Cloud Computing makes data truly mobile and a user can simply access a chosen cloud with any Internet accessible device. In Cloud Computing, IT-related capabilities are provided as services, accessible without requiring detailed knowledge of the underlying technology. Thus, many mature technologies are used as components in Cloud Computing, but still there are many unresolved and open problems. Security in the cloud domain is considered as one of the top challenges. Cloud and IT service providers should be responsible for the data of their customers and users. However, accountability frameworks for distributed IT services is current still absent and makes it difficult for users to understand, influence and determine how their service providers honor their obligations. It is important to support users in deciding and tracking how cloud service providers use their data. By combining methods of risk analysis, policy enforcement, monitoring and compliance auditing with tailored IT mechanisms for security, assurance and redress.
In any cloud service model, multiple stakeholders are involved. One service provider can be the consumer of another service. The complex stakeholder relationships require precise monitoring and accounting. Monitoring can be performed in multiple layers with different granularities. In the Infrastructure as a Service (IaaS) model, a customer has a set of virtual machine instances that are reachable by each other. Instances can be located in different geographical regions. A variety of technologies are capable of providing instances’ connectivity, including network virtualization. From the network monitoring perspective, distinguishing customers’ activities in the network is crucial. In this study an improved architecture of the networking service for cloud platform is introduced, using Software Defined Networking (SDN).
