HI,

Followings are some key advantages that VPS offers over shared hosting.

# Growth Path - VPS system allows us to manage your VPS as an image. This means that your entire environment can be restored from backup to any physical server with no changes to your configuration.
# Flexibility - Some applications require that certain ports and/or protocols be opened or closed in the firewall. With Shared hosting, custom firewall configurations are not advisable for security reasons.
# Customer Installed Applications - With VPS you have your own partition and root access. You have the ability to install applications that you want. Please note that hosting company provide support for customer installed applications.
# Protected Mail Service - Each VPS account has its own private mail server, filtered by Postini. This eliminates the risk that your mail service will be blacklisted due to abuses of others sharing the same mail service.
# Performance - All resources can be regulated in the VPS environment. One customer can not run away with a large share of the resources.
# Security - VPS accounts are insulated from each other, minimizing the risk of unauthorized access from hackers as well as other customers.
