As presented in the next figure, cloud computing is the current phase of the evolution row after grid computing. We cansee that every decades we have new computing terminology. Therefore, in few years (around 2015)we will face the next phase of computing. At the end of this blog I will predict what is the next computing phase.
As presented in the figure, there are challenges in every phase. Those challenges are inherited from the previous phase. Therefore, cloud computing has the largest challenges so far.
Cloud computing is a new computing paradigm, involving data and/or computation outsourcing, with
That is, use as much or as less you need, use only when you want, and pay only what you use
From the users/clients point of view, security is the main concern in cloud computing (see the next survey result). However, from the inventors point of view, I believe that the main concern is performance and scalability.
I list now the main challenges for could systems and especially for business cloud systems.
I believe that those challenges are still far to accomplish for business applications. As mentioned before, scalability and high performance is the main challenges for business applications in the cloud. For many reasons, the existing technologies may give a good solution for non-business application. But, for business we still need new and innovative technologies. The main problem of business applications is the data. Business data are different than non-business data. In addition, business application perform non-trivial data manipulation frequently.
I would say that we should move our focus on handling data and big data in the cloud rather than improving the scalability. If we success to deal with big data, we will be able to improve the scalability of business cloud. Ad the end, I would suggest that we should consider and define a new computation phase to be "data computing". Data computing should deal with all the issues in big data, data analytic, etc.
