Cloud Computing

Cloud computing, in simple terms, is the managing and processing of data over the internet using a network of remote servers and is not hosted on a local server or on personal computer.

Basically, programs that are needed to run a certain application are now more popularly located on a remote machine, owned by another company. This is done in order not to lose on the quality performance due to processing power of your own computer, to save money on IT support, and yet remain advantageous on the market. These computers that run the applications, store the data, and use server based technology, are basically what we call “the cloud”.

Some application examples include Microsoft’s SkyDrive, S3 from Amazon. Online email has been offered by all the big names (such as Microsoft, Yahoo and Gmail)

Many small and medium size businesses now opt for cloud-based security to solve their security challenges.

. How is "In The Cloud" structured

The Cloud system is mainly made up of 4 categories:

  • Public
  • Private
  • Hybrid
  • Community

Public Cloud:

Can be accessed by all its users so may be less secure because of its openness e.g. email.

Private cloud:

System and services to be shared and accessible within an organization. It offers increased security because of its private nature.

Community Cloud:

The community cloud allows systems and services to be accessible by the group of organizations.

Hybrid Cloud

The Hybrid cloud is mixture of public and private cloud. However, the critical activities are performed using private cloud while the non-critical activities are performed using public cloud.
