One of the most asked questions we receive from new Couchbase Capella cluster users is how do I set up and connect to the fully managed service. Communication between your application and the internet-hosted cluster is trivial, but connecting over a private network is more challenging. The need to connect over a private network from your AWS VPC to Couchbase\u2019s VPC will become ever more critical for high-performing mission-critical applications.<\/span><\/p>\n

Setting up <\/span>VPC Peering <\/b>requires a small amount of work on both sides of the network. There is detailed documentation on the Couchbase <\/span>website<\/span><\/a>. However, we hope this step-by-step walkthrough will make things a little easier for the first-time user. We will go from having neither of the VPCs set up and building from scratch. Understandably, an application\u2019s VPC may already be configured and not follow all these steps, but the walkthrough should at least give you some insight into the process.<\/span><\/p>\n

Creating a Couchbase Capella cluster on AWS<\/span><\/h2>\n

Ideally, people would already have experience spinning up a Couchbase Capella database at this point. If not, head to <\/span>cloud.couchbase.com<\/span><\/a> and either sign up for a free trial or launch a new cluster with whichever specifications you need.<\/span><\/p>\n

There are two essential aspects to bear in mind when creating your cluster. First, the region where you deploy your cluster should match the VPS AWS region you are using.<\/span><\/p>\n

Next, the CIDR Block of your deployed cluster <\/span>MUST be different <\/span><\/i>from the AWS VPC. Take note of the CIDR block <\/span>before you click<\/span><\/i> Deploy<\/b>. If your AWS VPC already exists with a CIDR block, you can customize Capella to avoid duplication.<\/span><\/p>\n

Creating a VPC in AWS<\/span><\/h2>\n

We will create a new VPC from scratch in this walkthrough; however, as stated before, your VPC may already exist. If so, then just ensure that it follows these guidelines.<\/span><\/p>\n

Head over to the <\/span>VPC <\/b>section of the AWS management console and select <\/span>Create VPC.<\/b><\/p>\n
