If you are looking for an adequate alternative to a regular server, then in modern conditions it is a virtual server. It has all the advantages of a real server, and its rental price is more affordable and flexible. The user receives a full set of necessary programs and the entire gamut of settings. The possibilities are the same as on the physical server. But the level of security and power is higher. You can find a good VPS server here https://justvps.com/.
The user has a wide selection of configurations for realizing any goals, a list of templates for virtual devices that help reduce startup time, and reliable provision of computing resources. Virtual machine information is not stored on conventional server drives, but in a centralized data storage device. If the client needs more resources, he just need to change the server parameters, and immediately he gets additional RAM, strengthening computing capabilities and increasing the capacity of the hard drive.
To host websites on the Internet, a physical medium is required – a high-power computer that has a permanent connection to the Network and a wide communication channel. A home computer is not suitable for this, its capabilities are limited by the local provider. The problem is solved using virtual hosting – renting a physical medium from a company specializing in the provision of such services. The most promising and flexible method of hosting websites is VPS hosting using virtual machines.
Virtualization
It is unrealistic to provide a separate computer for each client of the provider, so the hoster uses the principle of virtualization. Using special software, several virtual machines are created on one physical computer. At the same time, there is no difference for the user whether the computer is running – real or virtual.
There are two types of virtualization:
- hardware
- program.
Hardware Virtualization is done through dedicated server processors. Each virtual machine uses a specific part of the processor core. Thus, all virtual machines are isolated, and overloading one resource does not affect the operation of other systems. Guest operating systems can be of any type, this increases flexibility in the choice of methods for solving assigned tasks.
When implementing software virtualization, each virtual machine starts within the framework of an already installed operating system. High resource consumption by one virtual machine slows down the work of other guest systems. Today, the use of hardware virtualization prevails.
Shared hosting
Placing a website on the provider’s server (host) is called hosting. Each site uses shared server resources within the framework of the installed software and the selected tariff plan. Such an implementation is suitable at first, at the beginning of the existence of the site. While there are few visitors to the site, its speed is not a determining factor. With the development of the site and an increase in the number of users, the performance of a shared server may not be sufficient. The growth of traffic and the load on the site can compensate for the virtual VPS server.
VPS hosting
A virtual server allows the site owner to install their software to implement the capabilities of the resource. Working with VPS (Virtual Private Server) does not differ from working on a personal computer and does not depend on other sites hosted. Compared to shared hosting on VPS, you can host an unlimited number of websites and databases. However, for the convenience you need to pay and using a VPS server is much more expensive than shared hosting.
