Virtual Private Server FAQ:
What is Virtual Private Server?
A Virtual Private Server is a sort of a combination of a shared hosting and dedicated server. With a VPS certain system resources such as the memory and CPU are still shared with other users of the server but the file system is set up in such a way that it acts like a dedicated server. The memory, resoucres and CPU power are usually set up in such a way that each user of the server can use only a certain percentage of them, which means you have your own resources available to you. Since the system is set up so that a person can only use a percentage, your sites will work more reliable because they will always have a fixed amount of resources.
What is Virtual Dedicated Server?
Some web hosting providers prefer to call Virtual Dedicated Server to a Virtual Private Server. In either case they are actually referring to the same thing.
When do you need a Virtual Private Server?
If you have a web site which requires high resources and shared hosting is not enough anymore, you can switch to a virtual private server. The price of VPS is between shared hosting and dedicated server. Your web site will be more consistent with a virtual private server than it would be with a shared hosting because a certain percentage of each resource will be allocated to you and it is much cheaper than a dedicated server. A virtual private server is also more secure than a shared system.
Is VPS really more secure than a Shared Hosting?
Yes a VPS is more secure than a server which is shared because of the its file system. Although you are actually sharing memory, CPU and network, you do not share the file system. What this means is that if someone else's virtual server is accessed by someone else, it is impossible for them to break into your virtual file system. There is only one file system in a shared system so if anyone were to break into a shared system he/she would have access to all of the sites hosted on that server.
Why is a VPS cheaper than a Dedicated Server?
The main reason for the difference in price is that there are usually 8 or more customers sharing the resources in a virtual private server, therefore, hardware expense of a dedicated server is covered by several people. As a result, a VPS is a great way to get the privacy and security of a dedicated server at a lower cost.
Before I sign up, what should I ask to a Virtual Private Server provider?
- Is CPU, memory and bandwidth usage limited per user?
- What kind of control panel supplied for administering the VPS?
- How many users are allowed per system?
- Will it affect me if someone else's site crashes ?
- Do you provide back up of the system periodically?
Is it necessary to have a control panel to administer VPS?
Yes, it's a good idea to have a control panel to administer your virtual private server. This management of the server is both safer and easier in this way.
