On Wednesday April 25th, Eucalyptus will be hosting our first EucaDay. It’s a friendly little gathering of customers, partners, and community, and it’s free to attend. If you’re in the New York City area, you can register right now.

Of course, not everyone will be able to make it to New York City for this event. That’s ok, too — you can still attend and participate. For the sessions led by Marten Mickos (head honcho), Tim Cramer (lovable despot of engineering) and myself (community...

In my last post I detailed using screen as a teaching tool.  In this post I will go over using IRC to augment the demonstration with lecture/Q-and-A sessions and using a bot to record your sessions.  This post will deal specifically with setting up your own IRC service.

Since this is in parallel with EucaSchool, I should say that we don't use our own IRC server for EucaSchool.  We use  You can join us in our channels there: #eucalyptus for general support on Eucalyptus or...

Chef is a tool used for configuration management of bare metal and virtual systems. Chef has a client/server model as well as a standalone tool that is very similar to the tools from Puppet Labs. (Want to automate a puppet agent installation? Check out my earlier blog post

When using the cloud and launching multiple instances with the same job, configuration management is a huge time saver. Configuration management systems will allow you to build the configuration once and use it to...

In March, we announced an agreement to collaborate with Amazon Web Services (AWS) to ensure API compatibility between AWS and the Eucalyptus open source on-premise Infrastructure as a Service (IaaS) platform. Beyond the details of the news, I'd like to shed some light on how I think this agreement helps customers focus on the larger discussion of the policies and business logic that govern application workloads.

For some time now, Eucalyptus users have implemented application...

The cloud world has been quite the spectacle lately.  Intrigue, romance, alliances and double-crosses, comedy, tragedy, and zombies.  If you’ve seen the play already, I won’t bore you by recounting it — and if you haven’t, I won’t ruin it for you.

At Eucalyptus, we continue to care most about, and focus chiefly on, making open source cloud software that works for our users.  So let’s set aside the theatrics and talk about users for a moment.

Some of you may be familiar with the...

With the agreement between Eucalyptus and Amazon to cooperate on ensuring API fidelity between the two technologies comes the question of defining what it means for two independent implementations to support the same API. The API itself consists of a large number of different "commands" or "service requests," each of which triggers many different operations within the system that are visible to the user. Moreover, the API makes specific assumptions about "things" (VMs, storage volumes,...

Amazon Web Services (AWS) and Eucalyptus Systems announced an agreement last week that enables customers to more efficiently migrate workloads between their existing data centers and the AWS cloud while using the same management tools and skills across both environments.

With this agreement customers have the added flexibility to more freely move workloads between their existing IT environments and the AWS cloud. In addition, customers can take advantage of a common set of API’s that...

HA with OpeniSCSI:

Further to my general musings about HA, good chum Harold Spencer and I have been working on providing a way for our users to achieve high availability in the storage controller components of Eucalyptus for those who don’t have the SAN adapter.  The storage controller is the Eucalyptus component which handles the EBS (Eucalyptus Block Storage) volumes for instances.

Let me give some background here …..

With 3.0, we’re still following our old business...

In my previous job, I spent a fair amount of time with enterprise customers who were – more often than not – moving from proprietary Unix to Linux.  Coming from Unix, these customers were often heavy users of resource(or service)-based High Availability (HA) products; such as HP Service Guard, Sun Cluster, Veritas Cluster Server etc.  When moving to Linux, they wanted feature parity with their traditional Unix HA technologies and they ran very Enterprise-level workloads; like database, CRM,...
