Two abbreviations are used when we mention VDS Hosting. They are VDS and VPS. VDS is a Virtual Dedicated Server. VPS is a Virtual Private/Personal Server. They mean basically the same.
If you have VDS hosting, you do not pay an all-round price for the equipment. You pay only for the part which is necessary for you. You can order accurately as much memory and place on a disk as you want. The same concerns traffic. If something happens, these parameters can be changed without problems. In comparison with other types of hosting there are some advantages of VDS hosting.
There is absence of every possible limitation on the quantity of domains, FTP accounts, data base, mail-boxes, and so forth. There is absence of any possible limitations on execution time of scripts. There is absence of compulsory and occasionally harmful, excessive installation of safety. There is complete server control, manager access. You customize a server in the manner which is necessary for you. It is possible to install any software. You have safety of virtual environment. Virtual servers are completely isolated from each other. If a neighbor “falls”, this event will not affect you. The guaranteed reception of the requested system resources.
In comparison with dedicated hosting a rent price is low. You pay only for its usage. In comparison with dedicated hosting VDS hosting can compete in the price to a certain limit of resources when a dedicated server with similar resources becomes similar under the price. And now there is a question. Why is VDS hosting with 1 GB of RAM better than a similar in price, selected unmanageable (without administration services) server in offers of “budgetary” offices? Really, sometimes VDS hosting can be better.
Firstly, powerful equipment is usually used as the hosting-machine. It means RAID-files, it means minimum risks of the data loss. Secondly, in case of emergency the virtual computer is transferred on the other physical server without stopping the operation in some clicks. Thirdly, it is easier and cheaper to a client to expand accessible resources. Fourthly, it is simpler to backup virtual computers. This is simpler both for a client and for a hosting-provider. Fifthly, “Virtuozzo” technologies of virtualization are stuffing a hosting-machine with different kinds of monitoring, warnings and alerts which are difficult not to notice. This means overall stability of the system and virtual space increasing.
