Is it a good idea to rent a VPS server?

A virtual private server emulates the operation of a separate physical server. One machine can run many virtual servers. Apart from some obvious limitations, each virtual server provides full and independent control and management, just like a regular dedicated server provides.

Each virtual server has its own processes, resources, configuration and separate administration. Usually, freely distributed versions of UNIX and GNU/Linux operating systems are used as a virtual server. For emulation, virtual machine technologies are usually used.

The administrator who owns the virtual server can install any applications, work with files, and perform any other tasks that are possible on a separate machine. Renting a virtual server is a popular type of hosting, as it provides a reasonable balance between price and features for most website and application owners. The price can vary greatly depending on the support and administration package.

Virtual servers( unmanaged) are provided at low prices (from a few dollars per month). Creating a site on such a server may require the owner to have quite extensive knowledge of operating system administration and Internet applications. Unsupported hosting is well suited for professionals and enthusiasts.

Managed virtual servers vary widely and are suitable for those who are interested in directing all efforts to the development of the site, and not to the technical details of its content.

How to choose the VPS you need?

To understand how to rent VPS that is right for you, let's figure out what VPS hosting is and how to choose a reliable VPS provider. Please note that this is not general information, but important milestones of the analysis that should not be missed.

Determine your requirements and needs

VPS can be used for private and corporate tasks: for hosting project sites and corporate portals, for deploying a VPN, for hosting software developer test benches, for storing backups (not ideal, but quite applicable for the 3-2-1 rule), for storing files, a game server and placement of trading robots for operations on the stock market. And for all these tasks, VPS is suitable, but with a different configuration.

Comparison of VPS with shared hosting

Each VPS has its own copy of the system, with root access for Unix or Administrator for Windows, which allows compiling, installing custom software with a modified configuration.

Guaranteed minimum resources (memory, CPU time). There is a misconception that VPS provides the client with more resources, but this is not entirely true: while a site hosted on a shared hosting has access to all the resources of a physical server (but many sites have to compete for these resources), only limited resources of the physical server are available to the site on the VPS, however, in some cases (most often, for a fee) they can be guaranteed, and in this case there is no competition. This results in more predictable resource usage and increases the stability of the VPS.

Possibility of archival copying of VPS with a snapshot of the entire system.

The use of iSCSI technology allows for very high performance, and also makes it possible to quickly and conveniently back up data.
