AWS Serverless Application Repository now supports AWS PrivateLink to connect to AWS Serverless Application Repository through an interface VPC endpoint. You can now connect directly to the AWS Serverless Application Repository using AWS PrivateLink in your virtual private cloud (VPC) instead of connecting over the internet.
When you use an AWS PrivateLink, communication between your VPC and AWS Serverless Application Repository is conducted entirely within the AWS network, which can provide greater security and protect your sensitive information. An AWS PrivateLink endpoint connects your VPC directly to AWS Serverless Application Repository. The instances in your VPC don’t need public IP addresses to communicate with the AWS Serverless Application Repository API. To use AWS Serverless Application Repository through your VPC, you have two options. One is to connect from an instance that is inside your VPC. The other is to connect your private network to your VPC by using an AWS VPN option or AWS Direct Connect. You can create an AWS PrivateLink to connect to AWS Serverless Application Repository using the AWS Management Console or AWS Command Line Interface (AWS CLI) commands. For more information, see Creating an Interface Endpoint.
AWS Serverless Application Repository support for AWS PrivateLink is available in all AWS regions where AWS Serverless Application Repository is available.
