Cloud Computing Challenges

Cloud computing, an emergent technology, has placed many challenges in different aspects of data and information handpng. Some of these are shown in the following diagram:

Security and Privacy

Security and Privacy of information is the biggest challenge to cloud computing. Security and privacy issues can be overcome by employing encryption, security hardware and security apppcations.

Portabipty

This is another challenge to cloud computing that apppcations should easily be migrated from one cloud provider to another. There must not be vendor lock-in. However, it is not yet made possible because each of the cloud provider uses different standard languages for their platforms.

Interoperabipty

It means the apppcation on one platform should be able to incorporate services from the other platforms. It is made possible via web services, but developing such web services is very complex.

Computing Performance

Data intensive apppcations on cloud requires high network bandwidth, which results in high cost. Low bandwidth does not meet the desired computing performance of cloud apppcation.
