation between development, production, and sensitive data environments.
  • Configure DNS resolution across hybrid environments using split-horizon or centralized DNS services to maintain consistent name resolution.
  • Deploy firewall rules at cloud perimeter and on-premises edge to control bidirectional traffic and enforce zero-trust principles.
  • Plan for asymmetric routing scenarios when using multiple connectivity paths and implement monitoring to detect traffic blackholes.

Module 4: Data Synchronization and Latency Management

  • Select between synchronous and asynchronous replication for databases based on RPO and RTO requirements, accepting trade-offs in consistency versus availability.
  • Implement change data capture (CDC) mechanisms to minimize data transfer volume between on-premises and cloud databases.
  • Configure caching layers (e.g., Redis, ElastiCache) near cloud applications to reduce round-trip latency to on-premises data sources.
  • Encrypt data in transit using TLS 1.3 or IPsec, ensuring compatibility with existing PKI infrastructure and certificate rotation policies.
  • Monitor replication lag using native database tools or third-party agents and trigger alerts when thresholds exceed SLA limits.
  • Design fallback procedures for data access during network outages, including local read replicas or cached datasets.

Module 5: Identity and Access Management Integration

  • Extend on-premises Active Directory to the cloud using AD Connect or AWS Managed Microsoft AD, synchronizing users and groups with filtering rules.
  • Map on-premises roles to cloud IAM policies using attribute-based access control, ensuring least privilege is maintained across environments.
  • Implement multi-factor authentication (MFA) enforcement for cloud console and API access without disrupting legacy application service accounts.
  • Configure federation using SAML 2.0 or OIDC between on-premises identity providers and cloud services for single sign-on.
  • Establish audit trails for cross-environment access by forwarding IAM and AD logs to a centralized SIEM platform.
  • Define lifecycle management procedures for deprovisioning access when employees leave, covering both on-premises and cloud systems.

Module 6: Governance, Compliance, and Cost Control

  • Apply tagging standards across hybrid resources to enable cost allocation, security classification, and automated policy enforcement.
  • Implement cloud governance policies using Azure Policy or AWS Config to restrict region usage, instance types, and unapproved services.
  • Conduct regular compliance audits to verify adherence to data residency laws, especially when data crosses geographic boundaries.
  • Set up budget alerts and reservation planning for cloud services to prevent cost overruns while maintaining performance SLAs.
  • Define ownership models for hybrid resources, assigning accountability for patching, monitoring, and configuration drift.
  • Establish change control processes that require approval for modifications to core hybrid networking or identity components.

Module 7: Disaster Recovery and Failover Planning

  • Define recovery site strategies by selecting active-passive or active-active configurations based on application criticality and budget.
  • Test failover procedures for hybrid workloads using controlled network partitioning to simulate data center outages.
  • Configure automated backups of on-premises systems to cloud storage with lifecycle policies to manage retention and cost.
  • Validate RTO and RPO through documented runbooks and timed recovery exercises involving both cloud and on-premises teams.
  • Replicate critical VMs using VMware HCX or Azure Site Recovery, ensuring compatibility with target cloud hypervisors.
  • Document manual intervention steps for scenarios where automated failover fails due to authentication or network configuration issues.

Module 8: Monitoring, Logging, and Operational Continuity

  • Deploy unified monitoring agents across on-premises and cloud hosts to collect metrics in a single observability platform like Datadog or Splunk.
  • Correlate logs from firewalls, domain controllers, and cloud services using centralized log aggregation with consistent timestamping.
  • Define alert thresholds for hybrid-specific issues such as tunnel downtime, replication lag, or identity sync failures.
  • Implement synthetic transactions to proactively test end-to-end functionality across hybrid application paths.
  • Standardize runbook automation for common incidents like failed connectivity or authentication timeouts using tools like Ansible or Azure Automation.
  • Conduct cross-team incident response drills to ensure coordination between on-premises operations and cloud platform teams during outages.
