See the magic behind Quarkus, the cloud-native Java framework

See the magic behind Quarkus, the cloud-native Java framework

Our first DevNation Live regional event was held in Bengaluru, India in July. This free technology event focused on open source innovations, with sessions presented by elite Red Hat technologists.

Quarkus is revolutionizing the way that we develop Java applications for the cloud-native era, and this tutorial, presented by Edson Yanaga, explains why. Yanaga looks at how Quarkus works and the techniques it uses to achieve its dramatic startup speed improvements. He also covers the Quarkus extension API, so you can see how to write your own extensions.

Future-proof monolithic applications with modular design

Future-proof monolithic applications with modular design

DevNation tech talks are hosted by the Red Hat technologists who create our products. These sessions include real solutions and code and sample projects to help you get started. In this talk, you’ll learn about future-proofing applications from Eric Murphy and Ales Nosek, Architects with Red Hat Consulting.

When building an MVP software application, you may immediately jump to a microservices architecture because it’s the new norm for building cloud-native applications. You may also be skeptical about starting off with a monolith because of the perception of such applications as relics of the past.

In this talk, we will show how to evolve a monolithic application in a highly controlled way using modular design principles. We will also demonstrate a future-proofed Quarkus + Vert.x application that is both a monolith and microservices while using the same code and modular design.

Building freely distributed containers with Podman and Red Hat UBI

Building freely distributed containers with Podman and Red Hat UBI

DevNation tech talks are hosted by the Red Hat technologists who create our products. These sessions include real solutions and code and sample projects to help you get started. In this talk, you’ll learn about building containers with Podman and Red Hat Universal Base Image (UBI) from Scott McCarty and Burr Sutter.

We will cover how to build and run containers based on UBI using just your regular user account—no daemon, no root, no fuss. Finally, we will order the de-resolution of all of our containers with a really cool command. After this talk, you will have new tools at the ready to help you find, run, build, and share container images.

Testing in production: From DevTestOops to DevTestOps

Testing in production: From DevTestOops to DevTestOps

DevNation tech talks are hosted by the Red Hat technologists who create our products. These sessions include real solutions and code and sample projects to help you get started. In this talk, you’ll learn about testing in production from Alex Soto, Red Hat Software Engineer.

DevOps has grown in popularity in recent years, particularly in software companies that want to reduce lead time to be measured in days/weeks instead of months/years. To make sure your software does the right things and does those things right, you need to test it implacably. Many companies, however, see the testing phase as a bottleneck that slows product release. To change that, we need a new approach — making the release process of an application a testing process and involving QA from the beginning.

In this presentation, we will actively demonstrate several techniques that you can use immediately to start testing in production and speeding up your release cycle.

Cloud-native integration with Kubernetes and Camel K

Cloud-native integration with Kubernetes and Camel K

Our first DevNation Live regional event was held in Bengaluru, India in July. This free technology event focused on open source innovations, with sessions presented by elite Red Hat technologists.

In this session, Kamesh Sampath shows how to apply common Enterprise Integration Patterns (EIP) with Apache Camel, Kubernetes, and Red Hat OpenShift. You will see how the new Camel K framework helps in deploying Camel DSL code as “integrations” in Kubernetes/OpenShift.
