What is a cloud server and how to use it

Imagine that all your employees stopped using separate PCs and laptops, because you replaced the entire fleet of equipment with one powerful piece of hardware. And it is not just in another room, but in a separate building, where the “supercomputer” is monitored around the clock by qualified IT specialists. What a saving!

Unfortunately, you can't do this with a fleet of work machines. Even with VDI, each employee will need a laptop or thin client to connect to their workstation. But dividing the resources of physical servers and "cutting" them into virtual ones is very simple.

Cloud servers implement this concept, and modern virtualization technologies help to do this.

How cloud servers work

A cloud server is a service that allows you to rent the provider's computing resources for your tasks. The wordpress web design agency productive hardware installed in data centers is virtualized, and the client receives exactly as much power as their tasks require.




At the same time, the user can manage any parameters of the cloud server:

scale computing resources - vCPU, RAM, disk space, etc.;
change the type of data carriers used, etc.
The client does not receive access to the physical machine, but this is not required. It is serviced by qualified data center employees.

What is the difference between cloud servers and VPS/VDS

There is a misconception that VPS/VDS and cloud server are the same service, just the name is different. Despite the fact that the services are indeed similar, they are structured differently.

When organizing VPS/VDS, one physical server is divided into many virtual ones. Their configuration is fixed. A cloud server is a virtual machine deployed within an entire cluster. This allows customers to flexibly scale computing power in both directions ( both increase and decrease ). Providers offer customers of cloud servers flexible pricing methods. For example, with the Pay-as-You-Go model , you can pay only for actual power consumption.

Simply put, a cloud server is a “slice” of resources from one or more physical machines.

Advantages of Cloud Servers

Without a cloud server, solving IT problems would be much more difficult and expensive. Before the advent of virtualization technologies and services based on them ( IaaS , then PaaS and SaaS), companies had to buy, configure and maintain physical servers themselves. Of course, in some cases, this is still the case - for example, if the company's information security policies provide only for an on-premise model of infrastructure organization or the business uses special software that requires all the resources of the hardware machine at once.

However, those who are not burdened by such conditions can solve their problems using cloud servers. Why do businesses increasingly choose this service?

A few seconds from purchase to start using
Buying your own physical IT equipment is a real quest. Imagine: you need to agree on a budget, choose a supplier, buy a server and wait for it to be delivered. And then install and configure it. Often, this process can last for several months.

With a cloud server, everything is much simpler. Just select the required configuration and pay for it - you will get access to resources in just a few seconds.
