Cloud computing, also termed as ‘utility computing’ has entered the spheres of business and education only to promote exchange of information. Virtual and/or physical resource pooling not only decreases the efforts of transferring data but also ensures its safe passage across users, organized storage for future use and wide range of facilities for data rederivation at minimal costs. After becoming available for public use, Cloud facilities have taken different formats.
Here are three basic Cloud computing types which are divided on the basis of their costs, facilities and security strategies, namely:
Cost Effective and Easily Available Public Cloud
The most common types of Cloud computing, a Public Cloud is hosted from a homogenized structure which is controlled and secured by the provider. On the other end, users can avail to access their respective Cloud accounts through networks following standard protocols like Internet. Because of their relatively cheap setup, public clouds are more economically affordable than other Cloud types. However, the ease of accessibility projects potential dangers of data leaks and jeopardization of information.
Individual First at Private Cloud Space
Even though they are housed in the same structure as Public Clouds, Private Clouds are comparatively more secure since they are maintained over and accessible through private networks only – irrespective of the fact that they are virtual or physical. Thus, private Clouds can only be managed by provider and individual client, thereby reducing risks on data security. Software maintenance, cyber security and protection hardware are costs covered by Cloud provider and hence the rental of private Clouds is slightly higher than public accounts.
Better Facilities from Hybrid Cloud
Hybrid Clouds are rare accounts which are often used by corporate businesses for the availability of facilities like data security and ease of access. Hybrid Clouds allow users to utilize public clouds for common day operations and access private clouds for confidential operations which demand concealment of data or security of participating bodies. So, at a slightly higher cost to private clouds, users can operate state-of-the-art computing setups.
Cloud computing has assimilated into the virtual world with such comfort that it becomes almost impossible to believe that it is barely a decade old phenomenon. Today, hosting websites, streaming content, delivering software, analyzing multi-source information etc. are possible because of the available versions of Cloud, while with its leading developments one can also foresee a future where Cloud computing would be able to make human society more smarter and safer.
