Small to medium size businesses often look to handle their IT infrastructure in the most self sufficient way. Rarely will these companies have the budget or even the need to hire a full time employee dedicated to managing their network. In the past SMEs would turn to the outsourcing industry to extend their in-house capabilities and get a properly managed IT system setup with 24 hour support.
The trend has now shifted for businesses around world to get their IT infrastructure requirements fulfilled using cloud computing services. Rather than having to shift their IT processes to an outsource the SME’s can now automate the processes with cloud services.
Cloud computing is a subscription-based service offering on-demand network access to IT resources over the internet that are hosted and maintained by the supplier. This gives businesses virtual access to scalable amounts of applications, storage space and data that is completely independent of location and device.

This method makes creating apps for mobile or web use quicker and easier since the underlying infrastructure is being managed by a third party. This is usually billed as a pay as you go service.
