Server users are repeatedly encountered with the concept of "Deda". What it is? This term comes from the abbreviated dedicated server, which means "dedicated server". This review will tell you what it is for and where it is used.
Definition
A dedicated server is the provision of hosting services when absolutely autonomous physical equipment is leased to a client. This type of hosting is the most optimal in the case of launching applications that for one reason or another cannot be present together with other projects on the same machine. Or they may require a large number of allocated resources in order to maintain operability and be able to develop.
The difference between a dedicated server and a virtual
Dediks - what kind of server? Often this type of equipment is located on a special technical site in the data center. Its main feature is the complete transfer of all rights to configure and administer the server to the lessee. The owner gets absolute access to all the hardware and software that is on the rented equipment.
The client can choose the operating system for the Dedic server, as well as change the entire configuration. He has the right to carry out any testing or maintenance work. There is no risk of harming other services or servers. Very often, in order to be able to manage the BIOS and software remotely, the client gets access via KVM in addition to the server.
Providing uninterrupted access to the server in an uninterrupted mode is one of the significant advantages that Dedics have. What does it mean? For example, if some information is located on a machine separate from the server, then even if technical work or preventive maintenance is performed on it, access to this information will not be blocked.
Benefits over Cloud Servers
First of all, a dedicated server has a lower cost. Similar characteristics of cloud solutions will cost more. In theory, a cloud server provides an opportunity to save on the price of resources when it is idle. But in practice, he almost does not. For example, at night, backup tasks work. Such a process for a large project can take eight or more hours.
Another drawback of cloud solutions is the additional consumption of resources for many layers for network and disk subsystems, as well as for virtualization. This significantly affects the effectiveness of the equipment. This is especially noticeable on highly loaded projects.
Security is also minus cloud servers. In addition to the client itself, cloud owners also have access to data on hard drives and in RAM. This may be a threat.
Dedicated Server Applications
Often this type of equipment is the most convenient in order to realize access to computer games online, which imply not only the availability of huge computing resources and serious hardware requirements, but also the simultaneous presence of a large number of gamers entering the site from various parts the planet. In addition, all data in games must be saved.
In the absence of deleting game accounts, kickbacks when combining several game servers or during preventive and technical work, it becomes possible not only to save all game data, but also to increase the server rating among players.
Dedicated service devices in automatic information processing systems can be used not only to reduce the load on a particular computer. Dedics are also responsible for ensuring the network security of the project. What does this mean? In case of any hacker or DDOS attack, when the database is located on a separate machine, important information will not be affected. A hacker who has taken possession of the resource will not be able to inflict any significant damage on the project.
Dedic server can be called the server of any online game, which runs only the server side, and the data on the characters and players are located on another machine. Very often, if it is possible to use a version of a device with an operating system of the Unix family, the choice falls on it. It is cheaper and easier to use.
Dedicated servers are also used to host sites related to highly loaded projects.
Connection
How to connect to Dedik? The easiest way is to use a utility that is built into the Windows operating system. It is called "Remote Desktop Connection." It is located in the OS system folder as an executable file mstsc.exe.
The connection itself is intuitive. It will prompt you to enter the IP address of the remote server, the login under which the connection will be made, and the password. After clicking on the confirmation, the connection will occur.
There are also utilities that also use the Remote Desktop Protocol, but they have several advantages. This can be Dedic database storage, sorting, commenting and other functions. The most famous connection utilities are the Dedicated Server Book and RMS. They help the system administrator very well. When connecting, do not forget about security and use a VPN or proxy.
Creating a dedicated server
Many customers are interested in how to create a dedic. You need to understand that this is a physical powerful computer that is constantly connected to the network. Is it possible to create it yourself? Not. There are several options:
- If you constantly need access to the server from different places, it can be done from your own computer. To do this, take care of its constant connection to the network. And it should be powerful enough. On it you need to open port 2289, through which you can connect to the remote desktop protocol. A dedicated IP address is another condition.
- The assembly of the server can be ordered from any hosting company that will provide server rental for the configuration ordered by the client. The user will be given an IP address, as well as a login with a password. This option is more expensive, but also more reliable.
- The most expensive option is to purchase a physical server, and then install it in a data center for maintenance.
Getting a dedicated server
In order to get a Dedic, you need to contact the hosting company that provides this service and leave a request on the website or in writing. After reviewing it, you will need to indicate the desired configuration and software. After everything is done, the client receives the equipment and concludes a contract.
Some companies provide free access to Dedik for a specified period. This is a demo version so that the client can appreciate all the advantages and disadvantages of a dedicated server. At the end of the term, you can either continue to use, but already paid, or refuse the service.
Summary
As it becomes clear from the foregoing, Dedik is just a server. Its characteristic feature is the rental of equipment to the client. If you have to work on projects with a high load, then a dedicated server will be the best choice. There are special programs for its management. Dedica concern all online games.
