Hosting for the site: what is it (in simple words), types, what to choose

In essence, the site - a set of files and folders. In order to store it all and provide uninterrupted access to them, you need hosting. In simple words, hosting provides storage and maintains the site. This is a productive server in a data center with uninterrupted access to power, internet, etc.

Special software is installed on the server, which allows sites to run various scripts, process code, etc. There are several types of hosting, they differ in features, performance and price:

• shared hosting;
• VPS (virtual private server);
• dedicated server.

Each of these types of hosting has its own advantages and disadvantages. Consider the features of different types of hosting.

Virtual hosting

One good server can host tens of thousands of sites. All 100% server resources are not divided evenly among these sites, and provide them as needed. For example: at some point in time the server load gives some sites, at another point in time - others. There are sites that practically do not load the server at all due to low attendance or other reasons. However, all pay the same.

In simple words, the features of virtual hosting look like this:

• all sites are located on the same IP, quality and poor quality side by side;
• The server resource - one for all customers;
• if the server stops working, all sites on it stop working
• does not require special knowledge in administration;
• suitable for the majority of undemanding to resources projects;
• The cheapest type of hosting.

Some hosts offer separate terms and conditions for different CMS. 

Virtual dedicated server (VPS)

As in virtual hosting, the VPS server space is divided into several clients. But the difference is that each client is guaranteed a certain amount of performance. For example, one client reserved for itself 2 GB of RAM and one core processor, another - 6 GB of RAM and 2 cores, etc. If someone exceeds the limit, only his VPS will stop working, all other clients will continue to work without interference.

The main features of VPS can be formulated as follows:

• each account is guaranteed resources (can be configured as desired);
• it requires knowledge in administration, because in most cases a «naked» VPS is provided;
• it is possible to install almost any software;
• Suitable for resources that are critical accessibility, or not enough virtual hosting resources (online stores, bulletin boards, large content projects);
• More expensive than virtual hosting.

Thus, VPS - this is the next level of development of the Internet project. Many people start with virtual hosting and then come to VPS and then ...

Dedicated server

Whole server on a rack in a data center - all at customer service dedicated server. You can load it with any tasks, install any software, etc. Dedicated server provides maximum freedom and performance, while maintaining round-the-clock uninterrupted access.

The main features of a dedicated server:

• the customer is given full access to the server;
• No one except the client does not affect the server;
• will have to administer yourself or hire a specialist;
• installed any OS and software;
• is suitable for any tasks, but most often is ordered for high-loaded projects;
• the most expensive type of hosting.

For the majority of Internet projects suitable virtual hosting. If virtual hosting resources will not be enough, you need to move to a VPS. Dedicated server (or even a few) - the last stage of development of the Internet project, which is not required by everyone.
