Recently, I had the opportunity to sit in on a few meetings at Eucalyptus Systems, Inc. discussing Elastic Load Balancing implementation ideas for Eucalyptus 3.3.  Elastic Load Balancing is under the “Future Development Directions” on the Eucalyptus Cloud Roadmap.  Part of my involvement was to evaluate the Zen Load Balancer.   The first question that I [...]

One of the most common questions I’ve heard asked from Eucalyptus users is this one: “how easy is it to convert an AMI to an EMI?” And the answer is: not as easy as it should be.

We’ve got some process guidelines on our wiki, thanks to Tim Gerla — but we should have the ability to do much of this automagically.  So that’s the tool I’ve started work on.  In the spirit of “release early release often”, I’ve uploaded a very early iteration of this tool.  Find the brand new Github repo...

I'm happy to see Release 3.2 of Eucalyptus see the light of day because it signals an important shift in the adoption cycle. Users and IT administrators now depend on Eucalyptus for their businesses and, as a result, it needed to be easier to use and with which to live. In the 3.2 release, Eucalyptus includes a number of features that make it friendlier to its users and and administrators.

When we started to develop Eucalyptus, we decided early on that we would make it work before...

If you are building out your internal Dev & Test capabilities, Eucalyptus 3.2 may be just what you need. In a few weeks we are officially releasing version 3.2 which has been available through nightly builds for the enthusiastic user community for some time. The new version has been toughened on the inside and softened on the outside. All in all, here is an open source cloud platform for which agility is a key ability.

Agility means that you can undertake bigger changes faster...

In this article, I will go over the technical details on how in Eucalyptus, we used Selenium to simulate a large number of cloud user workload in order to ensure the quality of user experience in the new Eucalyptus user console.

As covered in my previous blog, Eucalyptus is coming out with a new user console, that is browser-based and intuitive to use, thus playing a key role in promoting the cloud adoption among IT organizations and enterprises.  But, the challenge was to...

Background

In a Eucalyptus HA configuration there are two Cluster Controllers’s (CC) which
are in an active-passive state. One is in “ENABLED” mode and one is “DISABLED” mode.
If a failure occurs, the active CC services moves to the secondary CC system.

If you combine this with Eucalyptus MANAGED or MANAGED-NOVLAN networking
configuration with a private back-end network your Node Controllers (NC) will require a
default gateway for access to external networks...

Reblogged from Greg DeKoenigsberg Speaks: We’re big fans of the Cobbler project here at Eucalyptus.

We’re big fans of the Cobbler project here at Eucalyptus. We think it’s the best tool in the open source world for bare metal provisioning.  We’ve invested in a gigantic QA environment for continual integration testing, and Cobbler is one of the linchpins of that environment. It’s the kind of tool that’s best appreciated by sysadmins who deal with *a lot* of systems.

I’m sort of attached to Cobbler personally, since I watched it grow out of Red Hat’s Emerging Technologies team several...
