Editor's Notes
- Welcome to the monoliths to microservices app transformation hands-on workshop. This workshop delivers a full day of training, including details about Red Hat’s philosophy to modern application transformation and a set of hands-on learning modules for participants to complete throughout the day.
- Participants will use a browser-based environment, so no heavy requirements on the hardware side - all that’s needed is a modern browser, and even iPads or Android tablets will work, though your mileage may vary. As the lab material is rather technical, participants should be a Java developer or architect, or at least have a development background. Familiarity with linux container technology is good to have, though not required.
- Participants will learn about how application modernization plays a key role in the new digital transformation era, and how Red Hat technologies and approach can bring real business value to organizations looking to modernize. The workshop teaches fundamentals of migrating and modernizing existing applications from legacy platforms like Weblogic to modern and flexible platforms like Red Hat JBoss Enterprise Application Platform. Participants will use the Red Hat Application Migration Toolkit to provide detailed analysis of an example application, perform the migration, and then complete the journey to cloud and containers using Red Hat OpenShift. Next, a developer-centric module on OpenShift developer fundamentals shows participants how to streamline application development in the cloud using DevOps principles, containers, and OpenShift, including the use of OpenShift pipelines to automate promotion of applications across different environments, from the developer’s desktop to production. Microservices are then introduced, and participants will build them using a variety of different microservice runtimes offered through Red Hat OpenShift Application Runtimes, including Spring Boot, WildFly Swarm, Eclipse Vert.x, and Node.js. The workshop also discuss the benefits and challenges of microservices, including how reactive systems and reactive programming can solve thorny issues around performance, and how service mesh concepts can reduce the burden on developers while at the same time providing rich features for operators of microservice applications. Finally, the workshop closes with a discussion on microservice packaging techniques, such as Uber JARs and their application in a containerized world, and how API-led modernization featuring Red Hat 3Scale provides new business aveues with customers and partners.
- A typical agenda for the day looks like this. In the morning, after introductions, a short discussion on how migration and modernization can breathe new life into existing apps. Participants will then spend time completing the lab, followed by a short wrap-up for the first module. Each module is presented roughly in the same style, with a short introduction followed by participants getting hands-on with Red Hat, and a short wrap-up to reinforce what they just learned.
- Participants will use a browser-based environment, so no heavy requirements on the hardware side - all that’s needed is a modern browser, and even iPads or Android tablets will work, though your mileage may vary. As the lab material is rather technical, participants should be a Java developer or architect, or at least have a development background. Familiarity with linux container technology is good to have, though not required.
- The hands-on portion of the workshop uses a browser-based environment called Katacoda. Each of the modules in the workshop is supported by one or more Scenarios, which are completed in the order on the agenda.
