Contribution to cloud computing security architecture

Cloud computing security is an important problem when deploying its services. Users consider security to be the most important aspect when deciding to utilize a service cloud computing. Architectural views of cloud computing are views of stakeholders that have different roles and thereby responsibilities for implementing security mechanisms. Security belongs to cross-cutting aspects and pass over all layers of architecture. The Reference Architecture of cloud computing according to ITU-T Recommendation X.1601 specifies only basic security mechanisms and does not determine security responsibilities to roles in relevant services. Considerable division of responsibilities is in IaaS - Infrastructure as a Service. Responsibility for the security of some layers of architecture is on the service provider and the service customer as well. The division of responsibilities based on their requirements is solved in the article as the security architecture framework.
