What Are Virtual Servers?

Virtual server technology is a cost effective solution that allows splitting your Linux boxes into many virtually isolated servers and saves you hardware related capital investments. H-Sphere offers a web interface for FreeVPS, free Linux based software which extends the vserver solution with a series of improvements.

>Complete Root Access

Virtual servers have their own root accounts and root directories in sub-directories of the main server, which gives:

ability to install and run its own application software
ability to manage own config files
ability to configure/modify root application software
ability to delete, add, modify any file, including files in the root server
full control over all files and processes on the virtual server

Full-Featured System Administration as of a Physical Server

Like physical servers, virtual servers have:

multiple users and groups
own user and group quota
own crontab
own chkconfig settings

Complete Independence

Virtual private servers are completely isolated from each other and from their main physical server. Each VPS has:

complete isolation of virtual server processes, even from the root server
independence from underlying hardware: virtual servers can be easily moved to another physical server

Own Network Configuration

Each VPS has its own network settings including:

own private localhost network interface
virtual ethernet devices configuration
multiple IP addresses added without downtime
IPs assigned to own virtual network adapters
own hostname
own domain name
own routing tables
ability to configure own DNS servers

Limitable Resource Consumption

Physical server resources, such as traffic, disk space, RAM, and number of running processes can be limited by master admin and purchased by the account owner. VPS also allows to limit the number of files in use.

Shared Administrative Tasks

Running on the same file system as the main server and sharing its files and directories, virtual private servers share common administrative tasks, such as:

data backups
task monitoring
network traffic monitoring for each virtual server
batch installation of RPMs on selected or all virtual servers

Master Admin Management

H-Sphere offers tools for VPS management by master admin, including:

administrative tools to start/stop/suspend/resume virtual server
ability of assign IP addresses
installation of virtual ethernet devices
tools to allow/deny new process creation
tools to term/kill signaling for all virtual server processes

Complete Integration With H-Sphere

H-Sphere provides a web interface for VPS management, including:

VPS Plan Wizard: ability to create VPS plans with different pricing and configuration
A control panel account for each virtual server with online billing and support center
Physical resource management interface to configure RAM, disk space, traffic, and server processes
VPS network configuration: assigning IPs to virtual ethernet devices, adding and changing IPs, setting VPS gateways
