Why Java/Jakarta EE Developers are First-Class Citizens on Azure

Java/Jakarta EE is an important technology to support on Azure. Enterprise Java is a heterogenous ecosystem with as much as a third of workloads still running on Jakarta EE application servers such as WebLogic, WebSphere/Open Liberty, JBoss EAP, WildFly, and Payara. This is particularly true for large enterprises that need to lift and shift their existing mission-critical, largely monolithic applications to Azure. Traditionally, Azure has not focused on strong support for such workloads but that has changed now, in a big way.

This session will outline the efforts to better support Jakarta EE workloads on Azure. We will touch on the history of the open-standard enterprise Java movement and why open standards are and remain important to enterprises. We will discuss what is possible now, what is coming soon and what is further afield. This includes services, tools and guidance to better support Jakarta EE users opting for virtual machines, Kubernetes, or PaaS. It also includes integration with Azure services such as the Azure Service Bus through Jakarta EE APIs such as JMS.

This is also an invaluable opportunity to hear from you and better understand how Microsoft can support you best.

2. Agenda • Java/Jakarta EE ecosystem context • Java/Jakarta EE on Azure current capabilities • Java/Jakarta EE on Azure roadmap
3. Ecosystem
4. The Importance of Jakarta EE • Java/Jakarta EE is an important part of Java ecosystem and cloud • 30-40% of new and existing Java applications run on Jakarta EE application servers • WebLogic, WebSphere/Liberty, JBoss EAP/WildFly • 70-80% of Java applications depend on at least one or more Jakarta EE APIs • Tomcat, Hibernate, ActiveMQ, Jetty, Jersey, CXF, Spring, Quarkus, MicroProfile • Many of these applications are moving to the cloud now and in the near future 2023 Jakarta EE Developer Survey: https://outreach.eclipse.foundation/jakarta-ee-developer-survey-2023
5. The Jakarta EE Transition JPE J2EE 1.2 Servlet, JSP, EJB, JMS J2EE 1.3 CMP, JCA J2EE 1.4 JAX-WS Java EE 5 EJB 3, JPA, JSF, JAXB, JAX-WS Java EE 7 WebSocket, JSON, Concurrency, Batch, pruning Java EE 8 HTTP/2, SSE, Security, pruning Java EE 6 Profiles, CDI, JAX-RS, Bean Validation Jakarta EE 8 Open-source governance Jakarta EE 9.x Namespace transition Jakarta EE 10 New features, updates Jakarta EE 11 New APIs, features, updates
6. An Evolving Ecosystem
7. Current State
8. Mapping the Pathways Virtual Machines Containers Managed Services
9. Virtual Machines • In addition to Windows, Azure has long supported Linux virtual machines essential for Jakarta EE customers • Azure Marketplace includes Jakarta EE focused virtual machine images and templates • More will be done to enhance the developer experience
