Node.js for Red Hat OpenShift Application Runtimes wins a Devie award

Node.js for Red Hat OpenShift Application Runtimes wins a Devie award

For the past year and a half or so, Red Hat Middleware has provided a supported Node.js runtime on OpenShift as part of Red Hat OpenShift Application Runtimes (RHOAR). Our goal has been to provide rapid releases within a week or two of the upstream Node.js core project, booster applications to get developers up and running quickly, and, of course, provide world-class service and support for customers.

This past week at the DeveloperWeek 2019 conference in San Francisco, that focus and dedication paid off as Red Hat was awarded a “Devie” award in the category of “Code Frameworks and Libraries.” I couldn’t have been more thrilled to accept the award on behalf of our team.

Extending support to Spring Boot 2.x for Red Hat OpenShift Application Runtimes

Extending support to Spring Boot 2.x for Red Hat OpenShift Application Runtimes

What Red Hat is providing

Red Hat OpenShift Application Runtimes (RHOAR) is a recommended set of products, tools, and components for developing and maintaining cloud-native applications on the Red Hat OpenShift platform. As part of this offering, Red Hat is extending its support to Spring Boot 2 and related frameworks for building modern, production-grade, Java-based cloud-native applications.

Spring Boot lets you create opinionated Spring-based standalone applications. The Spring Boot runtime also integrates with the OpenShift platform, allowing your services to externalize their configuration, implement health checks, provide resiliency and failover, and much more. To learn more about how Spring Boot applications integrate with the wider Red Hat portfolio, check out the following OpenShift Commons Briefing by Thomas Qvarnstrom:

Monitoring Node.js Applications on OpenShift with Prometheus

Monitoring Node.js Applications on OpenShift with Prometheus

Observability is Key

One of the great things about Node.js is how well it performs in a container. Its fast start up time, and relatively small size make it a favorite for microservice applications on OpenShift. But with this shift to containerized deployments comes some complexity. As a result, monitoring Node.js applications can be difficult. At times it seems as though the performance and behavior of our applications become opaque to us. So what can we do to find and address issues in our services before they become a problem? We need to enhance observability by monitoring the state of our services.

Instrumentation

Instrumentation of our applications is one way to increase observability. Therefore, in this article, I will demonstrate the instrumentation of a Node.js application using Prometheus.

Announcing: Thorntail 2.2 General Availability

Announcing: Thorntail 2.2 General Availability

An Introduction to Thorntail

Today Red Hat is making Thorntail 2.2 generally available to Red Hat customers through a subscription to Red Hat OpenShift Application Runtimes (RHOAR). RHOAR provides application developers with a variety of application runtimes running on the OpenShift Container Platform.

Thorntail is the new name for WildFly Swarm, and bundles everything you need to develop and run Thorntail and MicroProfile applications by packaging server runtime libraries with your application code and running it with java -jar. It speeds up the transition from monoliths to microservices and takes advantage of your existing industry standard Java EE technology experience.

Building Container-Native Node.js Applications with Red Hat OpenShift Application Runtimes and Istio

Building Container-Native Node.js Applications with Red Hat OpenShift Application Runtimes and Istio

For developers working on a Kubernetes-based application environment such as Red Hat OpenShift, there are a number things that need to be considered to fully take advantage of the significant benefits provided by these technologies, including:

  • How do I communicate with the orchestration layer to indicate the application is operating correctly and is available to receive traffic?
  • What happens if the application detects a system fault, and how does the application relay this to the orchestration layer?
  • How can I accurately trace traffic flow between my applications in order to identify potential bottlenecks?
  • What tools can I use to easily deploy my updated application as part of my standard toolchain?
  • What happens if I introduce a network fault between my services, and how do I test this scenario?

These questions are central to building container-native solutions. At Red Hat, we define container-native as applications that conform to the following key tenets:

  • DevOps automation
  • Single concern principle
  • Service discovery
  • High observability
  • Lifecycle conformance
  • Runtime confinement
  • Process disposability
  • Image immutability

This may seem like a lot of overhead on top of the core application logic. Red Hat OpenShift Application Runtimes (RHOAR) and Istio provide developers with tools to adhere to these principles with minimal overhead in terms of coding and implementation.

In this blog post, we’re specifically focusing on how RHOAR and Istio combine to provide tools for DevOps automation, lifecycle conformance, high observability, and runtime confinement.

How to Debug Your Node.js Application on OpenShift with Chrome DevTools

How to Debug Your Node.js Application on OpenShift with Chrome DevTools

Recently, I wrote a post called Zero to Express on OpenShift in Three Commands, which shows how to get started using Node.js, Express, and OpenShift together as fast as possible using the Node.js s2i (source-to-image) images that were recently released as part of Red Hat OpenShift Application Runtimes (RHOAR).

This post will add to the last one and show how we can start to debug and inspect our running code using the Chrome Developer Tools (DevTools) inspector.

Getting Started with Istio and Jaeger on Your Laptop

Getting Started with Istio and Jaeger on Your Laptop

[Cross posted from the OpenShift blog]

About a year ago Red Hat announced its participation as a launch partner of the Istio project, a service mesh technology that creates an application focused network that transparently protects the applications from abnormalities in environments. The main goals of Istio are enhancing overall application security and availability through many different capabilities such as intelligent routing, circuit breaking, mutual TLS, rating, and limiting among others. Ultimately Istio is about helping organizations develop and deploy resilient, secure applications and services using advanced design and deployment patterns that are baked into the platform.

As part of our investments in making the technology easily consumable to Kubernetes and OpenShift users, Red Hat has created a ton of content:

  • learn.openshift.com: A web-based OpenShift and Kubernetes learning environment where users get to interact through the web browser with a real running instance of OpenShift and Istio service mesh with zero install time and no sign-up required.
  • Istio tutorial: Want to try the web-based scenario yourself from scratch? This Git repo contains instructions on how to set up an environment for yourself.
  • Introducing Istio Service Mesh for Microservices book by Christian Posta and Burr Sutter
  • Blog posts on the OpenShift and Red Hat Developer blogs

Next DevNation Live: Enterprise Node.js on OpenShift, April 19th, 12 p.m. EDT

Next DevNation Live: Enterprise Node.js on OpenShift, April 19th, 12 p.m. EDT

The next online DevNation Live Tech Talk is Thursday, April 19th at 12pm EDT. The topic is “Enterprise Node.js on Red Hat OpenShift” presented by Lance Ball, and hosted by Burr Sutter. The popularity of JavaScript on the front end and the JSON format for data has led to a “JavaScript Everywhere” movement with Node.js at the center. Node.js offers developers an event-driven, non-blocking I/O model that is perfect for high concurrency, low-latency applications that run across distributed devices. Its reactive architecture makes it an ideal technology for containerized microservices architectures you’ve been hearing so much about.

What does this mean for your enterprise? Where does it fit, and how can Red Hat OpenShift Application Runtimes help you use this technology?

Join this session for the answers. We’ll also demonstrate how quickly you can set up non-trivial enterprise-grade Node.js applications on Red Hat OpenShift Container Platform. We’ll explore how to integrate with other open source technologies, such as Istio, and discuss strategies for your Node.js development and deployment pipeline, including canary and blue/green deployment strategies.

Register now and join the live presentation at 12 p.m. EDT, Thursday, April 19th.
