The Ballerina programming language implements the bulk of its cloud-native functionality by integrating with the cloud-native ecosystem. This consists of deployment, communication, observability, security, and many more. Ballerina acts as the missing piece in combining these technologies together to complete the cloud-native development experience.

What type of code examples do you want to see. Are you happy with fragments from Q&A web sites? Do you prefer blog posts that provide extensive text to support the examples. Do you want short simple examples or full blown applications. I know what I want and thats is what I want to present. But it is more than just how much code there is in an example but how it is documented, how it adheres to best practices and conventions and how realistic it is.

There are hundreds of programming languages and just as many programming styles. How can an agile organisation serve such myriad needs of library consumers without excluding relevant language paradigms? Should we write and maintain libraries written natively in multiple languages, like Python, C, Go, Java, Node.js and Rust?

For Eclipse projects the CI/CD infrastructure is provided by Eclipse Foundation. With more and more new projects coming up Foundation needs to optimize its existing infrastructure.
One way to solve this problem is to have private cloud deployed on the hardware, run the tasks in their own containers using cutom docker images. Foundation deployed Openshift as its private cloud platform and created Jenkins instances to use Openshift based containers. This resulted in migration of exiting CI/CD infrastructure to newer Openshift based Jenkins instances.

Kubernetes enables possibilities to develop cloud native microservices or decompose traditional applications making them more technologically advanced with the help of containers. Currently, most of the Kubernetes solutions are offered on top of VMs and there is a room for further improvements. Implementing nested architecture of application containers running inside system containers opens additional flexibility of resource allocation and management, accelerates provisioning of the clusters and pods, as well as cuts the overall costs.

Are you interested in creating robotic applications in a more efficient way, focusing on what needs to be done instead of the how, and taking safety constraints into account?
Papyrus for Robotics is an open-source Eclipse-based modeling environment that supports code generation and reverse engineering for ROS2.
In this talk, we will develop a ROS2 application for a pick-and-place application with a robotic arm. The application model includes

In the last few years, the "Robocar" community of enthusiasts that build autonomous scaled vehicles (mostly 1:10) has grown significantly and the level of functionality that is achieved is amazing. Many of these projects use ROS/Python and start with available open source platforms. At itemis, we decided to build our vehicle based on other technologies that we see in production at our customers, such as C++ and Eclipse hosted communication frameworks.

A couple of years ago, continuous integration in the JVM ecosystem meant Jenkins. Since that time, a lot of other tools have been made available. But new tools don’t mean new features, just new ways. Beside that, what about continuous deployment? There’s no tool that allows to deploy new versions of a JVM-based application without downtime. The only way to achieve zero downtime is to have multiple nodes deployed on a platform, and let that platform achieve that e.g. Kubernetes.

When one’s app is challenged with poor performances, it’s easy to set up a cache in front of one’s SQL database. It doesn’t fix the root cause (e.g. bad schema design, bad SQL query, etc.) but it gets the job done. If the app is the only component that writes to the underlying database, it’s a no-brainer to update the cache accordingly, so the cache is always up-to-date with the data in the database.

Software developers create software. That’s somewhat natural. But what most software developers don't think about, is how this software is run in the end.
We (SSI Schaefer) have been facing challenges with deployment for years. SSI Schaefer is building large scale business applications based on the Eclipse RCP platform. These applications are installed on thousands of customer servers, and the client applications on even more customer client PCs. We absolutely need an easy, straight forward way to be able to package, transfer, install, configure, run and update these applications.
