- Virtuozzo creates multiple isolated Virtual Private Servers (VPSs) 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.
What is (VPS) Virtual Private Server Hosting?
- VPS performs and executes exactly like an isolated stand-alone server
- Quality of Service to provide dedicated SLAs for each VPS
- Virtual Private Servers (VPS) is not a Virtual Machine (VM).
- Dynamic Real-time Partitioning - Partition a physical server into separate VPSs, each with full dedicated server functionality
- Resource Management - Assign and control VPS resource parameters and re-allocate resources in real-time
- Virtualization - Move VPSs and its application(s) between physical servers transparently with near-zero downtime
- Mass Management - Manage VPS(s) as easily as a single server in unified way
VPS performs and executes exactly like an isolated stand-alone server
- Each VPS has its own processes, users, files and provides full root access.
- Each VPS can have its own IP addresses, port numbers, tables, filtering and routing rules.
- Each VPS can have its own system configuration files and can house an application.
- Each VPS can have its own versions of system libraries or modify existing ones.
- For Example: Multiple distributions of Linux can reside on the same physical server.
Quality of Service to provide dedicated SLAs for each VPS
- Standard: Includes CPU, disk space and network I/O 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 (VPS) is not a Virtual Machine (VM).
- Runs only the same OS as root OS - Linux on Linux, etc.
- 10-100 times better efficiency, dynamic QoS changes for LB and more
Due to Virtuozzo’s fair-sharing technology, each partition can have almost the same power as the full server. Each partitio has full dedicated-server functionality – root access, rebootable, ability to install any application, change any file.
Resource Management
Mainframe-like level of resource utilization, monitoring and control on standard, inexpensive hardware. In addition to standard CPU, disk space and network I/O, it also manages memory (user, kernel and disk cache) and disk I/O. VPSs are fully isolated with minimum and maximum resource guarantees.
Drag and drop a live site or hundreds of running applications to another physical server for planned system maintenance or hardware upgrades with only a few seconds of planned downtime. Dramatically improves availability.
Create your own application and OS templates. Group them together and mass deploy the updates and applications to specific systems. Integrated sophisticated versioning database for all system files, libraries, and applications. Allows upgrade exceptions on a per system basis. Improve system uptime. Improve security. Reduce IT costs.

This is a company that delivers on all their promises. They are also very pleasant and knowledgable folks to deal with.
