My colleague Thierry Carrez just posted a blog this weekend discussing the new autoregistration features of the Ubuntu Enterprise Cloud that are coming up in Ubuntu 10.04LTS Server Edition.
"Part of the improvements coming up for Ubuntu Enterprise Cloud in 10.04 is the support for automatic registration of Eucalyptus components, even for complex topologies. In 9.10, we only supported local registration of components on a “CLC+Walrus+CC+SC” system, and you had to manually register NCs.
In 10.04, components installed through the UEC installer will automatically register themselves with their parent component, even on remote machines and complex topologies. Here is how it works."
