Successful applications have a habit of growing. What’s more, the rate of growth increases over time because the development team typically gets larger. Eventually, the application will become extremely large and the organization ends up in monolithic hell. All aspects of development, testing and deployment are slow and painful. It’s impossible for the developers to keep up with the demands of the business. And, to make matters worse the application uses a technology stack that is increasingly obsolete. The way to escape monolithic hell is to migrate to the microservice architecture. In this talk, you will learn about the essential characteristics of microservices. I describe the benefits and drawbacks of the microservice architecture and when it makes sense to use it. You will learn about the design problems you will encounter when using microservices. I describe how to solve this problems by applying the microservices pattern language. You will learn how the microservice architecture accelerates the delivery of large, complex applications.
