Understanding Virtual Private Servers

Overview

Briefly, a Virtual Private Server (VPS) performs and executes exactly like an isolated dedicated server, providing you with the utmost control over your server space, at a fraction of the cost. More specifically, the Virtuozzo technology that Webiness employs creates multiple isolated Virtual Private Servers on a single physical server to share hardware, licenses and management effort with maximum efficiency. Each VPS performs and executes exactly like a stand-alone server for its users and applications as it can be rebooted independently and has its own root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files. Light overhead and the efficient design of Virtuozzo makes it the right virtualization choice for production servers that provide demanding web applications, real-time data display and overall system control.

Dynamic Partitioning

Due to Virtuozzo's fair-sharing technology, each partition can have almost the same power as the full server. Each VPS sits on its own partition on one server, each with full dedicated-server functionality — root access, rebootable, ability to install any application, change any file and more.

Resource Management

Mainframe-like level of resource utilization, monitoring and control on standard, inexpensive hardware. In addition to the standard CPU, disk space and network I/O, a VPS also manages memory (user, kernel and disk cache) and disk I/O. VPSs are fully isolated with minimum and maximum resource guarantees.

 

Additional Features & Benefits

• Isolation
  Virtuozzo provides isolation between each VPS and each customer. No customer can affect or crash other customers on the same server, even when customers have administrative access. Virtuozzo helps to minimize any downtime and eliminates issues and conflicts between customers.
  
• Customer Self - Management
  A web based interface allows end users to backup, restore, manage, recover, repair and reinstall a VPS without technical support.
  
• Unmatched Plesk Support
  Tight integration with Plesk includes templates that help use system resources well and expand system density for the best ROI and most efficient management of any service using virtualization.
  
• Flexible Resource Control
  Virtuozzo has the capability of limiting the resources of each VPS, but it also can be configured to allow VPSs to burst and use available resources on the server. Virtuozzo provides the flexibility and control to customize and provide a range of services to meet the requirements of any customer.
  
• Complete Control & Administration Tools
  Virtuozzo has a full set of tools for administrative level control including command line, GUI and web-based access. These intuitive tools to help you administer virtualized servers at any skill level, and manage Linux and Windows servers from the same interface.
  
• Application Templates and Support
  Include common applications in service offerings. Leverage the Virtuozzo templating technology to maintain small application footprints and overhead and provision and update quickly and easily.
  
• Migration
  Move VPSs to other physical servers to minimize the impact of server issues, upgrades or maintenance.
  
• Easy Customer Upgrades
  Upgrading an existing customer to a new Virtuozzo service is simple, changing the resources, the configuration or even moving to a new server can be done in real-time and without service interruption.
  
• Backup and Restore
  Self-administered incremental and scheduled backup capability comes as a part of the Virtuozzo feature set. End-user backups enable quickly restoring and resuming work without support intervention. Administrative backups ensure VPS, server and business continuity for your customers.
  
• Secure
  A virtualized server is more secure than a dedicated server. The underlying architecture changes access points and prevents attacks such as Denial of Service.
