Production deployments of Eucalyptus, like production deployments of any infrastructure software running in a data center, require some amount of health and status monitoring be happening in order to both allow the Eucalyptus/data-center administrator the ability to stay on top of evolving resource situations and to provide invaluable diagnostic information when something is going sideways within the resource pool.  Fortunately for all of us, there exists a wide variety of health/status...

Eucalyptus 3.2 introduces a new user console, better troubleshooting and logging, better reporting and support for EMC VNX SAN arrays.

A lesser known fact is that the EBS implementation in Eucalyptus 3.2 no longer requires loop devices. In 3.2, we open sourced a new driver called DASManager, which stands for Direct Attached Storage.

Recently, I saw a really cool study of the costs that companies incur when using public clouds in a "Big Data" context. The cost data is certainly interesting, but I was more intrigued by what the presentation had to say about cloud usage, particularly with respect to big data.

At the end of last year, we (Eucalyptus) released version 3.2 which included our user console. This feature finally allowed regular users to login to a web UI to manage their resources. Because this was our first release, we had a lot of catching up to do. I would say that is still the case, but the point here is that we were able to test all of our features against Eucalyptus. As we add features to the user console which are currently under development in the server side, we must have the...
