What is a Virtual Server?

In a virtual server environment, virtual servers share the resources of a physical server. They can have the same or different operating systems depending on the virtualisation software in use.


What is XEN virtual server hosting?

Xen virtual server hosting is a hypervisor running on a Linux platform that supports the virtualisation environment. you can check

Which is the most powerful Linux for Xen. It has a root virtual server that manages the hardware and virtual machines that act as virtual servers.


Advantages of XEN Virtual Server Hosting!

The advantage to managed service providers and others is that different operating systems can run in different virtual machines.  This gives the opportunity for managed service providers to maximise server usage, and for inhouse operations to consolidate different applications on a single hardware platform.


Backups to Secure Your Data


Each virtual server in a XEN implementation is secure from the others. Unless you are the XEN administrator you cannot see the other virtual servers and access their systems or data. Overall is a consideration.

Today, security in all Xen virtual server hosting environments is a shared responsibility between the managed server host and the user. The user has responsibility for systems and data and user access to it. The hosting provider has responsibility for the overall security of the XEN environment.

Data security is a concern for the user, and management of the data and its backup needs to be part of an overall continuity plan.

Data can be secured to another virtual server on the same platform, to an off-site location such as an online store, or onto removable storage media like removable disks.  If it is critical data, it could be part of a database replication strategy, so that an identical copy of the database is automatically maintained on another local or remote server.

In a hosting environment, the managed service provider is responsible for the security and backup of the physical server underlying the virtual servers. There needs to be an SLA between the hosting provider and eh customer setting out exactly who is responsible for what and how and when backup copies of each hosted virtual server are taken.

The objective is for the customer to take his own backups of vital data, and for the hosting provider to take backups of the entire hosted environment. In that way, data loss and downtime can be minimised.
