What is Clustering?

With clustering, IT-Components are grouped to act as a single entity, to distribute heavy workload over a set of machinery. The sum of involved components (Nodes) define a cluster’s overall power and provide protection against technical failure. To achieve this the cluster must manage all data required to solve a given task so that every information is available to all nodes at the same time. Most often forming a cluster is done through infrastructure as code principles to ensure a homogenous scalable environment. This can be simply realized in the cloud through numerous instances.
