With ClusterControl gaining in popularity, we are seeing users coming in from different angles. Some users are deploying their database cluster using our Online Configurators, others are looking to install ClusterControl to manage an existing database cluster. And some other users prefer to install ClusterControl first, and then use it to deploy database clusters on-premises.
In this blog post, we will cover the different options.
Let’s go through some basics first. ClusterControl consists of two components:
- ClusterControl Server (deployed on ClusterControl host) - this is the controller that automates all the management procedures on the database cluster. ClusterControl provides a modern Web UI to visualize the cluster and schedule tasks like backup, configuration changes, upgrades, etc.
- ClusterControl agents (deployed on database hosts) - lightweight agents that monitor and report host and database status to the controller. All monitoring data is stored on the ClusterControl Server’s database.
Note that each cluster needs a dedicated local ClusterControl host. For users with multiple database clusters, it is possible to have a dedicated host for a centralized ClusterControl server to monitor and manage your clusters.
** The number of minimum servers for each database cluster type has been illustrated in the above diagram.
