Google Distributed Cloud supports two load balancer options: bundled and manual.
Bundled load balancer mode
If you choose bundled load balancing, Google Distributed Cloud deploys L4 load balancers
during cluster installation. An external load balancer is not needed. The load
balancers can run on a dedicated pool of worker nodes or they can be located on
the same nodes as the control plane.
All nodes that run load balancers must be on the same L2 subnet because load
balancers broadcast
ARP
messages to announce VIPs.
The following diagram shows an example network topology where bundled load
balancers are located on the control plane nodes.
Manual load balancer mode
If you choose manual load balancing, Google Distributed Cloud does not deploy load
balancers. This allows more flexibility than bundled load balancing and there
are no L2 network requirements.
You must configure your control plane nodes' VIPs on an external load
balancer before installing the cluster. After installation, you must pick a load
balancing solution for Kubernetes Services and Ingresses.
The following diagram shows an example network topology of a cluster using
manual load balancing mode with an external load balancer.
