Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources(network, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Trust and security have prevented businesses from fully accepting cloud platforms. To protect clouds, providers must first secure virtualized data center resources, uphold user privacy and preserve data integrity. The authors suggest using a trust-overlay network over multiple data centers to implement a reputation system for establishing trust between service providers and data owners.
