Virtual Servers

What are Virtual Private Server (VPS) services?

Parallels's Virtuozzo virtualisation software is used to partition a single physical server into many isolated virtual environments, creating the VPS service. Each virtual environment is completely isolated and behaves exactly like a real networked server, complete with its own set of init scripts, users, processes, filesystems, etc. Each virtual environment can have different applications and the root user is in full control, just like a dedicated server.

Resources:

Virtualised services have many benefits over a dedicated server:

• Cost: All of the functionality of a dedicated server at a fraction of the cost.
• Reliability: Bundled incremental backups ensure your data remains safe.
• Manageability: Tools help you add applications, change and upgrade your service instantly.
• Burstability: Get the available resources you need when you need them.
• Flexibility: Instantly increase your service plan to provide for more resources as you grow, easily move to a new more powerful server.

Virtualised services have many benefits over shared hosting:

• Control: With administrative or root access, you can modify server configuration files, install applications or modify system software.
• Security: Your file system is not accessible or viewable by any other customer, your files are ensured full privacy and security.
• Isolation: You are fully isolated from other users and actions on the server. No other customer can slow down or affect your service.
• Performance: Your resources may be guaranteed based on your plan, nothing else on the server will affect the performance of your VPS.
