Jakarta EE 9 and Beyond

Jakarta EE 9 lowers the barriers of entry, eases migration, and lays a foundation for future innovation. Jakarta EE 9.1 takes this even further by offering Java SE 11 support.

In this session, I will go through what Jakarta EE 9.1 brings to the table and how this release lowers the barriers of entry, eases migration, and lays the foundation for a platform for future innovation. We will also look ahead to what future releases may bring.

The session includes a demo including converting from the javax. to jakarta. namespace as well as looking at available implementations.

LEMMA: Eclipse-Powered Modeling of Microservice Architecture

Florian Rademacher (IDiAL Institute, University of Applied Sciences and Arts Dortmund)

Microservice Architecture (MSA) is one of the recent trends in the area of Software Architecture. MSA promotes to decompose software systems into distributed services, each focusing on a well-defined, distinct task with the greatest possible independence in both technical and organizational hindsight.

MicroProfile GraphQL and JPA: Meant for each other

Andy McCright (IBM)

Adam Anderson (IBM)

Can it really be that easy?! Yes it can! Come check out this session where we'll discuss and demo how you can rapidly build data-driven microservices using GraphQL. MicroProfile GraphQL makes it simple to create Java-based GraphQL services with a few annotations. JPA makes it simple to access data in a database. When you put these two technologies together, sparks will fly (the good kind)! With very little code, we can build services that allow clients to get exactly what they want from the database.

Modularity is more evolved than invented

Todor Boev (Software AG)

In this talk we will follow a single rule to gradually discover the design principles at the root of most modular runtimes: OSGi, java modules, even microservices. We will contend that the degree to which a software system is committed to following this rule drives it's final shape in a way similar to natural evolution. We believe this will help software professionals understand why their modular applications exhibit certain traits like the particular distribution of complexity between modules.

Secure Microservices made easy with Eclipse MicroProfile JWT

Emily Jiang (IBM)

Are you wondering how to secure microservices? Eclipse MicroProfile JWT (https://microprofile.io/) is the answer. MicroProfile JWT designs a token based authentication and authorization mechanism, which enables authorized access from clients to services or from services to services by using JWT token.

From Monolith to Microservices using OSGi

Patrick Paulin (Modular Mind)

Microservices are often created by refactoring a service out of an existing monolithic application. There are some who suggest that for greenfield development it is actually preferable to build a monolith first and allow microservices to be pulled out as service boundaries are discovered. But whether you’re dealing with an existing Java-based monolith or are looking for ways to develop new functionality, the OSGi framework and Eclipse OSGi tooling can do a lot to improve your development process.

Microservices and the Modular UI

Patrick Paulin (Modular Mind)

While microservice architecture has become extremely common, its use in the UI layer is still somewhat rare and difficult. Building microservices in the UI layer (sometimes called Micro Frontends) requires well-thought-out support frameworks that allow for collaboration between loosely coupled and independently deployable components. Well it turns out that the Eclipse Platform developers have been innovating and fine-tuning such frameworks for the last 20 years, and in this session we'll explore what they have to teach us.

3 easy performance improvements in your microservices architecture

Nicolas Fränkel (Hazelcast)

While a microservices architecture is more scalable than a monolith, it has a direct hit on performance.

To cope with that, one performance improvement is to set up a cache. It can be configured for database access, for REST calls or just to store session state across a cluster of server nodes. In this demo-based talk, I’ll show how Hazelcast In-Memory Data Grid can help you in each one of those areas and how to configure it. Hint: it’s much easier than one would expect.

End-to-End Microservices - with Eclipse MicroProfile

Ivar Grimstad (Eclipse Foundation)

Eclipse MicroProfile provides a set of APIs for creating cloud-native microservices. In this session, I will start with a blank sheet and build a set of well documented, configurable microservices that communicates with each other in a secure, traceable and fault-tolerant way using implementations from a wide range of vendors.

You will get an overview of the technologies and learn how to get started with Eclipse MicroProfile to create portable 12-factor microservices in an efficient manner.
