Cluster

A cluster is a group of computers or servers that work together as a single system. Clusters allow for greater performance, scalability, and reliability compared to a single computer.

In cloud computing and devops, clusters are commonly used to deploy applications and services. For example, a web application may run on a cluster of servers to handle large amounts of web traffic and requests. If one server fails, the application continues running on the other servers in the cluster. Clusters can easily scale out by adding more servers to meet demand. Cloud providers like AWS, Azure, and GCP provide managed cluster services like Kubernetes to deploy containerized applications across a cluster. Kubernetes handles tasks like load balancing and health monitoring to maintain high availability of applications running on the cluster. Developers and devops engineers utilize clusters and container orchestrators like Kubernetes to easily deploy, manage, and scale their applications in the cloud.
