There are two types of computing environments, essentially:
On-premises computing is the conventional computing type in which you own and operate your own devices, or your business. All the programs you use, as well as your data files, are either on individual PCs or on an in-house local area network, on your own machines at your own premises.

For comparison, in cloud computing, the programs and data are stored remotely on the Internet (in cyberspace) in a computer network run by a third party. You connect software and simply sign on to the network and work on your files from your Mac.
Cloud services are offered by providers of cloud hosting, firms including Google, Amazon, Oracle Cloud, Rackspace, Microsoft Azure etc.
The idea of cloud computing isn’t completely new. Whether you use Gmail, Hotmail or yahoo for your emails, you ‘re using cloud services, and you’ve probably been using them for years.
What’s fairly recent is the types of services provided in a cloud environment. Which now go far beyond email to include all the IT services that would be provided by an on-site computing system, such as accounting , marketing, human resources etc.
Vorteils of cloud computing
The benefits of cloud computing over on-site computing are several:
1) You can use any device to run an application, or access your files from anywhere in the world.
2) It’s easier on cloud computing.
3) Less technical know-how is required.
4) Cloud computing is doing well.
5) An eminently elastic cloud computing. Increasing the number of programs, you use or the amount of data you store does not require a heavy investment; only the cloud-hosting advisor needs to be notified.
Given these advantages it is no wonder that cloud computing has been widely embraced rapidly over the past few years. Analysts predict that the growth rate of all cloud IT spending will soon be at least four times higher than that of all on-premise computing spending.
Nonetheless, from now until 2017, analysts expect the annual growth rate of cloud computing spending to reach 23.5 per cent cumulative. Therefore, spending on cloud services will likely account for one-sixth of all IT product expenditures, such as apps, network infrastructure tools, and basic storage, by that year.
