Spring Microservices Patterns: Aggregator, Chain, and Shared Resources
Introduction
Microservices have emerged as a dominant architectural style for building scalable, maintainable, and modular software systems. In the Java ecosystem, the Spring framework, with its Spring Cloud project, is a popular choice for building microservices. As developers embrace this architectural style, certain patterns become evident, patterns that address recurring challenges in building microservices-based systems.
In this post, we’ll delve into three pivotal microservices patterns used in the Spring ecosystem: Aggregator, Chain, and Shared Resources. Each pattern addresses specific challenges and ensures that microservices can work seamlessly in a distributed environment.
Aggregator Pattern
Introduction to the Aggregator Pattern
Microservices often provide granular functionalities. When a client requires data or operations from multiple services, making individual requests can be inefficient. The Aggregator Pattern addresses this challenge. Acting as an intermediary layer, the Aggregator collates necessary data from various microservices and returns a unified response to the client.
