I installed Ubuntu Eucalyptus cloud (#UEC) on a couple of servers at home. I was naively expecting it to be similar to VMware. Oh I was wrong.
UEC is the Eucalyptus ‘cloud’ software running on Ubuntu servers. The instances would run under the KVM or Xen hypervisors. Ubuntu’s defaulted to running KVM but isn’t restricted by it.
“Eucalyptus is a software available under GPL that helps in creating and managing a private or even a publicly accessible cloud. It provides an EC2 compatible cloud computing platform and S3 compatible cloud storage platform…” Eucalyptus Beginner’s Guide
This is how a vm works in UEC:
You publish an image that you previously installed all the software you need (or you can download such an image). There can be as many instances of this image running as the hardware supports (spread across N number of backend Node Servers).
All instances are transient. As long as an image is running, it will have a physical presence.. but when it is shutdown, the instance is removed including any work performed in the instance.
“static” storage is available via a Storage Server. After you create an image but before you start it, you have the opportunity to attach storage to the instance.
While the management tools for UEC, and therefore Amazon EC2/EM, are primitive compared to VMware, it should be able to scale much higher with far less focus on which ‘virtual machine’ goes where.
Using VMware vCenter Converter and getting a SQL_CANTOPEN or similar error? Make sure your backup (Carbonite in my case) is disabled else it may try to backup the database for the converter and lock the files from being written to. Anyone know where VMware keeps this database?
If you’ve attended the Greater Chicago Jewish Folks Art Festival and took photos, please share your photos with the rest of the world! It doesn’t matter what year or if they’re fuzzy or overexposed.. we love all the photos 🙂
I just created the Flickr photo group Greater Chicago Jewish Folks Art Festival so everyone can share their photos from the Greater Chicago Jewish Folks Art Festival:
Flickr is almost certainly the best online photo management and sharing application in the world. Show off your favorite photos and videos to the world, securely and privately show content to your friends and family, or blog the photos and videos you take with a cameraphone.
