Continued from part 1. The test web service The test web service implements a simple file cache storing up to 10 copies of any given named file. Uploading copies beyond the 10th one causes the oldest version to be discarded. The server supports a variety of requests allowing a new version of a file to be uploaded an existing file version to be downloaded listing of the name and version counts of all files in the cache deletion of all...

I found this interesting Node.js article from The New Stack. A handy piece for those of you considering Node and especially now that we now have it in both Software Collections and OpenShift. "Why Node.js is an excellent and underutilized enterprise tool "Node.js, after cutting its teeth for a few years in the open source space, then being used by large-scale startups like LinkedIn and Joyent, it is now heading for the enterprise. From scaling virtualized hyper visors to operating...

Is Java really greedy for memory? Java is often blamed for being an over-hungry consumer of physical memory. Indeed, until recently our OpenShift team were tempted to draw this same conclusion. OpenShift is Red Hat's open source Platform as a Service (PaaS) product. You can access it via public Cloud infrastructure managed by Red Hat (OpenShift Online) or even deploy it to your own data centre/private cloud (OpenShift Enterprise). OpenShift Online provides simple and manageable scalability to anyone developing and...

Three Things Developers Need to Know | Openshift Blog.

Another excellent OpenShift Enterprise update with more examples of Red Hat Software Collections being converted into OpenShift cartridges: MySQL 5.5 and PHP 5.4, and soon the additions of Python 3.3 and MongoDB 2.4. Also, I love the "simple, no touch virtual machine (VM) image of OpenShift Enterprise so [customers] can place the image on their laptop and work on cartridges, code, and DevOps models while they are disconnected from their datacenter. As part of your OpenShift Enterprise subscription, we have...

"Since we launched our award winning OpenShift Online public Platform-as-a-Service (PaaS) service three years ago and OpenShift Enterprise private PaaS in 2012, customers have often asked us, “What about Microsoft .NET apps on OpenShift?” We listened, and are excited to announce that we are collaborating with Uhuru Software to bring Microsoft .NET and SQL Server capabilities to OpenShift, as an open source community-driven effort in OpenShift Origin. OpenShift Origin is the upstream community project that drives innovation for both our...

The OpenShift Online release for January 2014 has some great additions! Read the whole article here, but read about these cartridge updates: "We've updated some of our most popular cartridges to newer versions. Plus, we'll have more coming very soon. PHP 5.4 MySQL 5.5 Python 3.3 Zend Server 6.1 with PHP 5.4 " Each of these technology cartridge updates are provided by Red Hat Software Collections--fully maintained and supported by Red Hat."

DeveloperWeek 2014 Innovator awards have been announced and Red Hat has garnished two of them: 1. Platform-as-a-Service: Red Hat OpenShift 2.

Here's a list that highlights top OpenShift blogs of the year! via OpenShift's Top 10 Posts of 2013 | OpenShift by Red Hat.

Came across this post on the Red Hat Services blog about some solid practices for "doing" DevOps. I liked Mr. Hoffman's simple explanation of what DevOps is. I also liked that he points out how just using a tool (or a set of tools) does not equal "doing DevOps." Check it out and make sure you leave some comments here or there about what you think.

Announcing OpenShift Enterprise 2.0 | OpenShift by Red Hat. In case you missed this last week - Red Hat Software Collections are becoming cartridges in OpenShift. " Cartridge Upgrades: As a leader in both operating system development and middleware solutions, Red Hat is in a unique position to provide some amazing content to PaaS users, which are integrated as OpenShift Cartridges.

Red Hat Developer Toolset v2.0 was released earlier this year and has received some great feedback from developers, which is always great to hear. But perhaps you'd like to see Red Hat Developer Toolset in action rather than reading about it. If so, here's a recording of a live demo showing you some of the great new features, including the option to create and deploy your C++ application to Red Hat OpenShift from right within the Eclipse IDE. In addition...

I've recently released a tool called vm-truck-loader to automate virtual machine creation with VMware vCenter. Using a simple CSV file, and leveraging the API exposed by vCenter, this Java based command line tool enables you to design a fully automated deployment process, and can be a key to implement a proper Standard Operating Environment around vCenter. In this regard, I thought I'd do a quick entry on this blog, to briefly describe what the tool can do. Instrumenting virtual machine...

Some months ago, I developed and released a small Puppet module for tuned-adm. As this tool is a nice feature of RHEL, I think it is only fair from me to advertise about it here, on the Red Hat developer blog. Quick overview of 'tuned-adm' (Photo credit: Accretion Disc) To make this brief, this command will take care of tuning the operating system for you, based on the usage you want to make of it. For instance, if you want...

We will start by teaching you the meaning behind some acronyms you see thrown around - IaaS, PaaS, and...

Background The goal of this article is to use the OpenShift Platform as a Service (PaaS) as a learning platform for Django. Most of the technical articles out there about running Django on OpenShift assume the user already understands how to administer Django environments and projects. This article is written from the perspective of someone who has done some python programming and wants to learn some Django without doing a bunch of setup work. Since each OpenShift Gear "...is a...
