Introduction to Microservices with Java Spring Boot

series: "Microservices with Spring Boot" --- part: 1 --- chapter: "1" --- description: "A practical introduction to microservices architecture using Java Spring Boot — what they are, when to use them, and how to build your first service." --- # MicroServices using Java Spring Boot ## What are Microservices? Microservices are a software development approach that structures an application as a collection of loosely coupled services. Each service is self-contained and performs a single function. Microservices are typically developed and deployed independently, and they communicate with each other through APIs. ## Benefits of Microservices Microservices offer several benefits over traditional monolithic applications, including: * **Scalability:** Microservices can be scaled independently, which makes it easier to scale the overall application. For example, if the product catalog microservice is experiencing high traffic, it can be scaled up without affecting the other microservices. * **Resilience:** If one microservice fails, the other microservices can continue to operate, which makes the overall application more resilient. For example, if the payment processing microservice fails, orders can still be taken and stored, and the payment can be processed later when the microservice is back up. * **Agility:** Microservices can be developed and deployed independently, which makes it easier to iterate on the application and make changes. For example, a new feature can be implem
