How It Works:

Each VPS behaves exactly like an isolated stand-alone server:

• Each will 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 could have its own configuration files for the system and application software.
• Each could have its own versions of system libraries or modify existing ones.
• Each could delete, add, modify any file, including files in /root, and install its own application software or custom configure/modify root application software.

VPS's offer Quality of Service guarantees standard shared hosting can not:

• Resource Guarantees: Includes CPU, disk space and network guarantees.
• Guarantees on memory - user and kernel, physical and virtual .
• Guarantees on disk I/O and many other critical resources.
• Performance Isolation - heavy traffic and CPU load on one Private Server will not have a negative effect on the other Private Servers.
• Functional Isolation - each Private Server has its own set of applications and services.
• Fault Isolation - errors created on Private Server will not affect other Private Servers. For example, a bad CGI script can crash a server, but only the Private Server with the script will be affected.
• Address Isolation - each Private Server has its own set of IP addresses.
