Cloud services are programs and platforms that are hosted and run on the servers of cloud providers. The main feature of cloud apps is that by creating an account on such a platform, a person will be able to access their own information from any gadget anywhere in the world. To do this, you need to sing up with a username and password. Using cloud services is not only convenient, but also safe. Even if something happens to your phone or computer, your data will not disappear.
The situation is similar with business. The principle of operation of cloud platforms is quite simple. Cloud storage is provided to the user in the required amount, paid upon the fact of use and eliminates the need to buy your own IT infrastructure for data storage and manage it. This provides flexibility, fast scalability and reliability. For example, storing 1C in cloud storage is much safer than on a server located under a table in the office. The server may fail, catch a virus, or even disappear. And during the period of mass sales of goods, the owner of an online store will be able to simply order more resources from a cloud provider and not worry that the site will “lie down”.
There are more than ten models for providing cloud services. Cloud operators distinguish three of the most common of them:
IaaS (Infrastructure as a Service - infrastructure as a service) - providing the customer with the lease of computing resources in the form of a virtual infrastructure.
PaaS (Platform as a Service) - the client receives a full-fledged virtual platform with various tools and services.
SaaS (Software as a Service) - the client receives at his disposal certain software products via the Internet.
