Cloud computing, an evolving technology, has raised several challenges to various aspects of data processing and information handling.
Data security and privacy remains the greatest challenge to cloud computing. The use of encryption, security hardware and security frameworks will overcome protection and privacy problems.
This is another cloud computing challenge as applications can be quickly moved from one cloud provider to another. There must be no lock-in from vendor. It is still not made possible, however, since each cloud provider uses different common languages for their platforms.
That means the application should be able to integrate services from the other platforms on one platform. It is made possible by web services but it is very complex to develop such web services.
Data intensive cloud systems require a high network bandwidth, resulting in high costs. Low bandwidth doesn't meet cloud application's optimal processing capacity.
Cloud systems need to be reliable and robust considering that most companies are now being reliant on third-party providers.
