= Strimzi operators

[role="_abstract"]
Strimzi operators are purpose-built with specialist operational knowledge to effectively manage Kafka on Kubernetes.
Each operator performs a distinct function.

Cluster Operator:: The Cluster Operator handles the deployment and management of Apache Kafka clusters on Kubernetes. 
It automates the setup of Kafka brokers, and other Kafka components and resources.
Topic Operator:: The Topic Operator manages the creation, configuration, and deletion of topics within Kafka clusters. 
User Operator:: The User Operator manages Kafka users that require access to Kafka brokers. 

When you deploy Strimzi, you first deploy the Cluster Operator.
The Cluster Operator is then ready to handle the deployment of Kafka.
You can also deploy the Topic Operator and User Operator using the Cluster Operator (recommended) or as standalone operators.
You would use a standalone operator with a Kafka cluster that is not managed by the Cluster Operator.

The Topic Operator and User Operator are part of the Entity Operator.
The Cluster Operator can deploy one or both operators based on the Entity Operator configuration.

[IMPORTANT]
====
To deploy the standalone operators, you need to set environment variables to connect to a Kafka cluster.
These environment variables do not need to be set if you are deploying the operators using the Cluster Operator as they will be set by the Cluster Operator.
