Ansible + AWS, Red Hat Enterprise Linux, and JBOSS

Many of the questions we frequently get are related to deploying applications and stacks into Amazon Web Services. Back in July, Ansible Government teamed up with partner DLT Solutions to host a webcast demonstrating the creation of a Red Hat stack in AWS entirely managed with Ansible. Watch it now and continue reading below for more information.

IT organizations look toward AWS for a number of reasons, but according to IDC, deploying applications in AWS results in a 64% lower TCO and 82% less downtime. Now let’s be honest. Who doesn’t like less downtime?

Red Hat is the leading Open Source provider for infrastructure and middleware solutions. Their industry-standard Red Hat Enterprise Linux and JBoss middleware are widely deployed in on-prem physical and virtual environments, and are the benchmark for stability, security, and performance.

But how can you leverage that power in AWS? With Ansible, it’s easy.

In the webcast, we demonstrate the deployment of a complete JAVA-based web application, including RHEL, JBOSS, and a load balancer. Once installed, we demonstrated how to use the same playbook that deployed the application to update the application. Better yet, these examples are available for you to start using and experimenting with today.

Easily provision Windows instances in AWS with Ansible

Untitled_designMYTH: using Ansible to do fully-automated provisioning of Windows instances in AWS is difficult, because WinRM is not enabled by default on Amazon’s Windows AMIs, and the admin password is not known at startup.

I’d like to bust this myth once and for all. As an Ansible Solutions Architect, I often see users going to great lengths to solve both of these problems. The solutions I’ve encountered in the field have ranged from “minor maintenance hassle” to “major code-smell”, and are usually completely unnecessary; an obscure EC2 feature called User Data can replace them all. In a post on my personal blog, I demonstrate a basic use of this feature to manually provision Windows instances that are Ansible-ready on first boot, using unmodified Amazon-provided AMIs. A follow-up post expands that technique into a fully-automated provisioning sample. Try it yourself to see how easy it is to quickly spin up and configure Windows instances for any need, using only Ansible!

Checking Out GitHub Pull Requests Locally

In this post, I’m going to show you how to use the Git command-line to check out GitHub pull requests locally. I take absolutely no credit for this trick! I picked this up from this GitHub Gist, and merely wanted to share it here so that others would benefit.

The GitHub gist shows you how to modify the Git configuration for a particular repository so that when you run git fetch it will fetch all the pull requests for that repository as well. This is handy, but what I personally found most helpful was a comment that showed the command to fetch a specific pull request. The command looks like this:

git fetch origin pull/1234/head:pr-1234

Let me break that command down a bit:

  • The origin in this case refers to the Git remote for this repository on GitHub. If you are using the fork-and-pull method of collaborating via Git and GitHub, then you will have multiple Git remotes—and the remote you want probably isn’t origin. For example, if you want to fetch a pull request from the original (not forked) repository, you’d want to use the name that corresponds to the Git remote for the original repository (I Continue reading

VMworld 2015 Day 2 Keynote Liveblog

The day 2 keynote kicks off with another Cloud Academy presentation… After the video wraps up, Sanjay Poonen takes the stage. Poonen briefly recaps yesterday’s messaging, and then moves into the focus of today’s keynote—focusing on the “any application and any device” part of the “Ready for Any” messaging.

According to Poonen, the core of the solution for “any application on any device” is VMware’s Workspace Suite. Workspace Suite creates the magic of “enterprise computing with consumer simplicity.” How? It starts by building upon the core of virtualized infrastructure, made possibe by VMware’s compute, storage, and network virtualization solutions. Combined with a strong management layer and hybrid cloud solutions, this becomes the software-defined data center (SDDC). Somehow, though, this stuff needs to be connected to the end users—via desktop, mobile, content collaboration, and tying it all together with identity management. Poonen points to innovation in all of these areas.

Obviously, mobile is a category that is growing very rapidly, and Poonen talks about VMware’s movement in this space via the AirWatch acquisition. And the use of mobile devices is also key to VMware’s identity efforts as well. Poonen shows a video with a few customer testimonials, and then introduces Continue reading

This is a liveblog for the Day 1 general session at VMworld 2015 in San Francisco. For many people, VMworld started yesterday with the Welcome Receptio in the Solutions Exchange, but today marks the official kick-off to the event. I’ll have to end this liveblog shortly before the general session ends in order to make it to some customer meetings.

The keynote kicks off with a short video about the VMware Cloud Academy, where both “legacy” and “cloud-native” apps can enjoy the Unified Hybrid Cloud. Following that video, Carl Eschenbach takes the stage (along with some “apps”). Eschenbach sets the stage for the session by talking about the momentum and volume of success that VMware has enjoyed (and continues to enjoy). He also calls out VMware’s philanthropic efforts, via the VMware Foundation and the #vGiveBack program.

Eschenbach nexts dives a bit deeper on the theme of the show, “Ready for Any.” This means VMware technologies and products supporting any application, any cloud, any infrastructure, any time, any place…you get the idea. This theme encompasses SDDC (software-defined data center) initiatives, mobility initiatives, and EUC (end-user computing) initiatives. Eschenbach talks in a a bit more detail about how Unified Hybrid Cloud Continue reading
