Amazon API Gateway REST APIs now supports private integration with Application Load Balancer

Amazon API Gateway REST APIs

Now support direct private integration with Application Load Balancer (ALB), enabling inter-VPC connectivity to internal ALBs. This enhancement extends API Gateway's existing VPC connectivity, providing more flexible and efficient architecture choices for your REST API implementations.

Advantages

• Reduced latency by eliminating the additional network hop previously required through Network Load Balancer.
• Lower infrastructure costs through simplified architecture.
• Enhanced Layer 7 capabilities including HTTP/HTTPS health checks, advanced request-based routing, and native container service integration.

You can still use API Gateway's integration with Network Load Balancers for layer-4 connectivity.
