What Are Microservices? Lightweight Software Development Explained


Microservices architecture tears down large monolithic applications with massive complex internal architectures into smaller, independently scalable applications. Each microservice is small and less complex to develop, update, and deploy.

When you think about it, why should those functionalities need to be built into a single application in the first place? In theory, at least, you can imagine they live in separate application and data silos without major problems. For example, if the average auction received two bids, but only a quarter of all sales received feedback, the bidding service would be at least eight times as active as the feedback application at any time of day. If these were combined into a single application, you end up running—and updating—more code than you need more often. The bottom line: Separating different functionality groups into separate applications makes intuitive sense.
