The emerging cloud-computing paradigm is rapidly gaining
momentum as an alternative to traditional IT (information
technology). However, contemporary cloud-computing offerings
are primarily targeted for Web 2.0-style applications. Only
recently have they begun to address the requirements of enterprise
solutions, such as support for infrastructure service-level
agreements. To address the challenges and deficiencies in the
current state of the art, we propose a modular, extensible cloud
architecture with intrinsic support for business service management
and the federation of clouds. The goal is to facilitate an open,
service-based online economy in which resources and services are
transparently provisioned and managed across clouds on an on-demand
basis at competitive costs with high-quality service. The
Reservoir project is motivated by the vision of implementing an
architecture that would enable providers of cloud infrastructure to
dynamically partner with each other to create a seemingly infinite
pool of IT resources while fully preserving their individual
autonomy in making technological and business management
decisions. To this end, Reservoir could leverage and extend the
advantages of virtualization and embed autonomous management
in the infrastructure. At the same time, the Reservoir approach
aims to achieve a very ambitious goal: creating a foundation for
next-generation enterprise-grade cloud computing.
