A Community Cloud for a Real-Time Financial Application -Requirements, Architecture and Mechanisms

摘要

Nowadays, Cloud Computing is appealing for both IT businesses, which have a new opportunity to lower costs and expand its computing capacity, as for the scientific community, which has a scalable and elastic computer infrastructure at disposal. The research regarding cloud environments has been a theme of growing interest in the last few years as this new distributed computing paradigm poses challenges for both the application developers and the infrastructure providers. In this paper, it is presented a financial real-time application and a cloud architecture which can address the real-time requirements of this application through the adoption of real-time scheduling techniques. This architecture is based on the concept of a community cloud, where the participants share resources to each other dynamically in a decentralized manner.
