In order to provision cloud clusters, you must first deploy a base set of infrastructure into your CSP account. Throughout our documentation, we refer to this as the base infrastructure. This base infrastructure is shared by multiple clusters and varies for each CSP. In essence, you can think of it as the networking stack which clusters will be deployed on top of.
Below, you can find specific details about the implementation of this base infrastructure for each CSP.
Deploying base infrastructure provisions the following on AWS:
The schematic below shows an ACTIVATE-deployed cluster in AWS Cloud.
The controller and compute nodes are shown in Availability Zone us-east-1a inside the us-east-1 Region. When using the default networking mode, compute nodes in a region use a single NAT gateway for outbound internet connectivity. This NAT gateway is pre-provisioned as part of the base infrastructure. The AMI used for the controller and compute nodes is inside the Parallel Works AWS account.
Expense Information
Depending on the networking mode, a NAT gateway will be created resulting in an additional monthly charge in your AWS account. For more information, please see this AWS pricing list.
