AWS Cloud Connectivity Patterns for Financial Market Infrastructures

This article presents four connectivity patterns for securely integrating AWS workloads with Financial Market Infrastructures (FMIs) in regulated environments.

• Pattern 1: Customer-managed routers with AWS Direct Connect for maximum control
• Pattern 2: FMI-managed routers with hosted connections reducing operational overhead
• Pattern 3: AWS PrivateLink endpoint services eliminating hybrid connectivity infrastructure
• Pattern 4: AWS Resource Gateway enabling FMI-initiated connectivity to customer resources
• Each pattern balances operational complexity, control, and cost differently
• Security includes encryption in transit, security groups, NACLs, and IAM policies
• Patterns support compliance requirements like DORA and PCI DSS

Organizations can adopt patterns matching their cloud maturity level and evolve connectivity strategies over time using managed AWS services instead of traditional on-premises infrastructure.
