It’s a type of web hosting when all the resources of an entire computer (server) are given to one client.
Dedicated hosting differs advantageously from shared hosting and VPS by not limiting the resources of a physical server allocated to one user. It also doesn’t limit access to the server which allows a user to install any software they wish and even operational systems.
Despite the high quality hosting dedicated servers provide, they are usually less popular than shared web hosting because they are more expensive and more difficult to administer. However, dedicated servers are widely used in a corporate environment.
Advantages of a dedicated server
If compared to shared hosting, a dedicated server is, as a rule, more productive, reliable and is only limited by the physical resources of a computer. Dedicated hosting offers far more opportunities for its users:
- SSH access to the server, which allows for remote server administration. It also means that a user can remove or install programs and files at one’s own choosing
- Possibility to reboot the server remotely, which is often needed in cases of hardware or software failures
- High security level. Users of shared hosting divide disc space and other server resources among each others. That is why if one website gets hacked, other clients with their resources located on one physical server may suffer as well. A dedicated server, meanwhile, doesn’t have this problem. Therefore, it is more reliable and secure.
- Higher channel throughput rates. Though quite often hosting providers offer shared hosting with allegedly unlimited traffic, in reality a client will be enjoying much less traffic than on a dedicated server. It can be explained by the fact that physically servers are connected to network channels with 10, 100 and sometimes 1000 Mb/s bandwidth throughput. So if hundreds of clients are using one and the same server, real bandwidth throughput per each user is going to be significantly lower than on a dedicated server.
- High productivity rates. Very often on a shared server there may appear such a situation when one or several user accounts start consuming most of the server resources, which leads to a significant decrease in productivity for other users and even to denied access to their websites. This problem can partly be solved by relocation to a VPS (Virtual Private Server) which is one more type of shared hosting but with strictly limited resources per user. Nevertheless, even the best virtualization technologies can’t provide reliability and productivity of a dedicated server.
Disadvantages of a dedicated server
In spite of all the advantages mentioned above a dedicated server is going to cost more than shared hosting. For instance, while prices for high-quality shared hosting range from $15, a dedicated server is going to cost you at least $70 and more depending on the price of computer components and internet traffic.
Rookie users may say that a dedicated server is hard to administer and exploit as it demands certain expertise in the structure of the server OS and software. Shared hosting, in its turn, doesn’t have this problem because a physical server in this case is administered by an experienced employee of a hosting company. Many hosting providers offer administering services for dedicated servers as well but they charge a lot for it.
