The key characteristic of cloud computing is provision of IT infrastructure and its applications as a scalable service. Since this environment is conceived service-oriented, service management and delivery of comprehensive architecture for this environment are important. To provide better services in cloud computing, any proposed architecture may be based on IT service management frameworks and reference models, to improve the management of services in cloud computing. Hence, IT service management reference models and frameworks are first compared in this paper and according to the comparisons; PRM-IT may be selected among other frameworks such as ITIL v3, HP, MOF as a more complete reference and used set forth in the operational section of the proposed architecture. Also, processes of the eTOM process framework are more complete than other frameworks while considering billing & revenue management as two critical modules in cloud based accounting Also. COBIT5 used in this architecture to enrich governance capability. On the other hand, a few of recent cloud architectures compared to find out current drawbacks and pitfalls and Finally , a comprehensive architecture is being proposed for cloud to provide a nearly more effective architecture resulted by composition of these frameworks in a wise layout. This architecture is in the context of SOA.
