Pattern 1

Multi-Account Landing Zone

AWS Control Tower with customized guardrails, organizational units for workload isolation, and centralized logging via a dedicated security account. This pattern supports SOC 2 and FedRAMP compliance requirements by enforcing account-level separation between production, staging, development, and shared services workloads. Service Control Policies restrict region usage and deny root account access across all member accounts.

Pattern 2

Hub-Spoke Network Topology

Transit Gateway as the central hub connecting VPC spokes, with shared services (DNS, NTP, patching) in a dedicated hub VPC. Route table segmentation prevents spoke-to-spoke communication unless explicitly allowed. This pattern scales to 50+ VPCs while maintaining centralized firewall inspection via AWS Network Firewall or third-party NVAs deployed in the inspection VPC.

Pattern 3

Hybrid Connectivity with Direct Connect

Dual Direct Connect connections in active/passive configuration with VPN as tertiary failover. BGP routing with AS path prepending for traffic engineering, and private VIF for VPC access plus transit VIF for cross-region connectivity. MACsec encryption enabled on the physical connections for wire-level security between on-premises data centers and AWS regions.
