Cloud computing is currently the ‘in buzz word’ in computing. But what is cloud computing? Cloud computing radically changes the way computer applications and services are constructed, delivered, and managed. Cloud computing provides a new potential for corporate, enterprise and academic computing to consolidate their data and services over the WWW so that (approved) anyone-anywhere-anytime access is possible. Cloud computing shares the same original vision of grid computing articulated in the 1990s by several researchers, however, there are significant differences also.


Large data centers permit resource sharing across various applications, which leads to possible economies of scale at the hardware and software levels, whereby they can be hosted over a common platform that is available to everyone. Software services that can obtain seemingly infinite scalability and services level is now possible. Incremental growth to meet customers’ varying demands is also possible. Several types of costing models, rapid provisioning and availability lead to more efficient resource utilization and reduced cost for utilization. Therefore, NEW TECHNIQUES for managing shared data in the cloud, fault-tolerance mechanisms, service composition, scheduling, metering and billing, protecting privacy, communication, and, more generally, sharing resources among applications under the control of diverse organizations, ARE NOW REQUIRED.


In this talk, I will detail what is Cloud Computing, challenges and opportunities in cloud computing, underlying technical issues in cloud computing and the dark side of cloud computing. In particular, I will detail several security data, information and knowledge related security issues that need to be tackled when working with cloud. Specifically, issues such as, mechanism for storage and/or usage of data, encryption/decryption mechanisms, custodial policies, legal protections, and many other areas would be dealt with. Some underlying security issues on the use of cloud over a smart grid environment will also be introduced. The deployment of artificial intelligent agents to manage such diverse security issues would also be considered in this talk.


And, iff time permits, I will also provide cloud computing applications to several areas which include, but not limited to, information management, intelligence and value-adding thru’ information extraction, process flow & workflow analysis, organiogram generation, economic analysis, medical & pharmaceutical intelligence, just-in-time management of health, manufacturing, environment. I will also give some examples of cloud computing to web intelligence (social network and mobile network). However the multi-million dollar questions include, “Are you safe? Is your privacy Protected? Ethical & Legal Issues?” I will conclude the talk with some grand challenges that is inherent in Cloud Computing.

Keywords: Cloud computing, Research issues and challenges in cloud computing, Lessons from distributed systems, peer computing and grid computing, Security issues in cloud computing, Approaches to solutions.
