The story of cloud storages began in 2011 and it is obvious that it will remain on the scene for a long time. The point is, with growing demands on high-res games and videos the need of cloud storages will grow even faster today.
But firstly it is essential to understand the meaning of a cloud – as no one is able to work with a technology he has no clear notion about.
What is the cloud?
The word “cloud” was chosen to depict vast distant clusters of data that we cannot touch, but that can affect us. And no wind will carry away the cloud with your data and no storm will be able to interfere with your work with the cloud (though the power outage can). As an analogy, think of the electricity used in every household – there is no necessity to connect your house to the power plant directly, and still you can take an advantage of the electricity in the house.
What are the types of cloud computing services?
There is a wide range of computing services related with the cloud, and there are three that may be especially useful to customers:
- Infrastructure as a Service (IaaS). It is the basic level of cloud computing and here all is about physical infrastructure (servers, storage disks, facilities etc.). The organizations can take an advantage of IaaS using on-demand storage and we hosting that can be changed according to the needs of business.
- Platform as a Service (PaaS) gives users a possibility to use programming language and web server. Developers usually use it in order to create apps and software there.
- Software as a Service (SaaS) it is the upper level of the cloud service and it contains software applications. Here it is possible to get certain software for monthly or yearly fee – on the contrary with traditional approach to software when you have to pay once. The pricing here is pay-for-user so companies that use this SaaS have a possibility to add or remove users any time they need. For example, Gmail, Google Calendar and Google Docs also use SaaS.
