How do we launch a cluster in AWS VPC?

You can read about Amazon VPC and VCP peering to CloudAMQP in this blog post.

Dedicated VPC is only available as an extra option for our dedicated plans, for $99. A dedicated plan is Big Bunny or any plan larger than Big Bunny. Select to create your cluster in a dedicated VPC. When you create your VPC you get to select the VPC subnet, make sure that it does not overlap with any VPC subnets you want to peer with.

Open the details for your new instance as soon as it is created and navigate to the tab VPC Peering. Enter your AWS Account ID and your VPC ID and Press save. CloudAMQP will now request to set up a VPC connection to you.

The request can be accepted from the Amazon VPC console at https://console.aws.amazon.com/vpc/
