VPS hosting works under the principle of virtual private servers. Each user is given separate resources using a single physical server. The users in a way share the server and work using the resources dedicated to them. The illusion of multiple servers is created by the partitioning of a single server. The customers can access the resources of the host and can act isolated from the whole network. They have total security in the virtual private environment.

Plesk VPS hosting is a web hosting service introduced by SWsoft that works by implementing the VPS method. The attractive feature of Plesk is a user friendly interface designed using graphics. This interface helps the users to interact with the system even if they are not that aware of the basics of VPS system. It replaces the command prompt system that was developed for these unskilled users.

Plesk is used mainly to develop web sites and accounts. There is a provision where the administrator of the server can make a template to know the required resources well in advance. This will ease the allocation of these entities for the users and the clients. Plesk also allows the flexibility of using in both windows and Linux.

In terms of security Plesk often have to face many criticisms. The system is not that secure as the users share the same resources. They can access the files of other servers connected in the system. Accessing the root system and exploiting the resources is also possible in Plesk VPS hosting.

Plesk comes in two main versions for simplifying the over all management. The Linux and UNIX systems mainly implement the Plesk 7. It is easy to manage the web server in these systems through the Plesk software. It allows the restart of the system for enhancing the performance. The spam protection is much more efficient in Plesk7 to filter all emails supposed to contain spam.

Plesk 6.5 is the latest development from Plesk team of SWsoft. It is specially intended to work with Windows. The windows 2000 or 2003 servers are highly benefitted from the Plesk 6.5. The main purpose of this software is server administration.

The login in plesk is implemented in four levels. The administrators are allowed access through special login level. This gives him the access to manage everything in the system. The master level login helps him to manage all the virtual servers together. The administrator can give certain specific rights for the user. The clients can login and create new accounts. Domain owner gets access for administrating his domain. This is extended to include only his domain. The users have the facility to maintain passwords and other settings on their own. The access to this is provided through the mail user login.

There are many disadvantages for Plesk. This includes the insufficient data backup facility. Plesk has no feature of loading the files into FTP servers. Thus the files are saved only in the server disk. This will lead to insufficient data storage for the large files. The result is that the administrators prefer to go for backup. This results in storage insufficiency or wastage of space improperly.

Plesk has several restrictions that prevent the user from accessing several applications. Though these are negative remarks of Plesk VPS hosting, there are several positive aspects for Plesk. They include the ease of use that plesk offers the users. It is highly secure and stable. There is a huge selection of language and this option supplements the interest of users in plesk. The automation keeps the users benefitted of the latest advancements in technology.

The reduced expense and the user friendliness have always made Plesk the best of the virtual private servers hosting systems. The administration of the web sites is no longer a head ache and the management task is more simplified.
