Elytron: A New Security Framework in WildFly/JBoss EAP

By Siddhartha De April 20, 2018April 19, 2018

Elytron is a new security framework that ships with WildFly version 10 and Red Hat JBoss Enterprise Application Platform (EAP) 7.1. This project is a complete replacement of PicketBox and JAAS. Elytron is a single security framework that will be usable for securing management access to the server and for securing applications deployed in WildFly. You can still use the legacy security framework, which is PicketBox, but it is a deprecated module; hence, there is no guarantee that PicketBox will be included in future releases of WildFly. In this article, we will explore the components of Elytron and how to configure them in Wildfly.

The Elytron project covers the following:

SSL/TLS
Secure credential storage
Authentication
Authorization

In this article, we are going to explore using SSL/TLS in WildFly with Elytron.

An API Journey: From Idea to Deployment the Agile Way–Part II

By Laurent Broudoux April 19, 2018April 19, 2018

This is part II of a three-part series describing a proposed approach for an agile API lifecycle from ideation to production deployment. If you missed part 1 or need a refresher, please take some time to read part I.

This series is coauthored with Nicolas Massé, also a Red Hatter, and it is based on our own real-life experiences from our work with the Red Hat customers we’ve met.

In part I, we explored how ACME Inc. is taking an agile API journey for its new Beer Catalog API, and ACME completed the API ideation, contract design, and sampling stages. Let’s go now to mocking.

Expanding architectural choices to better arm Red Hat Enterprise Linux developers

By Yan Fisher April 19, 2018April 18, 2018

Red Hat Enterprise Linux continues to deliver the best possible experience for enterprise system administrators and developers, as well as provide a solid foundation for moving workloads into both public and private clouds. One of the ways to enable such ubiquity is Red Hat’s multi-architecture initiative, which focuses on bringing Red Hat’s software portfolio to different hardware architectures.

Last week, Red Hat Enterprise Linux 7.5 went live. It brought forward several improvements relevant to developers and system administrators such as advanced GUI system management via the Cockpit console, which should help new Linux administrators, developers, and Windows users to perform expert tasks without having to get into the command line.

This release also marks a new milestone for Red Hat Enterprise Linux: all supported architectures are now simultaneously enabled. The list of supported architectures includes x86_64, PowerPC Big Endian and Little Endian, s390x, and the more recently introduced 64-bit Arm and IBM POWER9 architectures.

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

By Burr Sutter April 18, 2018April 17, 2018

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.

When Vert.x Meets Reactive eXtensions (Part 5 of Introduction to Vert.x)

By Clement Escoffier April 18, 2018April 17, 2018

This post is the fifth post of my Introduction to Eclipse Vert.x series. In the last post, we saw how Vert.x can interact with a database. To tame the asynchronous nature of Vert.x, we used Future objects. In this post, we are going to see another way to manage asynchronous code: reactive programming. We will see how Vert.x combined with Reactive eXtensions gives you superpowers.

Let’s start by refreshing our memory with the previous posts:

The first post described how to build a Vert.x application with Apache Maven and execute unit tests.
The second post described how this application became configurable.
The third post introduced vertx-web, and a collection management application was developed. This application exposes a REST API used by an HTML/JavaScript front end.
In the fourth post, we replaced the in-memory back end with a database and introduced Future to orchestrate our asynchronous operations.

In this post, we are not going to add a new feature. Instead, we’ll explore another programming paradigm: reactive programming.

Red Hat Summit 2018: Learn how other developers are producing cloud-native applications

By Mike Guerette and Rob Terzi April 17, 2018April 17, 2018

Want insights into how other organizations are building cloud-native applications and microservices? At Red Hat Summit 2018, developers from a number of different companies will be sharing their stories in break-out sessions, lightning talks, and birds-of-a-feather discussions. Learn how they solved real business problems using containers, microservices, API management, integration services, and other middleware.

Istio Dark Launch: Secret Services

By Don Schenck April 17, 2018April 16, 2018

“Danger is my middle name” is great for spies and people of mystery, but when it comes to deploying software, boring is better. By using Istio with OpenShift and Kubernetes to ease your microservices into production, you can make deployment really, really boring. That’s good.

[This is part seven of a ten-week series about Istio, Service Mesh, OpenShift, and Kubernetes. Part six can be found here.]

Boring Is Good

Not to worry, dear DevOps person; there are some exciting things in store for you. It’s just that the end result, thankfully, is boring. You want the fun of setting things in motion and then the routine of watching it just work.
