Apache Ambari Architecture

Ambari provides intuitive and REST APIs that automate operations in the Hadoop cluster. Its consistent and secure interface allows it to be fairly efficient in operational control. Its easy and user-friendly interface efficiently diagnoses the health of the Hadoop cluster using an interactive dashboard.

To have a better understanding of how Ambari works, let’s look at the detailed architecture of Apache Ambari in the following diagram:

Apache Ambari follows a master–slave architecture where the master node instructs the slave nodes to perform certain actions and report back the state of every action. The master node is responsible for keeping track of the state of the infrastructure. To do this, the master node uses a database server, which can be configured during the setup time.
