Chris Richardson is a developer and architect. He is a Java Champion, a JavaOne rock star and the author of POJOs in Action, which describes how to build enterprise Java applications with frameworks such as Spring and Hibernate. Chris was also the founder of the original CloudFoundry.com, an early Java PaaS for Amazon EC2.
Today, he is a recognized thought leader in microservices and speaks regularly at international conferences. Chris is the creator of Microservices.io, a pattern language for microservices, and is writing the book Microservice Patterns, which is available as a Manning MEAP. He provides microservices consulting and training to organizations that are adopting the microservice architecture and is working on his third startup Eventuate, an application platform for developing transactional microservices.
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.
The microservice architecture functionally decomposes an application into a set of services. Each service has its own private database that’s only accessible indirectly through the services API. Consequently, implementing queries and transactions that span multiple services is challenging. In this presentation, you will learn how to solve these distributed data management challenges using asynchronous messaging. I describe how to implement transactions using sagas, which are sequences of local transactions, coordinated using messages. You will learn how to implement queries using Command Query Responsibility Segregation (CQRS), which uses events to maintain replicas. I describe the key role that messaging plays a microservice architecture.
We have all heard for a while that microservices are the solution to all of our problems. Now serverless is emerging as an even smaller component of the new way of building applications piece by piece. In our zeal to adopt the latest in architectural approaches, have we given sufficient thought to where they are going or what comes next?
If you are considering building an application with a microservice or serverless based architecture, come to this panel of experienced cloud developers and architects and learn what these technologies can do for you now, and what they will do in the future. Ask our panel questions on what works, what doesn't, and how to prepare today for the technology that's coming next.
