= Provisioned {gcp-short} Infrastructure
|

|
|
[role="_abstract"]
|
|
This is an overview of the provisioned {gcp-first} components on a deployed {product-title} cluster. For a more detailed listing of all provisioned {gcp-short} components, see the link:https://access.redhat.com/documentation/en-us/openshift_container_platform/[{OCP} documentation].

== Compute instances
|
|
|
|
{gcp-short} compute instances are required to deploy the control plane and data plane functions of {product-title} in {gcp-short}. Instance types might vary for control plane and infrastructure nodes depending on worker node count.
|
|
|
|
* Single availability zone
|
|
** 2 infra nodes (n2-highmem-4 machine type: 4 vCPU and 32 GB RAM)
|
|
** 3 control plane nodes (n2-standard-8 machine type: 8 vCPU and 32 GB RAM)
|
|
** 2 worker nodes (default n2-standard-4 machine type: 4 vCPU and 16 GB RAM)
|
|
* Multiple availability zones
|
|
** 3 infra nodes (n2-highmem-4 machine type: 4 vCPU and 32 GB RAM)
|
|
** 3 control plane nodes (n2-standard-8 machine type: 8 vCPU and 32 GB RAM)
|
|
** 3 worker nodes (default n2-standard-4 machine type: 4 vCPU and 16 GB RAM)

|
== Storage
|
|
|
|
* Infrastructure volumes:
|
|
** 300 GB SSD persistent disk (deleted on instance deletion)
|
|
** 110 GB Standard persistent disk (kept on instance deletion)
|
|
* Worker volumes:
|
|
** 300 GB SSD persistent disk (deleted on instance deletion)
|
|
* Control plane volumes:
|
|
** 350 GB SSD persistent disk (deleted on instance deletion)

== VPC
|
|
|
|
include::snippets/snip_install-cluster-in-vpc.adoc[]
|
|
|
|
* **Subnets:** One master subnet for the control plane workloads and one worker subnet for all others. An additional subnet is required for Google Private Service Connect (PSC) when a private cluster is deployed using PSC.
|
|
* **Router tables:** One global route table per VPC.
|
|
* **Internet gateways:** One internet gateway per cluster.
|
|
* **NAT gateways:** One master NAT gateway and one worker NAT gateway per cluster.
