The term Cloud is relatively new and now Cloud technology is rapidly gaining market share. The principle of the Cloud is quite simple. All data, programs and sometimes the entire infrastructure is located not locally on the user's computer, but remotely on the server. It's incredibly convenient that we are actually able to access our workplace from any computer that has network access.
Here’s an example of its principle of operation. You need somewhere to store books, but you have absolutely no room for a new bookshelf, not to mention the money to pay for it. So you go to the library and rent yourself an individual shelf for putting your books on. Later on, whatever library you enter, you see your shelf and are able to enjoy your books. It’s similar to email, we just need to go to the site and no matter where we are, in Thailand, the US or even in Zimbabwe, we just need Internet access to read our mail. Of course, the use of cloud technology is not limited to mail servers.
Cloud technology can be divided into three categories:
SaaS, PaaS and IaaS – Software, Platform or Infrastructure as a Service. The user gets the ability to access software applications, development tools, or even integrated infrastructure solutions. And all this can be used for work, collection, storage and analysis of data in the Cloud.
Advantages: access to resources from anywhere in the world, rent instead of having to buy a complete set of software, a business continuity provider.
Disadvantages: low level of security - only access via the Internet, the possible dependence on the provider, transfer of personal data storage outsourced.
Cloud technologies are used everywhere,all the pictures in your smartphone have long ago been synchronized with your account and are stored where? That's right, in the Cloud. If you lose or break your phone, the great photos and all other data will remain in the Cloud and won’t go anywhere. Clouds are used by private users, small businesses and even large corporations. Examples of cloud solutions are already on everyone's lips: Yandex.Disc, Google.Drive, Dropbox and others.
Cost savings, flexibility, mobility, ergonomics and reliability are the factors that ensure a high popularity of cloud technologies on the market today.
