In this post, we’ll discuss the same thing but this time VPCB and API-VPC are connected using VPC Peering. So we won’t need to create Endpoint Service. Prerequsite: Same as…

In this post, we’ll see how we can use AWS API Gateway as a proxy to our internal application. The API Gateway will be integrated with a Lambda function and when we access our API Gateway’s DNS, this Lambda will redirect the traffic to our internal Application Load Balancers.

Recently we had a requirement to setup connectivity between ECS tasks and ECR repo using VPC Endpoints,so that traffic does not go through Internet/NAT Gateway. You can refer to https://www.easydeploy.io/blog/how-to-create-private-link-for-ecr-to-ecs-containers-to-save-nat-gatewayec2-other-charges/ to accompolish this task. You also need to create endpoint for com.amazonaws.ap-southeast-1.ecr.api which is not mentioned in this article.
