The hardware and expense of a VPS is shared by multiple customers, who each enjoy full root access with guaranteed resources and complete privacy. Multiple instances of the same service can be supported on a single server with complete isolation between each Private Server.  





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.
