This curriculum spans the technical and operational rigor of a multi-workshop cloud migration engagement, addressing network assessment, hybrid design, security integration, application refactoring, and cross-cloud governance as typically encountered in large-scale enterprise transformations.

Module 1: Assessing On-Premises Network Readiness for Cloud Migration

  • Evaluate existing WAN bandwidth utilization across business-critical applications to determine baseline capacity requirements for cloud connectivity.
  • Inventory legacy protocols (e.g., SNA, IPX) and non-TCP/IP dependencies that may not be supported in cloud environments.
    • Identify firewall rule sets and stateful inspection policies that must be replicated or redesigned for cloud on-ramps.
  • Conduct latency profiling between primary data centers and target cloud regions to assess suitability for latency-sensitive applications.
  • Map application dependencies using packet capture and flow analysis tools to define secure communication paths in hybrid topology.
  • Assess DNS architecture for split-horizon requirements and plan for integration with cloud provider DNS services.

Module 2: Designing Hybrid Connectivity Architectures

  • Select between IPsec VPN and dedicated private connections (e.g., AWS Direct Connect, Azure ExpressRoute) based on compliance, cost, and performance thresholds.
  • Define BGP routing policies for route advertisement, prefix filtering, and failover behavior between on-premises and cloud VPCs/VNets.
  • Design multi-region transit gateway architectures to enable cloud-to-cloud and hub-spoke communication patterns.
  • Implement asymmetric routing controls using route tables and security groups to prevent traffic black-holing in hybrid paths.
  • Size and provision redundant cross-connects at colocation facilities to meet SLA uptime requirements for private links.
  • Integrate SD-WAN edge devices with cloud provider virtual gateways to enable dynamic path selection and application steering.

Module 3: Securing Cloud Network Perimeters

  • Deploy cloud-native firewall instances (e.g., Palo Alto VM-Series, FortiGate-VM) in forced tunneling topologies for egress inspection.
  • Enforce mutual TLS or IPsec between on-premises workloads and cloud microservices in zero-trust segmentation models.
  • Configure network ACLs and security groups to follow least-privilege principles, avoiding overly permissive /32 or /0 rules.
  • Implement DDoS protection at the cloud edge using provider-managed services (e.g., AWS Shield Advanced, Azure DDoS Protection) with traffic scrubbing.
  • Integrate cloud firewall logs with on-premises SIEM using secure log forwarding with TLS encryption and authentication.
  • Apply geo-fencing rules at the perimeter to block inbound traffic from high-risk jurisdictions based on threat intelligence feeds.

Module 4: Migrating and Refactoring Network-Dependent Applications

  • Reconfigure stateful applications (e.g., legacy ERP) to operate within cloud-enforced ephemeral IP constraints using DNS or load balancer abstractions.
  • Modify application code or middleware to replace hardcoded IP addresses with service discovery mechanisms (e.g., Consul, cloud DNS).
  • Adjust TCP keepalive and session timeout settings to align with cloud load balancer idle connection thresholds.
  • Re-architect multicast-dependent applications using unicast replication or message queues compatible with cloud networking.
  • Validate application behavior under variable cloud network latency using packet delay and jitter injection in staging environments.
  • Coordinate cutover windows with ISP and cloud provider support teams to minimize disruption during DNS TTL expiration and failover.

Module 5: Managing DNS, DHCP, and IP Addressing in Hybrid Environments

  • Deploy split DNS zones to resolve internal hostnames differently for on-premises versus cloud-resident clients.
  • Implement IPAM (IP Address Management) tools to track overlapping RFC 1918 address spaces across on-prem and cloud VPCs.
  • Configure DHCP relay agents to forward requests from cloud subnets to on-premises DHCP servers where centralized leasing is required.
  • Automate private IP assignment in cloud environments using Terraform or cloud-native deployment templates with reserved ranges.
  • Plan VPC/VNet CIDR blocks to avoid overlap with existing corporate subnets and accommodate future expansion.
  • Migrate static IP workloads using elastic IPs or cloud provider NAT gateways to preserve external connectivity during transition.

Module 6: Monitoring, Troubleshooting, and Performance Optimization

  • Deploy cloud-native flow logging (e.g., VPC Flow Logs, Azure Network Watcher) with aggregation to centralized storage for traffic analysis.
  • Establish synthetic transaction monitoring from on-premises to cloud endpoints to detect latency spikes or packet loss.
  • Use packet capture tools (e.g., tcpdump on EC2, Azure Packet Capture) to diagnose asymmetric routing or MTU mismatches.
  • Correlate BGP session state changes with application availability incidents using time-synchronized logging.
  • Baseline normal egress bandwidth consumption to detect data exfiltration or misconfigured backup jobs.
  • Implement active path monitoring using bidirectional forwarding detection (BFD) for rapid failover on private connections.

Module 7: Governance, Compliance, and Operational Handover

  • Define ownership model for hybrid network components, specifying accountability for cloud routing tables versus on-prem BGP peers.
  • Enforce network configuration standards using policy-as-code tools (e.g., AWS Config, Azure Policy) with automated non-compliance alerts.
  • Document network topology, failover procedures, and contact lists for incident response involving hybrid connectivity.
  • Conduct tabletop exercises simulating private link failure to validate runbooks and escalation paths.
  • Archive pre-migration network configurations and firewall rules for audit and rollback purposes.
  • Integrate cloud network operations into existing NOC workflows, including alerting thresholds and on-call rotation alignment.

Module 8: Planning for Scalability and Multi-Cloud Networking

  • Design cloud network architecture with modular subnets to support application scaling without re-IPing.
  • Implement centralized routing registries to manage inter-VPC and inter-cloud peering relationships.
  • Evaluate cloud provider interconnect services (e.g., Google Cloud Interconnect, AWS Transit Gateway) for multi-region scalability.
  • Standardize network tagging conventions across cloud platforms to enable consistent cost allocation and policy enforcement.
  • Assess bandwidth requirements for data replication between cloud providers in active-active disaster recovery configurations.
  • Negotiate peering agreements with cloud providers for direct inter-cloud connectivity to reduce egress costs and latency.
