What's in this template

6 connected components you can rename, recolor, and extend with AI.

AuthDatabaseCacheCI/CDCDN / EdgePayments

A microservices architecture diagram maps how a large application is split into small, independently deployable services that each own their data and communicate over the network. Core parts include an API gateway routing client traffic, business services such as Auth, Orders and Payments, a per-service database, a message broker for async events, and a service discovery or caching layer that ties everything together.

Backend engineers, platform teams and architects reach for this diagram during system design reviews, onboarding and migration planning. It is the clearest way to explain service boundaries, data ownership and inter-service communication when moving off a monolith or documenting an existing distributed system for new team members.

Great for

  • System design reviews
  • Engineering onboarding docs
  • Monolith-to-microservices migration
  • Architecture decision records
  • Technical interviews

How to customize this template

  1. Open it in the canvas with Use this template.
  2. Put the component every request passes through, such as the gateway, broker or load balancer, in the center node, since every other node connects to it.
  3. Write the protocol into the label, for example Orders Service (gRPC) or Billing Events (async), so readers can tell calls from events.
  4. Swap generic icons for real vendor logos with the icon search, so the diagram matches the stack your team actually runs.
  5. Mark what you do not operate, such as third-party APIs, the CDN or a managed database, by adding (external) or (managed) to its label.
  6. Export a PNG or SVG for docs and slides, or a GIF or MP4 to keep the animation.

Frequently asked questions

What is a microservices architecture diagram?+

It is a visual map of an application broken into small, independently deployable services that communicate over the network. It shows the API gateway, each service, its database and the messaging layer between them.

What are the main components of a microservices architecture?+

Typical components are an API gateway, multiple business services, a database per service, a message broker for async events, service discovery and a caching layer.

How is microservices different from a monolith?+

A monolith ships as one deployable unit with a shared database, while microservices split functionality into many services that deploy and scale independently and own their own data.

Why use an API gateway in microservices?+

The API gateway gives clients a single entry point and handles routing, authentication, rate limiting and aggregation so services stay decoupled from external callers.
