Join us to learn how to develop an agile evolutionary architecture which allows delaying unnecessary technical decisions until the time it’s safe to make them. MicroProfile features will get us started quickly. Start simple and easily refactor to improve the important parts later. Open source implementations of MicroProfile like Payara Micro add further flexibility; it can range from simple messaging to Apache Kafka or Amazon SQS for high performance messaging; from simple config files to distributed config. Come to learn how to think flexibly and adapt to the future.In a live demonstration, you’ll see how an example application can be evolved gradually to deliver business value quickly and how to add new features later. You’ll learn how to evolve the application according to changing requirements without creating a ball of mud in the future.
