The Cloud Computing concept is one based on the outsourcing of computing resources. Rather than purchasing certain hardware or software at relatively high capital expenditure, companies instead rent applications from service providers and access them over the Internet. An alternative to managing traditional IT resources - a host company takes care of the background technicalities and you simply connect to your services through a secure Web-browser, using them whenever needed. These services are hosted online on secure servers - a network of computers collectively referred to as the Cloud.
Advantages of Cloud Computing
Lower Cost and Initial Investment
Cloud computing is much less expensive than getting similar services in the traditional way. Companies will be paying solely for the aspects of the service that they demand, which will in turn affect the price.
A cloud service is much easier to scale up or down than the traditional computing service. This is the perfect option for companies that require flexibility.
Companies in today's world are trying to survive in a very competitive and intense business environment. Many of them are forced to scale down. Several other companies manage to make it through, which calls for staff expansion.
The fact that no hardware is connected to the availability and the provision of cloud computing services makes them easier to manage.
A company's IT experts will be free of worries connected to available storage space or the manner in which servers get administered. All concerns will be focused on performance.
In addition, a company's IT experts can rest assured that all updates take place without their involvement. Maintenance and upgrades will be entirely dependent on the cloud service provider.
Taking It Anywhere
Cloud services are 100 percent location independent. This can be a huge advantage for companies that relocate frequently or for business representatives that have to do a lot of business travel.
Cloud services can be accessed from any location that has internet access. This means that important projects and company operations will be available anywhere, anytime. Accessibility from any location permits work from home and business travel without too many preparations.
