Security Challenges in Hybrid Cloud Infrastructures

Cloud computing has the potential to significantly change the way enterprises and their IT (Information Technology) systems run, but in order to achieve this the current cloud computing model needs to be changed according to the enterprise requirements. These modifications lead to the evolution of the hybrid cloud, which is a mix of both public and private clouds. Here, we consider hybrid cloud deployment and Infrastructure as a Service (IaaS) consumption model in detail since these provide the greatest flexibility for the enterprise users. In order to succeed with hybrid cloud approach, there are a few challenges that must be addressed such as application complexity and security. In this paper, we focus on the challenges and security issues which may arise in the enterprises due to migration of their IT infrastructure towards the hybrid model and finally analyze some of the solutions which helps in providing secure connectivity between the public cloud and the enterprise internal network.
