Red Hat Developers and author N. Harrison Ripps have just released the first pieces of a ten-part series ("That app you love") in which Harrison describes the process of deploying an application using containers into a clustered environment on the cloud. Using the ZRC IRC client as a sample application, Harrison demonstrates each step in the process of containerizing software, dealing with issues like statelessness, security, and robustness that are typically architectural hurdles for most development teams moving to a...

In order for businesses to stay agile, developers must be able to deploy apps -- quickly, efficiently, and in a streamlined manner. Red Hat Open Innovation Labs uses a container-driven application development framework to perform continuous delivery and accelerate innovation. In this video, I’ll give you a peek into some of the work we at Labs are undertaking to accelerate application development. Specifically, I’ll walk you through the steps to create a deployment pipeline in Jenkins using the JBoss TicketMonster...

One of the greatest advantages of using docker containers is the fact that you can move them between environments. A promotion from Development to a Production environment, shouldn’t take more than some few seconds. This is one aspect of “Continuous Delivery” Because Microservices Architectures are “independently replaceable and upgradeable”, they are the best scenario to show a “Deployment Pipeline”. Red Hat Developers has produced a sample and free application called “Red Hat Helloworlds MSA” that demonstrates different aspects of microservices...

The last 4-5 years have seen the debut of many new software products specifically targeting both infrastructure services and IT automation. The consumerization of IT has caused its architects to take a fresh look at their existing, often times monolithic apps and IT infrastructure and asking: Can we do better? How do I keep IT relevant? How do I keep track of all these VMs and data? How do I scale out my IT environment without a huge budget increase...

JBoss Enterprise Application Server 7 has been out since June, and if you build and deliver using a Java EE environment and haven’t yet upgraded to EAP7, it’s time to make the jump. Here’s a look at what’s new in JBoss EAP 7, what has changed since JBoss EAP 6, and how to get the most out of JBoss EAP 7 as your Java EE7 server. Overview JBoss EAP 7 is bassed on WildFly Application Server 10, which provides a...

Over the last couple of weeks, I've been working on some Red Hat JBoss BPM Suite workshop material. One part of the workshop is a four-hour lab that guides the attendees through the development of JBoss BPM Suite 6.x processes, rules and applications (note that this workshop is available to our customers, please contact your Red Hat account manager or local Red Hat sales representative for more information), but I'm going to be sharing part of the story with you...

Note: This post is from 2016. For current instructions, reference the documentation. https://docs.ansible.com/ansible/latest/index.html https://docs.ansible.com/ansible-tower/ With DevOps taking hold in businesses ranging from small design agencies to large enterprises, there has been a real push to automate deployments and make them consistent. As part of this, maintaining configuration as code and utilizing a version control system such as Git or Subversion to house it is becoming more prominent. Tools like Puppet and Chef have been around for a number of years...

From a developer’s perspective, “incident management” can be a pretty ambiguous term. While the first thing that comes to mind is receiving and responding to alerts, most IT professionals know it is so much more than that. Effective incident management starts with data collection and continues through alerting, escalation, collaboration, and resolution. At the server level, the most important pieces of incident management are infrastructure monitoring and log management, the vast majority of which are easily configurable on a Red...

Around this time last year, Fedora 22 brought a major update for anyone working under the Fedora hood -- Yum was deprecated and replaced by DNF. It brings some significant changes: Faster, more mathematically correct method for solving dependency resolution A “clean”, well documented Python API with C bindings & Python 3 support Isn’t this a Release by Another Name? No, DNF marks a shift, and not just a fork to Python 3, C support and cleaner docs. The move...

If you like pipelines—specifically the kind that facilitate continuous software delivery, not the ones that drain stuff from your kitchen sink—you'll love Jenkins 2.0. Pipelines-as-code are one of the headline features in the latest version of Jenkins. Keep reading for more on pipelines and other cool enhancements in Jenkins 2.0, and how you can take advantage of them. Jenkins 2.0: New Features Outline Released in April, Jenkins 2.0 is the much-updated version of the open source continuous integration and delivery...

Ansible serves as a great tool for those system administrators who are trying to automate the task of system administration. From automating the task of configuration management to provisioning and managing containers for application deployments, Ansible makes it easy. In this article, we will see how we can use Ansible to provision Vagrant boxes. So, what exactly is a Vagrant box? In simple terms, we can think of a vagrant box as a virtual machine prepackaged with the development tools...

The charter of Open Innovation Labs is to help our customers accelerate application development and realize the latest advancements in software delivery, by providing skills, mentoring, and tools. Some of the challenges I frequently hear from customers are those around Platform as a Service (PaaS) environment provisioning and configuration. This article is first in the series of articles that guide you through installation configuration and usage of the Red Hat OpenShift Container Platform (OCP) on Amazon Web Services (AWS). This...

Situation: You’re a great software developer and a fearless leader. Your CEO bursts into your cubicle and he is giving you vast amounts of investment capital, no data center, and limited staff. Your task: build a multi-region, highly available presence in AWS (or your favorite cloud provider) that can be maintained by minimal man-power. Your multi-tier Java EE app is almost ready. You are going to be required to create, maintain, and monitor a large amount of servers, RDS instances...

As far as automated configuration management tools go, Ansible is “the new hotness” on the market. I admit, I am pretty new to Ansible. Until recently, the majority of my configuration management experience has been rooted solely in Puppet. Tack onto that my recent foray back into the world of Red Hat and I have a lot to learn, starting with getting Ansible installed and running on RHEL. There are two ways to install Ansible—via yum, or directly from source...

This year’s middleware keynote address at Red Hat Summit talked about microservices, the power of the pipeline, and how developers and devops can work together to release code to production at a much higher rate. The keynote also demonstrated how releases can be shipped so you can switch from the existing deployment to a new deployment (blue/green deployments), and demonstrated how to roll out a canary deployment to a subset of users to test out new features. (If the canary...

In a previous post, where-have-all-my-subscriptions-gone, I mentioned that you can access the Red Hat Content Delivery Network (CDN) using its API --- allowing you to query CDN for subscriptions and their usage, registered hosts, and more as well as unregistering hosts, and more. I wanted to do some analysis for my own subscription usage, so I wrote some scripts that let me more easily tell where my subscriptions are being used. Since Python scripting is still fairly new to me...

https://www.youtube.com/watch?v=o9EoWqiKLik It's amazing how you can have the feeling of being home when you arrive at some special places: people you love, food you love, and the warming sensation of being welcome. Without any doubt we from Red Hat Developers can assure that TDC São Paulo, with this amazing developer community, feels like home. From July 5th to July 9th we had the companion of more than 4800 developers at Anhembi Morumbi University, venue of the The Developer's Conference (TDC)...

Microservices are standing at the " Peak of Inflated Expectations". It's immeasurable the number of developers and companies that want to bring in this new development paradigm and don't know what challenges they will face. Of course, the challenges and the reality of an Enterprise company that has been producing software for the last 10 or 20 years is totally different from the start-up company that just released its first software some months ago. Before adopting microservices as an architectural...

If you are using JBoss Enterprise Application Platform (EAP) for J2EE development, the CloudBees Jenkins Platform provides an enterprise-class toolchain for an automated CI/CD from development to production. The CloudBees Jenkins Platform now supports integrations with both Red Hat JBoss Enterprise Application Platform (EAP) and Red Hat OpenShift across the software delivery pipeline. This enables developers to build, test and deploy applications, with Jenkins-based continuous delivery pipelines in JBoss via JBoss EAP 7 or JBoss EAP 7 on OpenShift. The...

JBoss EAP 7 was recently released, and brings with it a whole host of new features and support, such as support for Java EE 7, reduced port usage, graceful shutdown, improved GUI and CLI management, optimizations for cloud and containers, and much more. EAP 7's small footprint, fast startup time and support for modern Java and non-Java frameworks make it uniquely suitable for deployment onto PaaS cloud environments, and Red Hat happens to have a leading one: OpenShift. I put...

One of the core drivers behind modern application architecture, development and delivery methodologies like micro-services, agile and CI/CD is the ability to automatically test any software artifact, from application code to server configuration. Automated testing gives us the reliable, repeatable, assurance that our software meets the required quality with respect to aspects like functionality, performance, and scalability and is ready to be deployed in production. Why should testing of a business-process defined in BPMN2, a deployable software artifact, be any...

Following my introduction blog about why microservices should be event-driven, I’d like to take another few steps and blog about it. (Hopefully I saw you at jBCNconf and Red Hat Summit in San Francisco, where I spoke about some of these topics). Follow me on twitter @christianposta for updates on this project. In this article we discuss the first parts of carving up a monolith. The monolith I’m exploring in depth for these articles will be from the Ticket Monster...

Over the years, I've come across many command line interfaces ( CLI) to larger applications, each with varying levels of access and power. Having a CLI at all is a great first step for an application, as it opens up a much wider range of possibilities: administration, extension, and trust. CLIs also promote scriptability - the ability to create and maintain repeatable scripts, and the easier it is to develop said scripts, the better. Sometimes scripts can solve issues that...

I'm sure you have heard and read a lot about microservices in the recent past and how they are here to defend our end users from the horrible monolith. Breaking an application up into many components is a great start, but to take your organization to the next level requires a platform focused on integrating microservices into your continuous improvement process. Red Hat's James Rawlings & James Strachan led us through achieving our new goal of continuous delivery with containerized...

WildFly Swarm 1.0.0.Final was released this week at DevNation. It allows the developer to package his application and a JavaEE runtime in a "fat- jar" file. To execute the application, the developer will only need a Java SE Runtime installed and have access to the "fat-jar". No other downloads or configurations are needed. Besides being a well known (and consolidated) Java EE runtime, WildFly Swarm is also an excellent choice for Cloud-native Java apps through the "built-in support for third...
