The Utility Computing revolution apparently arrived in the form of AppLogic from 3tera.
Modern applications are complex systems comprised of the application software, web servers and databases, operating systems and drivers, numerous servers, storage for application data, switches, firewall, and the networks that connect it all. Deploying and operating these systems requires significant expertise and scaling complex systems is a not-trivial problem. Applogic is trying to address these issues:
Applogic starts with grid operating system that puts together standard servers to creates a single supercomputer. A grid can be built from commodity servers and may contain anywhere from 1 to 5,000 machines (so far, they claim they don’t know the effective upper limit).
3tera recently completed Grid Computing Benchmark Test along with dedicated server hosting provider Layered Technologies. The benchmark measurements show that Applogic really delivers performance.
An overall performance benchmark of 42,540 was achieved with the UnixBench WHT utility while consuming 443 CPUs. Based on the single CPU server result for the same benchmark of approximately 100, this implies that users can harness the equivalent of 420 single CPU dedicated servers through the utility computing service. This is no way represents the maximum performance of the system. During the benchmark we did not reach any fundamental architectural limit of the system, but ran out of hardware resources to add to the test.
Applogic makes very clever use of software virtualization, a process that can make almost any piece of Linux software or infrastructure hardware (Switches, Firewalls, Storage Arrays) and replicate them as a virtual appliance. A visual mapping tool allows the user to model complex IT application systems and transform them virtualized infrastructure — completely self-contained solutions that be propagated from one datacenter to another or seamlessly scale from a fraction of a server thousands of servers without reconfiguration.
We have yet to measure this Grid solution under real world tests, but the technology seems very promising
