Message Protocols for Provisioning and Usage of Computing Services

Abstract. The commercial availability of computational resources enable consumers to scale their applications on-demand. However, it is necessary for both consumers and providers of computational resources to express their technical and economic preferences using common language protocols. Ultimately, this requires clear, flexible and pragmatic communication protocols and policies for the expression of bids and resulting generation of service level agreements (SLAs). Further standardization efforts in such description languages will foster the specification of common interfaces and matching rules for establishing SLAs. Grid middleware are not compatible with market-orientated resource provisioning. We aim to reduce this gap by defining extensions to a standardized specification such as JSDL. Furthermore, we present a methodology for matchmaking consumer bids and provider offers and map the additional economic attributes into a SLA. We demonstrate the usage of the message protocol...
