What needs to be implemented in the application for it to be considered a microservices architecture?

For an application to be considered built on a microservices architecture, the following key principles must be implemented:

• Decomposition into independent services — each microservice is responsible for a specific business function and can be developed and deployed separately.

• Data isolation — each service manages its own database or storage.

• Interaction via API — services communicate with each other through well-defined interfaces (usually REST, gRPC, or messaging).

• Autonomy and independent deployment — updating one service does not require stopping the entire system.

• Orchestration and service management — using tools to manage the lifecycle of microservices (e.g., Kubernetes).

• Monitoring and logging — centralized collection of metrics and logs to track the state and performance.

Implementing these aspects allows the application to conform to a microservices architecture.
