Scale your microservices by MicroProfile Metrics on Kubernetes

One of the advantages of microservices is that you can easily scale your applications. Kubernetes, which is the de-facto standard Docker orchestration tool, provides some scaling methods. They are basically designed to use Pod/Cluster related metrics such as CPU and memory consumptions. But sometimes, they do not have enough information to scale your real applications.

On the other hand, MicroProfile Metrics can produce application specific metrics, such as thread pool or database connection usage, which are useful as the trigger to scale.

Innovating MicroProfile with Quarkus and SmallRye

Martin Štefanko (Red Hat, Inc.)

MicroProfile is already established as a standard way of building cloud-native applications in Java. Compared to the traditional JVM development speeds, it is already skyrocketing its way through the Java market, continuously delivering releases every few months. However, if we want to compete with the speeds of other non-JVM languages commonly utilized in cloud-native application development (for instance, Node or Go), we need to go even faster. This is where Quarkus steps in. With its really frequent releases, it boosts user applications with new features every few weeks.

Faster Data Access with MicroStream

Rudy De Busscher (Payara Services Limited)

Microservices are used more and more but many of them need to access data. Using a database is well established but also slow as data need to be retrieved from an external system in another format and structure and thus requires a mapping.

Explore the new Jakarta Core Profile

Rudy De Busscher (Payara Services Limited)

The Jakarta EE 10 release contains the new Core profile which is targeted to smaller runtimes, especially for microservices.

This talk will explore the reasoning behind the profile, its contents, and what might be missing in the profile to be used successfully in production, etc ...

We will also explore the products that already support the core profile and show a little demo of how you can use them.

Eclipse JKube the Drone to your Cloud Native Java CI/CD

Kamesh Sampath (Harness)

Over the past few years, Kubernetes has matured enough to be the favorite application orchestration platform i.e. Cloud Native (Java) Application platform, but it still missed one crucial feature of in-cluster build and deploy of the applications. The missing feature made the continuous integration and deployment(CI/CD) to be less effective on Kubernetes based platforms. The market had various solutions to solve the problem but 99% of the solutions missed something — being “Kubernetes Native” and naturally built for “K(C)loud Native Applications”.

MicroProfile: Current and Future

Emily Jiang (IBM)

MicroProfile 5.0 aligns with the latest Jakarta EE release, Jakarta EE 9.1. With this release, you will be able to use jakarta.* namespaces in your applications. Afterwards, MicroProfile 5.1 and 6.0 are in the planning phase. The main focus is Metrics, Telemetry Tracing and Jakarta EE 10 alignment. This session will bring you up to date with the latest release of MicroProfile with a live demo on Open Liberty. Finally, Emily will discuss the future direction of MicroProfile.

They tell you it’s impossible, but it isn't: Building K8s Operators using Java and JEE

Daniel Pfeifer (RedBridge)

The industry seems to believe that the platform for our containers (Kubernetes) is exclusively based on Go to build the automations that we need. That is not the case, Kubernetes operators, controllers and webhooks are REST and HTTP and looking at Jakarta EE we have had RESTful WebServices for so very many years so why not use the specification you’re already used to in order to to build the custom automations you need?

Microsoft Azure for Java Developers

David de Hoop (Team Rockstars IT)

You have this cool new Spring Boot Application on Azure? You mean AWS right!? Nobody runs Java on Azure? Well they do! I will take away all the prejudice and will show you that your Java app shouldn’t be married to AWS but can run just as swiftly in Azure! In this session I tell and show you how you can leverage the powers of Azure when you are running a microservice application based on Spring Boot and how to integrate the platform into your Eclipse IDE making sure a smooth development experience is archieved.
