A clear and concise title that describes the system and its purpose.

Summary:

A brief overview of the system, including its purpose, key features, and the problem it's intended to solve.

Table of contents

• Architecture
• Component n
• Scale and performance
• Security
• High availability
• Testing

Architecture:

A high-level diagram of the system's architecture, including the main components and their interactions, and a detailed description of the Kubernetes resources that will be used (e.g. Pods, Services, Deployments, etc.).

Component n

Given n components in the system, repeat the for every component. Consider creating a new page for complex components and placing it under this page as a subpage.
