The ideal customer is one with an IT organization that is tasked with supporting a heterogeneous set of user groups (each with its own technology needs, business logic, policies, etc.) using infrastructure that it must maintain across different phases of the technology lifecycle.
There are two prevalent usage models that we observe regularly. The first is as a development and testing platform for applications that, ultimately, will be deployed in a public cloud. It is often easier, faster, and cheaper to use locally sited resources to develop and debug an application (particularly one that is designed to operate at scale) prior to its operational deployment in an externally hosted environment.
The virtualization of machines makes cross-platform configuration easier to achieve and Eucalyptus' API compatibility makes the transition between on-premise resources and the public clouds simple.
The second model is as an operational hybrid. It is possible to run the same image simultaneously both on-premise using Eucalyptus and in a public cloud thereby providing a way to augment local resources with those rented from a provider without modification to the application.
For whom is this relevant technology today? Who are your customers? Wolski: We are seeing tremendous interest in several verticals. Banking/finance, big pharma, manufacturing, gaming, and the service provider market have been the early adopters to deploy and experiment with the Eucalyptus technology.
