you will need to read and learn a little, it's very simple to open google and search "vps" or "virtual private server" to collect info of what it is.

and you can give a look to websites of Virtuozzo, and the control panels: Plesk, Cpanel, Webmin, DirectAdmin, etc, and collect the info about the main differences between these control panel options.

for example:

What is VPS?

Virtual Private Servers are the most advanced step in server virtualization technology. They are used to partition a single physical server into many isolated virtual private servers. Each virtual private server looks and behaves exactly like a real networked server system, complete with its own set of init scripts, users, processes, filesystems, etc. .

The Basics

VPS behaves exactly like an isolated stand-alone server

* Appears to have its own processes, users, files and provides full root access
* Each has its own IP addresses, port numbers, tables, filtering and routing rules
* Each can have its own configuration files for the system and app software
* Each can have its own versions of system libraries or modify existing ones
* Each can delete, add, modify any file, including files in /root, and install its own application software or custom configure/modify root application software

As you can see from the graphic above each VPS is isolated from the others, each can have different applications and the root user of each VPS is in full control, just like a dedicated server.

As you can see from the graphic above each VPS is isolated from the others, each can have different applications and the root user of each VPS is in full control, just like a dedicated server.

Our servers have a large amount of resources available, but this would be a waste if an individual VPS was allowed to use all of them, this would leave the other VPS's without access to CPU and RAM. Virtuozzo allows us to avoid this by specifying a minimum and maximum level for over 20 critical resources.

This resource management allows us to define a minimum guaranteed level of RAM and CPU for every VPS. So no matter what another VPS does your VPS is always guaranteed to be unaffected and function normally. This also allows us to let you burst to the maximum resource level if it is available, just imagine 6+Ghz of CPU power!

Quality of Service to provide dedicated SLAs for each VPS

* Standard: Includes CPU, disk space and network guarantees
* Unique: Guarantees on memory - user and kernel, physical and virtual
* Unique: Guarantees on disk I/O and many other critical resources (over 20).

Virtual Private Servers fill the gap between shared hosting and a dedicated server, it's a bit like 'broadband' hosting, all the benefits of a dedicated server without the worry.

VPS has five main benefits over a dedicated server:

* Cost:
A virtual private server gives you the functionality of a dedicated server at a fraction of the cost.

* Data Integrity:
With a virtual private server you get built in incremental backups on top of a world class RAID 5 array to ensure data integrity.

* Management:
The nature of a virtual private server means we can manage all aspects of software upgrading and patching, no need to worry about updating your packages it is all controlled by us.

* Functionality:
A virtual private server is functionally equal to a dedicated server.

* Resource Efficient:
You get the resources you need when you need them and all resource guarantees are instantly scalable to suit your needs as you grow.

VPS has four main benefits over shared hosting:

* Control:
A virtual private server gives you root access to the system, this allows you to modify server configuration files, install applications or modify system software, in a shared environment you have to rely on server settings that are 'best fit' for all clients and this may not suit your needs.

* Security:
With a virtual private server your file system is not accessible or viewable by any other VPS owner, unlike a shared envoronment where anyone with shell access can browse through your files a VPS ensures full privacy and security.

* Isolation:
In a shared hosting environment you are 'held hostage' to the actions of others, if another shared account runs a script that crashes the server then your site goes down too. With a virtual private server you have complete resource isolation, no matter what another VPS user does it will not affect your server.

* Performance:
In a shared environment resources goes to the site 'that shouts the loudest' in other words a big site can drain all resources and leave yours performing badly. In a virtual private server environment you are guaranteed a set of resources to ensure your site always performs at full speed, these resource guarantees ensure other virtual private servers have no affect on the performance of your site

All of the above are also valid reasons to move to a dedicated server. However running a dedicated server can be time consuming and technically difficult, it also assumes you need the full power of a dedicated server and this is what makes virtual private servers so good, all the benefits, at a resource level you need and at a fraction of the cost

QUOTE

for example which versions of softs are installed there?
Virtuozzo is an Operating System Virtualization solution so a different naming convention was used to differentiate between Virtuozzo and the virtual environments of hardware virtualization. A VPS is just another term for a virtual environment or virtual server.

Virtuozzo 2.6.2
Features and Benefits

Isolated Partitions
Applications do not conflict and users can only see authorized data.

Resource Management
Manage the resources of 30+ parameters. Change parameters in real-time without affecting applications or servers. Flexible resource management allows resource minimums and maximums, and the ability to use unclaimed resources on the server.

Management Tools
Effectively manage many virtual private servers and servers with a single interface across platforms. Automate and simplify many administrative tasks.

Migration
Move between Virtuozzo servers with near-zero downtime. No SAN required.

Templates and Configurations
Provision in minutes, pre-determined server configurations.

Real-Time Monitoring and Alerts
Real-time server performance metrics and alerts enable effective management of servers and applications.

Cloning
Copy a virtual private server with new network parameters and produce a usable copy of the original virtual private server for testing and many other uses.

Backup & Restore
Online backup and restore capability to ensure data protection and availability.

QUOTE

also what r the differences between plesk, webmin and cpanel servers?

I think this link will help you to find out what is the difference between cPanel, Plesk and Webmin:
http://help.hostony.com
Virtuozzo creates isolated, secure virtual private servers (VPSs) or virtual environments on a single physical server enabling better server utilization, ensuring guaranteed resources and preventing applications from conflicting. Each VPS performs and executes exactly like a stand-alone server; VPSs can be rebooted independently and have users, IP addresses, processes, system libraries and configuration files.
Virtual Dedicated Server Technology unlike other shared hosting technologies, provides each Web site with its own, private, isolated space. VDS isolates memory, disk, CPU and network space, guaranteeing your resources from other VDSs or customers. The result is greater reliability and performance and lower costs.

Fundamentally Virtual Dedicated Servers enable each website to operate independently from other websites on the same physical machine. Virtual Dedicated Servers have their own server software that runs inside an isolated file directory and provides autonomy for each website. Security within a VDS environment is unparalleled to that of the virtual hosting environment - any compromise to a VDS only affects that individual VDS. VDS guarantees machine resources that no other customers can use or affect.

Additionally, VDS website owners have full administrative control of their environment and may install additional applications and create classic "Virtual Hosting" accounts contained by your VDS.
Virtual Dedicated Server - the power and control of a dedicated server along with the cost savings of a shared server solution.

QUOTE

is there any automatic backups?
Yes, you can configure automatic backups.
QUOTE

what about the differences between vps and dedicated servers?
is it only about resources

Dedicated Server: In the Web hosting business, a dedicated server refers to the rental and exclusive use of a computer that includes a Web server, related software, and connection to the Internet, housed in the Web hosting company's premises. A dedicated server is usually needed for a Web site (or set of related company sites) that may develop a considerable amount of traffic. The server can usually be configured and operated remotely from the client company. The use of a dedicated server saves the client router, Internet connection, security system, and network administration costs.

Virtual private servers have also become popular for their ability to establish sandboxes. For example, a single physical server might have two virtual private servers running: one hosting the production-level (live) website, and a second which houses a copy of it. When updates to crucial parts of software need to be made, they can be tested in the second VPS, allowing for detailed testing to be conducted without requiring several physical servers.

Virtual private servers are also sometimes employed to provide honeypots, allowing a machine to deliberately run software with known security flaws. Because it is possible to quickly deploy multiple virtual private servers on a single computer, honeypots are much easier to deploy, allowing better insight into the world of computer security.
Most applications can be installed within a Virtual Private Server without any problems.

You can install the software version you want, because is "like" YOUR server (you have root, and you are not sharing the vps with other users.)

(I suppose by default it will come with the latest stables, but i meant you can upgrade what you want smile.gif)

I agree with mblendinger.

Yes, there wil be installed the latest stable versions of PHP, Mysql, Apache and etc.
