High-availability

How to increase the uptime of your workload clusters by using multiple availability zones for worker nodes, or using control plane nodes in several availability zones.

• High-availability control plane
  For production clusters with high availability requirements, Giant Swarm on AWS enables control planes with three control plane nodes and three etcd replicas spread over multiple availability zones.
• Multiple AZ
  Using multiple availability zones both for worker and control plane nodes increases the resilience of the cluster. Here we explain some details regarding support on different cloud providers and releases, plus how to configure workloads to leverage multiple availability zones.
