Enterprise Usability of Cloud Computing Environments: Issues and Challenges

Cloud Computing Environments enable business agility and enterprises to exploit/respond quickly to changes in the marketplace, competition, technology and operational environment. For enterprises, CCE present a number of issues and challenges. Some of these include the inability to take advantage of the dynamic resource elasticity of CCE, issues of data fragmentation and duplication, the challenge of migrating transactional systems to a CCE, or the challenge of utilizing SaaS applications in conjunction with the other enterprise applications, say, to implement end-to-end process integration. Enterprises, also, have extended partnerships and aim to extend integration of participating systems. This paper presents some of these challenges and mechanisms to alleviate some of these challenges of operating and managing a hybrid CCE. The paper also presents mechanisms for robust network interconnectivity and partitioning mechanisms to co-isolate cooperating systems.
