Frustrated by long delays getting new code into production? Worried that developers are adopting unapproved technologies? In an increasingly automated, containerized world it’s time to adapt your processes and policies so that developers can utilize the latest and most appropriate technology — and operations have full awareness of everything running in their environment.
The Problem and How to Solve It
IT processes, driven by business reliance on Mode 1 applications, have not been designed nor are equipped to handle rapid change. This creates friction between management and operations on one side, and developers on the other. For example, when developer teams want to employ new or different tools than the standards accepted by operations it often creates friction. It doesn’t have to be this way, though.
In this post, we are going to take a deeper look at the collaboration that happens between development and operations when building and working with the “latest and greatest” technology stack.

It’s been just over three years since Solomon Hykes presented the world with the (so far) most creative way to use the tar command: the Docker project. Not only does the project combine existing container-technologies and make them easier to use, but its well-timed introduction drove an unprecedented rate of adoption for new technology.
Did people run containers before the Docker project? Yes, but it was harder to do so. The broader community was favoring LXC, and Red Hat was working on a libvirt-based model for Red Hat Enterprise Linux. With OpenShift 2, Red Hat had already been running containers in production for several years – both in an online PaaS as well as on-premise for enterprise customers. The model pre-Docker however was fundamentally different from what we are seeing today: rather than enabling completely independent runtimes inside the containers, the approach in

The recent release of Red Hat Cloud Suite marked a new milestone for Red Hat and our customers. First, it is the first in what will become a family of suites. Second, it enables enterprise IT to transform their application development and operations toward an agile, innovation center based on hybrid cloud and devops technologies. Curating a broad set of open source technologies, Red Hat Cloud Suite offers a turnkey Cloud solution with a container-based app-development platform, private-cloud infrastructure, and a common management framework. Specifically, Red Hat Cloud Suite includes

Some time ago, two different projects were started in the open source community, namely: Ipsilon and Keycloak. These projects were started by groups with different backgrounds and different perspectives. In the beginning, it seemed like these two projects would have very little in common… though both aimed to include

In the past few years, virtualization admins have been hailed as heroes for enabling their organizations to significantly slash costs while improving service levels to the lines of business. Since the IT industry is constantly evolving, how can virtualization admins position themselves for success and avoid being rubber ducks in 2016? Below, we will look at 5 skills that should be in your toolkit in order to remain relevant in your organization.
1. Develop a deep understanding of how DevOps fits into your organization
According to Gartner, “By 2016, DevOps will evolve from a niche strategy employed by large cloud providers to a mainstream strategy employed by 25 percent of Global 2000 organizations.” Like many people, you might be asking yourself – what exactly does DevOps mean? DevOps is

It Started with Developers
Developers were the first adopters of containers for application creation. Now that containers have made their way into production environments, operations teams are starting to look deeper at what benefit they bring. Deployments are a key focus not just because the container model is so different, but also because there are automation integration points that have been previously unavailable.
Release engineers are faced with a tough question: continue to do rolling style updates as they always have or move to a red/black deployment model. Both have their pros and cons but using containers with red/black deployment methods provides

Over the last 18 months, especially since the general availability of Red Hat Enterprise Linux 7, “containers” have emerged as a hot topic. With the more recent introduction of Red Hat Enterprise Linux Atomic Host, an operating system optimized for running the next generation of applications with Linux containers, one might wonder… what about virtualization? In that the benefits of containerization seem to overlap those of traditional virtualization, how do organizations know when to pick one approach over the other?

What if you could run your existing Red Hat Enterprise Linux 6 applications on Red Hat Enterprise Linux 7 without porting or making changes to your source code? Today, we are pleased to announce the immediate availability of the Red Hat Enterprise Linux 6 platform image, which allows for the creation of Red Hat Enterprise Linux 6-based application containers. Applications that have been developed, tested, and certified for Red Hat Enterprise Linux 6 systems can now be deployed as a container and run on Red Hat Enterprise Linux 7 as a container host.
This new platform image allows customers to

Were you able to attend the Red Hat Enterprise Linux roadmap session at this year’s Red Hat Summit? If not, I have some good news – the slides are still available (here). In addition, many of the questions that were asked after the presentation were recorded, sorted, and answered… and are now posted on the Red Hat Summit Blog. Of note:
