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”.
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:
Can be accessed by all its users so may be less secure because of its openness e.g. email.
System and services to be shared and accessible within an organization. It offers increased security because of its private nature.
The community cloud allows systems and services to be accessible by the group of organizations.
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.
