The ARM Arc

ARM.  When used in a sentence it may refer to the company (ARM Holdings), one of its numerous CPU versions, or even a way of life.  But we just call it ARM.  ARM (the company) creates low power processor designs which they license to other companies to implement; Licensees enhance ARM’s design and manufacture the actual chips.  The resulting processors are the defacto standard in the fiercely competitive consumer mobile space of tablets and cell phones.  Of course, the thing that makes ARM interesting to Red Hat isn’t consumer mobile, it is evaluating their potential in servers.  In theory if they perform well, their low-wattage designs might be quite compelling.

Dude, where’s my PaaS memory? Tuning Java’s footprint in OpenShift (Part 2)

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 copies of a named file
  • deletion of the whole cache

Repost: Node.js – An Enterprise Situation Report | The New Stack

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 system level virtualization with hot new technologies like Docker, Node.js and the army of JavaScript coders are pushing forward with new offerings, products and projects that make enterprise adoption a no-brainer.

Dude, where's my PaaS memory? Tuning Java's footprint in OpenShift (Part 1)

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 deploying web services. One of the OpenShift team’s goals is to maximize the number of guest Java EE deployments on any underlying physical host. However, in the first release of OpenShift meeting this goal was challenged by the high physical memory use observed in many of the deployed JVMs. With only so much memory available on any given physical host the more memory each JVM uses the lower the density of guest deployments.

Repost: Going Atomic with the Red Hat Enterprise Linux 7 High-Touch Beta

Excerpts from the original article:

“Now that Red Hat Enterprise Linux 7 is generally available, we are re-casting the Red Hat Enterprise Linux High Touch Beta program into a series of Red Hat Enterprise Linux 7 special interest groups (SIGs), the first of which is focused on application containers. The Red Hat Enterprise Linux Atomic Host SIG encompasses technologies that are required to create, deploy, and manage application containers.

Repost: Red Hat and Google Collaborate on Kubernetes to Manage Docker Containers

Excerpts from the original announcement:

“Red Hat and Google are both committed to open source and we were both early proponents of Docker as well as key contributors to the Docker project. We are now joining forces to drive a new open standard around orchestrating Docker containers at scale for the management of cloud application deployments.
