Cloud Computing is an Internet based solution that enables users to easily connect with virtual servers, access any data stored and open applications wirelessly, via their desktops, laptops, servers or mobile devices.
There are four main types of cloud's being utilised at the moment these include:
Public cloud
Public cloud services are extremely popular and are utilised by a multitude of users worldwide. Some popular examples of public cloud's include Google Compute Engine, Amazon EC2 and Microsoft Azure. Public cloud's are highly favourable due to the fact that they offer universal access, are extremely economical and allow for flexibility.
Private cloud
Private cloud services are utilised by businesses on a global scale. This is due to the fact that it allows organisations to host servers, develop networks and store data internally and privately. Private cloud's are easily customisable to meet the needs of an organisation and are highly secure as they operate on a private network, which is managed by the organisation. Additionally, the fact that a private cloud operates on an organisations private network, and is maintained and managed by employees of the organisation, allows for greater control on security and data privacy as public users will not have any access to a private cloud.
Hybrid and Community Cloud
Hybrid cloud services offer a combination of both public and private cloud services. Hybrid cloud's allow organisations to utilise public cloud services whilst continuously storing the company’s data privately and securely on a private cloud. Whereas community cloud's allow organisations who share similar privacy and security practices, to access cloud services simultaneously.
