For IT professionals who are charged with the operation and management responsibilities for a data center, the self-service notion is appealing, but for many of them, it is not new. What is new is the speed with which such requests can be filled by on-premises cloud platform technology with NO system administrator intervention. We at Eucalyptus sometimes take for granted that the production cloud must be fast. We're occasionally surprised, however, by how important speed is to IT administrators and cloud users.
What's the difference between a virtualized data center and a data center managed as a production cloud? Even with technologies such as virtualization management tools, the provisioning time that users experience is still several days because the process is not automated and self-service. The Eucalyptus cloud platform can turn that time into about a 90 seconds for 100 nodes.
Eucalyptus cloud platform technology attempts to keep itself running "at all costs" which means simple functionality testing can mask intermittent internal problems. By observing the confidence bounds on the average times, it is possible to spot high-variance runs that may signal the presence of a transient bug even when the user requests are correctly satisfied.
We use performance testing to bolster our confidence in the software releases. The test numbers we were discussing are not even for an optimized installation. An on-premises production cloud can streamline IT by turning a virtualized data center into a hyper-fast data center.
