The system is not a passive network sniffing tool. It is active, using the Gomez network acquired in October 2009 to load-test various Internet web services and report in to CloudSleuth's central command. Gomez keeps virtual machines running in the various clouds to supply feedback on their service slowdowns and establish baseline latencies for their operations.

CloudSleuth has existed in beta preview since April. Compuware officials announced it was generally available Nov. 1, and the following day Mark Hillman, Compuware VP of strategy, told attendees at the Cloud Computing Conference & Expo in Santa Clara, Calif., that his firm was trying to provide "outside-in visibility across the entire enterprise-Internet delivery chain."

In effect, CloudSleuth grafts performance data on services outside the company onto application performance data derived inside the company. In the past, it's been possible through traditional systems management to know whether an application was running and whether it was experiencing slowdowns due to internal systems. But it was extremely hard to get a view of what impact Internet network segment latencies or a slowdown at a major cloud service provider might be having.

With Compuware's headless users working tirelessly around the world to sample those services, it's now possible to build a more complete picture and tell when end users may be seeing a slowdown.

CloudSleuth regularly tests the performance of three content delivery networks as well. They provide a network of Internet servers that host distributed content sought by users far from where the content originates. They are CDNetworks, Edge Cast, and Amazon Cloud Front.

But progress could still stall: 59 percent of nonusers ­distrust the security of Google's cloud. Its data privacy is an open question, and 37 percent worry about integration.
