Cloud Computing is a new name for an old concept. The delivery of computing services from a remote location. Cloud Computing is Internet-based computing, where shared resources, software, and information are provided to computers and other devices on demand.
These are major issues in Cloud Computing:
The user data can be accessed by the host company with or without permission. The service provider may access the data that is on the cloud at any point in time. They could accidentally or deliberately alter or even delete information.
There are many regulations in places related data and hosting. To comply with regulations (Federal Information Security Management Act, Health Insurance Portability and Accountability Act, etc.) user may have to adopt deployment modes that are expensive.
Cloud-based services involve third-party for storage and security.Can one assume that a cloud-based company will protect and secure one’s data if one is using their services at a very low or for free? They may share user’s information with others.Security presents a real threat to cloud.
This issue refers to minimizing the effect of cloud computing on environment. Citing the server’s effects on the environmental effects of cloud computing, in areas where climate favors natural cooling and renewable electricity is readily available, the countries with favorable conditions, such as Finland, Sweden, and Switzerland are trying to attract cloud computing data centers. But other than nature’s favors, would these countries have enough technical infrastructure to sustain the high-end clouds?
While providing cloud services, it should be ascertained that the client is not purchasing the services of cloud computing for nefarious purpose. In 2009, a banking Trojan illegally used the popular Amazon service as a command and control channel that issued software updates and malicious instruction to PCs that were infected by the malware.
So the hosting companies and the servers should have proper measures to address these issues.
