API Gateway:VPC-based API calls

Access API Gateway from a VPC

API Gateway supports access over the Internet or a VPC:

• Enable VPC-based access for a serverless instance: Serverless instances support VPC-based access. All VPCs in the same region as the instance can access it.

• Enable VPC access for a dedicated instance: You can authorize only one VPC in the same region to access a dedicated instance. Other VPCs in the same region are blocked, which enhances security.

Access API Gateway from Function Compute over an internal network

Function Compute can access API Gateway over a VPC in the following scenarios:

• Scenario 1: API Gateway and Function Compute are deployed in the same region.

• Scenario 2: API Gateway and Function Compute are deployed in different regions.

Configuration rules:

• Access must go through a VPC.
