Configure DC Cluster Group
On This Page:
Objective
This guide provides instructions on how to add a site to a DC cluster group (DCG) using F5® Distributed Cloud Console (Console). For more information on an F5® Distributed Cloud Services Site, see Site.
A DC cluster group represents a collection of sites that can directly communicate with each other using the underlay network. You can use a DC cluster group if your site is using the Ingress/Egress Gateway (Two Interface) or App Stack Cluster (One Interface) options.
DCG Versus SMG
A DCG should be used for cloud sites when the sites are connected over a private backbone. In other words, a Site Mesh Group (SMG) is preferred for public cloud sites, while a DC cluster group is preferred for physical K8s or F5® Distributed Cloud App Stack sites.
An SMG uses IPsec tunnel and a DCG uses IP-in-IP tunnel encapsulation. A DCG will give better performance, while an SMG is more secure.
Prerequisites
The following prerequisites apply:
-
A Distributed Cloud Services Account. If you do not have an account, see Create an Account.
-
One or more Distributed Cloud Services sites deployed. For AWS/Azure/GCP sites, you must enable peering within the same public cloud prior to configuring the DC cluster group. For more information, see documentation:
- AWS VPC Peering: Create a VPC peering connection
- Azure VNet Peering: Tutorial: Connect virtual networks with virtual network peering using the Azure portal
- GCP VPC Network Peering: Use VPC Network Peering
Configuration
