To facilitate communication between microservices, a common architectural pattern is to use a ___ Bus. This bus acts as a central messaging system through which microservices can send and receive messages. By decoupling the sender and receiver, this pattern enables asynchronous communication and helps maintain loose coupling between microservices. The use of a message bus also allows for the implementation of features like event-driven architecture and publish/subscribe messaging.
The Message Bus provides the following benefits:
Reliability: The message bus ensures the reliable delivery of messages between microservices, even in the event of failures or temporary unavailability of individual microservices.
Scalability: The use of a message bus enables the horizontal scaling of microservices. New instances of microservices can be added to handle increased message load without affecting the existing services.
Flexibility: The message bus can support different messaging patterns, such as point-to-point or publish/subscribe, allowing for flexible communication between microservices depending on the requirements.
Interoperability: The message bus facilitates communication between microservices developed in different programming languages or frameworks by providing a common messaging protocol.
