Java EE

Domain-Driven Design (DDD) is an architectural approach that strongly focuses on materializing the business domain in enterprise software through disciplined object-oriented analysis. This session demonstrates first-hand how DDD can be elegantly implemented using Jakarta EE via an open source project named Cargo Tracker.

Cargo Tracker maps DDD concepts like entities, value objects, aggregates and repositories to Jakarta EE code examples in a realistic application. We will also see how DDD concepts like the bounded context are invaluable to designing pragmatic microservices.

Why Jakarta EE Developers are First-Class Citizens on Azure

Reza Rahman (Microsoft Corp.)

Java EE/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 Java EE/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 is changing now and going forward.

Jakarta EE on Azure Magic Mystery Show

Reza Rahman (Microsoft Corp.)

This fast-paced, demo-driven, entirely slide free session will show you the many ways of effectively deploying a Jakarta EE application to Azure. We will start by deploying a local Jakarta EE application to basic IaaS on Azure. We will then deploy the same application to a managed Azure PaaS. Finally we will deploy the application to Azure using Docker and Kubernetes. We will discuss the trade-offs of each approach on the way, offering guidelines for which approach might be best for your application on the cloud.

Jakarta NoSQL Powered by Cosmos DB on the Cloud

Reza Rahman (Microsoft Corp.)

Jakarta NoSQL is a new standard for accessing non-relational databases on the cloud. Cosmos DB is a best-of-breed planet scale database service on Azure that is compatible with MongoDB, Cassandra, Gremlin and more.

In this session we will see how to use these technologies together in cloud native Jakarta EE applications. Most of the session will be demos with a minimal number of slides.

Java EE inside Application Containers, System Containers and VMs. Difference and Use Cases

Ruslan Synytsky (Jelastic)

The benefits of virtualization and cloud technologies already became clear with all published articles and million of speeches. However, more available options produce the "problem of choice". There is a question which periodically comes up - what virtualization technology to choose for a specific use case. In this session, we'll analyze the difference of running Java EE projects inside application containers, system containers and VMs.

Leading financial legacy systems into the future with Jakarta EE

Ville Misaki (Rakuten, Inc.)

The technology landscape is changing at an ever-accelerating speed, and established financial institutions are facing stiff competition from FinTech startups. Rigid architectures, based around risk-avoidance, become a blocker to innovation, where small agile operations can try new things without remorse. Users have gotten accustomed to always-available, instant services, where processing in daily or monthly batches just don't cut it anymore.

HTTP/2 and What it Means for the Jakarta EE Ecosystem

Reza Rahman (Microsoft Corp.)

HTTP is very easily the most important standard in server-side Java. The much awaited HTTP/2 standard is now complete, was fifteen years in the making and promises to radically speed up the entire web through a series of fundamental protocol optimizations.

In this session we will take a detailed look at the changes in HTTP/2 and discuss how it may change the Jakarta EE ecosystem including the foundational Jakarta Servlet 4 specification included in Jakarta EE 8.
