Fine-Tuning Control Plane Access with Cluster API

Scott Lowe

When Cluster API creates a workload cluster, it also creates a load balancing solution to handle traffic to the workload cluster’s control plane. For flexibility, Cluster API provides a limited ability to customize this control plane load balancer. If you specify “internal” as the scheme, then the load balancer won’t get a public IP address and won’t be reachable via the Internet.

With those assumptions and that caveat in mind, the high-level overview of the process looks like this: Create a load balancer for the control plane. Create a Load Balancer for the Control Plane. The first step is to create a load balancer for the control plane (a load balancer is required when using multiple control plane nodes). As I mentioned earlier, the use of a DNS CNAME for the control plane load balancer is recommended.).

Looking back at 10 years of compartmentalization at AWS

All Things Distributed

By using zones, and failover mechanisms such as Elastic IP addresses and Elastic Load Balancing, you can provision your infrastructure with redundancy in mind. The calls used to launch and manage EC2 instances, fail over an RDS instance, or handle the health of instances behind a load balancer, all work within one zone. At AWS, we don't mark many anniversaries.
