![]() ![]() Building Scalable Applications and Microservices: Adding Messaging to Your Toolboxįor a summary of the semantics of queues and topics:.Implementing enterprise integration patterns with AWS messaging services: publish-subscribe channels.Implementing enterprise integration patterns with AWS messaging services: point-to-point channels.If loose-coupling is important, especially in a system that requires high resilience and has unpredictable scale, another option is asynchronous messaging.Īsynchronous messaging is a fundamental approach for integrating independent systems, or building up a set of loosely coupled systems that can operate, scale, and evolve independently and flexibly. As our colleague Tim Bray said, “ If your application is cloud-native, or large-scale, or distributed, and doesn’t include a messaging component, that’s probably a bug.” In this blog post, we will outline some fundamental benefits of asynchronous messaging for the communications between microservices.įor a refresher on the fundamental messaging patterns and their implementations with Amazon SQS, Amazon SNS, and Amazon MQ, please read our previous blog posts After all, this is why there are mitigation patterns like circuit-breaker in the first place. REST APIs can also add some heavy lifting to your infrastructure that we will discuss further below. While REST APIs are common and useful in microservices design, REST APIs tend to be designed with synchronous communications, where a response is required. A request coming from an end-user client can trigger a complex communications path within your services landscape, which can effectively add coupling between the services at runtime. After all, your microservices landscape is a distributed system. To achieve the promises of microservices, such as being able to individually scale, operate, and evolve each service, this communication must happen in a loosely coupled and reliable manner.Ī common way to loosely couple services is to expose an API following the REST architectural style. REST APIs are based on the architecture of the web and provide loose coupling between communicating parties. REST APIs offer a great way to decouple interfaces from concrete implementations, and to advise clients about what they can do next, by the use of links and link relations. One of the implications of applying the microservices architectural style is that much communication between components happens over the network. This post is courtesy of Dirk Fröhner, Sr.
