What are Operators?

API Extension

Extend Kubernetes API with custom resources and controllers.

State Management

Manage complex application state and lifecycle automatically.

Automation

Application Types & Operator Usage

Stateless Applications

Low

Simple applications that don't require complex state management.

Examples: Web Applications, APIs
Usually not needed

Stateful Applications (without Operator)

Medium

Complex applications managed manually or with basic K8s resources.

Examples: Databases, Message Queues
Manual intervention required

Stateful Applications (with Operator)

High

Complex applications managed automatically by operators.

Examples: Clustered Databases, Distributed Systems
Fully automated
