Virtual hosting vs VPS server. All the pros and cons.
Let’s compare virtual hosting with virtual dedicated server. Consider all the disadvantages of virtual hosting and the advantages of a virtual dedicated server.
VDS and VPS – Virtual Dedicated Server (virtual dedicated server) and Virtual Private Server (virtual private server), respectively. Despite the fact that VPS is virtualization at the operating system level, and VDS is virtualization at the hardware level, in fact, the final product is the same.
In both cases, separate, protected private containers are started on the same physical server, in which you can install the operating system
(depending on the type of virtualization) and deploy your project. Further in the article we will use exactly the abbreviation VDS, since it is more suitable for the final product.
Such a virtual server functions in the same way as a physical one. You have the ability to customize the system as required by the technical task of the project. Collect one, two, or even three different versions of php. Create the required number of FTP accounts, change the settings of services and services. Virtual dedicated server does not overlap with the “neighbors”. “Breaking down” of one of the VDS servers will not entail stopping all the others. On the same physical server can be one or more containers. The number of containers is limited by the resources of the physical server and the greed of the owner of the physical server.
VDS has dedicated IP and guaranteed resources. As part of OpenVZ virtualization, the client can change server resources without rebooting the VDS itself. The maximum performance of the VDS server may be greater than stated by the owner of the virtual server. Operating systems limited: Fedora, Centos, ubuntu, Debian
The advantages include:
- Dedicated IP,
- Guaranteed resources
- The ability to increase server resources without rebooting,
- Requires GNU / Linux administration experience.
Minus overlaps a huge number of control panels, which reduces the need for server administration to a minimum.
Virtual hosting with resources is a little worse and better at the same time.
By unique advantages can be attributed to the cost. On average, virtual hosting can be purchased for 80 rubles when paid for a month.
- lack of guaranteed resources
- shared IP
- the inability to change configuration files,
- the inability to install additional software.
We will understand the points.
Lack of guaranteed resources
All users use all resources. This means that at certain points in time, the system will be able to allocate 2GB of RAM specifically to your process, and 512 megabytes will not be able to at another. From this depends on the resiliency of your site and its visibility in search engines.
On a virtual hosting on one IP there can be more than one hundred sites. This affects both SSL setup and site optimization. In addition, it is possible to get a non-working site due to a neighbor who was blocked by ROSCOMNADZOR. Or get problems with sending mail, when the IP of the shared hosting mail server gets in the so-called “black lists” (BlackList). Of course, you can buy additional IP, but the total IP is a definite minus of virtual hosting.
Lack of ability to change configuration files
The user is not able to edit configuration files, for example, mysql or any other configuration files. These files are configured once by hosting administrators for all clients.
The inability to install additional software
The user can not put additional software on the hosting, since such an installation will affect all users of the virtual hosting. Only the administrator has this option.Tags: virtual server hosting, vps web hosting
