Ubuntu provides versatile cloud images that can be utilized on various cloud deployment infrastructures. Eucalyptus’s euca2ools eustore tool makes it easier for cloud administrator’s to bundle, upload and register images on Eucalyptus clouds. Using eustore-install-image with Ubuntu Cloud images provides the best of both worlds – solid cloud images that can be easily deployed to […]
In my last blog, I covered three ways Eucalyptus Systems uses the Varnish-Walrus architecture. This blog will cover how eustore takes advantage of this architecture. Overview Eustore is an image management tool developed by David Kavanagh. Its primary goal is to automate image bundling, uploading and registration. The two commands provided by eustore is eustore-describe-images […]
Something that Eucalyptus has been constant about from the beginning is its stance on being the best open source, on-premise AWS-compatible cloud on the market.

In previous posts, I shared how to use Ubuntu Cloud Images and eustore with Eucalyptus and AWS. This blog entry will focus on how to use these assets to create EBS-backed EMIs in 12 steps. These steps can be used on AWS as well, but instead of creating an instance store-backed AMI first, Ubuntu has already […]
This blog post was driven by the need to make it easier to test Eucalyptus DNS in a lab environment. The goal was to have a scriptable way to add/delete fully delegated sub-domains without having to reload/restart DNS when Eucalyptus clouds were being deployed/destroyed. This was tested on an CentOS 6 instance running […]
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 […]
A few weeks ago, I posted a blog entitled “Fun with Varnish and Walrus on Eucalyptus, Part 1“. This blog will follow-up on my blog to showcase a few production use cases that utilize the Varnish–Walrus architecture built on top of Eucalyptus.*NOTE* This architecture can also be leveraged using AWS EC2 and S3. This is […]
