Spring Boot

Spring Boot is rapidly becoming the most popular of the Java frameworks for building cloud-native microservices. Here are a few good reasons:

• It has a foundation on Spring and Spring MVC, which is already popular in enterprises
• Like Dropwizard, it assembles the most reasonable defaults and takes an opinionated approach to assembling the required dependencies for the services, reducing the XML required for configuration
• It integrates Spring Cloud out of the box, which provides useful libraries such as Hystrix and Ribbon, for distributed service development that is required for cloud deployment
• It has a lower learning curve; you can get started in minutes (as we shall see next)
• It has the concept of 40+ starter Maven Project Object Models (POMs) that give good flexibility for choosing and developing applications

Spring Boot is suitable for a wide spectrum of the workloads that are suitable for cloud-native deployments and hence is a good first choice for most use cases.
