Explore Microservices Architecture as an editable mindmap. Follow color-coded branches for Clients & gateway, Independent services, Messaging, Owned data, Observability, with supporting ideas and curved connections.
A mindmap of Microservices Architecture, with the main ideas arranged around a central topic and connections that show how they relate.
Microservices Architecture: an editable mindmap
The interactive MindMap canvas for this explanation — every lane, row and arrow above is a real QueryChart diagram you can open and edit.
How to read this mindmap
- Begin at “Microservices Architecture” in the centre, then explore any branch that answers your question. The branch colors keep each group of ideas together.
- Curved lines show relationships; arrowheads appear only where one idea leads to another. Select any idea in the editor to change its text, position, or connections.
Clients & gateway
This branch brings together “Web and mobile clients”, “The gateway is the single entry point: it routes each request to the right service, handles authentication and often aggregates responses from several services.”.
Independent services
This branch brings together “Orders service”, “Payments service”, “Teams deploy and scale services independently”, “Users service”.
Messaging
This branch brings together “Services communicate by publishing events rather than calling each other directly — so one service's change or outage never blocks another.”.
Owned data
This branch brings together “The defining rule of microservices: no shared schema. Each service's data is private to it, which is what allows teams to deploy independently.”.
Observability
This branch brings together “Metrics, logs and traces feed one view”.
Connections across the map
Each service is independently deployable: the property everything else in the architecture exists to protect.
Services communicate through the message bus and own their own databases; shared state is the anti-pattern.
The API gateway is the system's single front door; clients never talk to services directly.
Independence must be paid for with observability: many services are only manageable when one view covers them all.
Microservices orchestrate the containers Docker packages: the two visuals connect.

When to use this visual
- Teaching a team why microservices exist and what the trade-offs actually are before they adopt them.
- Documenting an existing system's service boundaries, message topics and data ownership for onboarding.
- Auditing for the anti-patterns: a shared database or a service calling another service directly is a boundary leak.

Frequently asked questions
What is microservices architecture?
It is an architectural style in which an application is built from many small services, each responsible for one business capability, deployed independently and owning its own data. Services communicate over a network (typically HTTP and a message bus) rather than sharing memory or a database. The benefits are independent deployability and team autonomy; the costs are network complexity and the need for observability.
Why does each microservice own its own database?
Because shared data is the coupling that breaks independent deployment. If two services read and write the same table, they cannot change their schema, scale or deploy without coordinating. Owning its own data store is what lets a service evolve and scale on its own schedule: the rule the "Each service owns its own database" band in the visual enforces.
What is the role of the API gateway in microservices?
The gateway is the system's single entry point. It routes requests to the right service, handles cross-cutting concerns like authentication and rate limiting, and can aggregate responses from several services into one. Clients talk to the gateway, never directly to individual services, which keeps the service topology free to change behind it.
When should you NOT use microservices?
When the system is small or the team is small. Microservices trade architectural complexity (network failures, distributed transactions, observability) for independent deployability, and that trade only pays off once a team is large enough that independent deployability is the binding constraint. Many teams' problems are solved by a well-modularised monolith, which is the subject of the monolithic architecture visual.
