Océano - SLA Based Management of a Computing Utility

Océano is a prototype of a highly available, scaleable, and manageable infrastructure for an e-business computing utility. It enables multiple customers to be hosted on a collection of sequentially shared resources. The hosting environment is divided into secure domains, each supporting one customer. These domains are dynamic: the resources assigned to them may be augmented when load increases and reduced when load dips. This dynamic resource allocation enables flexible Service Level Agreements (SLAs) with customers in an environment where peak loads are an order of magnitude greater than the normal steady state.
