AWS PrivateLink is a networking service that allows private connections between cloud services and virtual networks, enhancing security by keeping network traffic within the cloud provider's network. This connection is made without exposing your data to the public internet, reducing the risk of external threats and minimizing latency. PrivateLinks facilitate uni-directional communication, preventing unauthorized access and data exfiltration. To implement AWS PrivateLink for Couchbase Capella, you need to create a VPC in AWS, launch an EC2 instance, install the AWS CLI tool, and set up a Capella database. You then enable Private Endpoint on your Capella database, add a private endpoint, complete the connection, test the connection using curl commands, and verify that data is being communicated securely between your resources and Couchbase Capella. By establishing a private connection between your VPC and Couchbase Capella, you effectively isolate traffic from the public internet, reducing the risk of exposure to potential threats and ensuring high security and reliability for your data communication.
