What is a Architecture Diagram?
An architecture diagram provides a visual representation of a system's technical infrastructure, showing services, groups, and their connections. It uses icons and grouping to clearly communicate how components like servers, databases, storage, and cloud services relate to each other. Architecture diagrams are essential for documenting infrastructure and communicating system design.
Common Use Cases
- •Cloud architecture - Document AWS, GCP, or Azure infrastructure
- •Microservice design - Visualize service dependencies and communication
- •Infrastructure documentation - Map servers, databases, and networks
- •System design interviews - Communicate architecture decisions clearly
- •DevOps planning - Plan deployment architecture and service topology
