Chris Richardson 早年著有POJO in action一书，一个差不多60岁的老外老头，在此书中写下了40+的微服务模式，涵盖了设计、开发、部署、测试微服务的方方面面。
引用Chris Richardson一书中描述：
The microservice architecture isn’t a silver bullet—there are significant drawbacks, including complexity.
微服务不是银弹，有着重要的缺陷，包括复杂性。
优点：
It enables the continuous delivery and deployment of large, complex applications. Services are small and easily maintained. Services are independently deployable. Services are independently scalable. The microservice architecture enables teams to be autonomous. It allows easy experimenting and adoption of new technologies. It has better fault isolation.
缺点：
Finding the right set of services is challenging. Distributed systems are complex, which makes development, testing, and deployment difficult. Deploying features that span multiple services requires careful coordination. Deciding when to adopt the microservice architecture is difficult.
