Secure and QoS aware architecture for cloud using software defined networks and Hadoop

Cloud services have become a daily norm in today's world. Many services today are been migrated to the cloud. Although it has its own benefits it is difficult to manage due to the sheer volume of data and the various different types of services provided. Adhering to the Service Level Agreement (SLA) becomes a challenging task. Also the security of the cloud is very important since if broken all the services provided by the cloud distributor are at risk. Thus there is need of an architecture which is better equipped with security as well as adhering to the quality of service (QoS) written in the SLA given to the tenants of the cloud. In this paper we propose an architecture which will be use software defined networking (SDN) and Hadoop to provide QoS aware and secure architecture. We will also use Kerberos for authentication and single sign on (SSO). In this paper we have shown the sequence of flows of data in a cloud center and how the proposed architecture takes care of it and is equipped to manage the cloud compared to the existing system.
