Cloud computing is gaining popularity day by day. Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network, most commonly the internet.
Typically such services are delivered by a cloud service provider. The name "cloud" computing comes from the cloud shaped symbol that is used to describe the complicated infrastructure of cloud computing.
With this technology, any person or business can create a protected digital cloud backup of files and data, available only to people with clearance.

The current issue in relation to cloud computing today is that the topic tends to confuse people as it can often be poorly explained. The key is to explain cloud computing not in a purely technical manner but in a manner that people can relate to e.g. Cloud computing allows a business to access all their important files and applications remotely from any location.
This is one example of cloud services, a rather simplistic one at that but it certainly helps people understand a bit better. So what is the services cloud computing can offer? Let’s start with Infrastructure as a Service (IaaS).
Basically, this is where cloud computing service providers offer computers as physical or more often as virtual machines. It allows companies to outsource the equipment they use to support their operations offering a complete IT solution including all hardware and IT support.
Other services include Software as a Service (SaaS) whereby a company can install and operate application software in the cloud eliminating the need to install such application software on their own physical machines.
Another interesting cloud computing service people should know about is called Desktop as a Service (DaaS). This can also be referred to as virtual desktop or hosted virtual desktop solutions.
Basically, this is the outsourcing of a virtual desktop infrastructure (VDI) to a third party service provider. The service provider manages all the back-end responsibilities associated with data storage and backup, data security and all upgrades that need to be made.
