					   A Xen VPS can help keep your system
   secure by providing you with a separate
        protected area that serves as an
 independent server. Each Xen serves as a
    secure and private physical server that
     offers protection and flexibility without
          compromising performance.




Linux Hosting
  A Xen VPS consists of several features that help it function properly
 Linux Hosting These include: Operating System Level
Virtualizaton Each server works as an independent system but it
comes with a virtualization layer hidden in the kernel of the OS This
layer plays a significant role in securing the VPS It is characterized
by the following: 1 Virtualization layers keeps the system more
protected from unwanted software from vendors 2
 Virtualization layers allow users to change system and file
configurations and to install additional software 3 Virtualization
layers help isolate Xen VPS accounts from each other Network
Virtualization A network virtualization layer helps to isolate Xen VPS
accounts not just from each other but also from the physical network
It provides each account with an individual and unique IP address
This also serves to keep traffic individually isolated to avoid
networked Xen VPS accounts from accessing one another's
activities
 A network virtualization layer also makes it possible to use software
firewalls inside a Xen VPS, as well as supports routing table
manipulations and advanced routing features Resource
Management Each server account requires resource management
features, which will control the amount of resources that each VPS
account can have This then monitors the usage of resources to
ensure that all VPS accounts run smoothly This feature is especially
important in networked systems as the various accounts in the
network share the same resources and thus require a central
monitoring and management system Aside from managing the
sharing of available resources in the entire system, the Resource
Management feature also helps protect the entire system from
Denial of Service attacks and monitor overall system usage These
resources refer to disk space, CPU power, network access, RAM,
shared memory, and number of processes; all these should be
controlled and limited for every account
  Template Package Each VPS should come pre-configured with
core services such as web service, e-mail service, File Transfer
Protocol (FTP), and shell access tools (Telnet, Secure Shell SSH),
etc These core services are customizable to meet the individual
needs of customers Some VPS hosts also provide additional
services if clients request for them Copy-on-write The VPS
system uses a copy-on-write file system that allows users to update
and customize their accounts while central files are maintained
securely This is a flexible file system format that XEN VPS benefits
greatly from RPM A Linux VPS system should also support RPM,
which is an open packaging system designed specifically for Linux
 The package keeps a copy of installed packages including all their
files By doing so, users can easily maintain, customize, and upgrade
their accounts without the risk of losing any installations and
important system files Alternative features There are alternative
features in a Xen VPS system, such as file system isolation, memory
limit, disk quota, CPU quota, and partition check pointing, among
others XenVPS - Leading provider of unique and cost effective Xen
