• Easy to develop and maintain by a small team without depending on other teams
• Independently installable as a separate entity, preferably in a container
• Offers easy-to-consume interfaces using synchronous protocols such as REST APIs, or asynchronous protocols such as Kafka or RabbitMQ

The keywords in terms of software being called a microservice are independently deployable, loosely coupled, and easily maintainable. Each microservice can have its own database servers to avoid sharing resources with other microservices. This will ensure the elimination of dependencies between the microservices.

The microservices architecture style is a software development paradigm for developing applications using purely microservices. This architecture even includes...
