Availability refers to the ability of the user to access the service or system. The high availability of a system ensures an agreed level of uptime of the system. For example, if there is only one instance to serve the service and the instance is down, users can no longer access the service. A service with high availability is served by multiple instances. When one instance is down, the standby instance or backup instance can still provide the service. The following diagram describes services with and without high availability:

Figure 11.1 – Services with and without high availability

In a Kubernetes cluster, there will usually be more than one worker node. The high availability of the cluster is guaranteed as even if one worker node is down, there are some other worker nodes to host the workload. However, high availability is more than running multiple nodes in the cluster. In this section, we will...
