Is the network blocking your journey to hybrid cloud?

Ian Lawson

Is networking blocking your ability to connect cloud, on premises, and edge applications together? Running applications in the cloud across multiple hyperscalers, on premises data centers, and out at the network edge is a challenge. It generally means using complex and sometimes proprietary technologies to create network architectures to accomplish these goals.

Watch | Node.js and JavaScript at the edge: The why, what, and how

Node.js and JavaScript have always been a great fit for Internet of Things (IoT) applications due to their asynchronous nature and easy integration with C/C++ through add-ons. They are also heavily used in cloud and web-based applications running on existing IT infrastructure.

Trade-offs, bad science, and polar bears: The world of Java optimization

This talk introduces the basic principles of optimization and pitfalls to avoid. We’ll dive into why the exact same techniques that make Quarkus rocket-fast were considered a terrible idea fifteen years ago; why fast benchmarks make for slow programs; why Project Loom may not be the speedup you’re hoping for; and why—even though it can be easy to get wrong—optimization really, really matters.

Quarkus & Testcontainers: Perfect synergy for cloud-native development

Applications today don't exist in a vacuum; they typically communicate with other services, such as databases, message brokers, cache servers, and more. These interconnectivity requirements make it hard to do local/inner-loop development and testing efficiently, often forcing developers to write lots of code and configuration that never gets to production. What if there was a better way?

What if you didn’t need to write any extra code or configuration, and things just worked out of the box, making your life simpler and easier?

This session will introduce Testcontainers and explore the synergy between Testcontainers and Quarkus, showcasing all the integration that has been done for you, the developer, so that you don’t need to worry about a thing.

Getting GitOps | DevNation Tech Talk

Harriet Lawrence

In 2022 we heard your GitOps questions at meetups and gatherings, big stages, and local panels and one question was often top of mind: how do I get started? The benefits of GitOps are calling your name, but getting started isn’t that straightforward. 

Red Hat is excited to kick off 2023 with a DevNation TechTalk, focused on GitOps to help you sift through your questions. At DevNation, you’ll hear from passionate GitOps practitioners about the pitfalls to avoid and hurdles to jump while kicking off or evolving your GitOps practices. This event is aimed at audiences that are new to GitOps or early in their practice development within a cloud-native environment.

Exploring the power of OpenTelemetry on Kubernetes | DevNation Tech Talk

Modern cloud-native applications are incredibly complex systems. Keeping the systems healthy and meeting SLAs for our customers is crucial for long-term success. In this session, we will dive into the three pillars of observability - metrics, logs, tracing - which form the foundation of successful troubleshooting in distributed systems. You'll learn the gotchas and pitfalls of rolling out the OpenTelemetry stack on Kubernetes to effectively collect all your signals without worrying about a vendor lock in. Additionally we will replace parts of the Prometheus stack to scrape metrics with OpenTelemetry collector and operator.
