There are many benefits to using Virtual Private Servers.
Each VPS account provides the user of the VPS with a full root enviroment. None of that chroot and jailshell stuff. This allows you to have your own personal configuration and version for all the services, such as http, ftp, bind, etc etc. You can install your own applications.
Each VPS has it’s own IP and Ports. When you get a Dedicated IP with shared hosting you are still limited to the ports that the shared server allows you. With a VPS you have the use of all available network ports.
VPS allows for portability. If a dedicated machine goes offline hopefully you have a failover machine. Replication of the dedicated to the backup can be a pain, Especially with MySQL (hopefully the next few versions of MySQL will solve this issue). If a VPS node (the machine running all the VPS systems) goes offline and you have your VPS running from a backend filesystem you can instantly load your VPS on another node, This can even be set up to do this automagically.
VPS provides better server security. One time I would have had to have multiple chroot (jailshell) environments to run multiple services (httpd, mail, dns, ftp, etc) instances securely and effectively (should always have bind(dns) in a chroot in my opinion). With VPS I can now run a few instances of the services in multiple tiny VPS systems and not worry about someone hacking one service and taking down another as they are completely separate virtual machines.
This also improves the over all efficiency of the physical server. I won’t get into the technical details of this unless you want me too. I could go on and on about the positives of VPS’s related to security, control, and performance.
To summarize,
- VPS is the leading technology today for providing greener solutions to the IT industry.
- VPS allows you to have a virtual dedicated server on a large dedicated server. Your VPS is private and separate from the other VPS’s on the server.
- VPS is scalable, We can add ram and harddrive space to your VPS as you need it.
- VPS is a cost effective solution to having a dedicated server.
- VPS when set up properly has greater uptime than most dedicated server. One way to achieve this uptime is every physical server that hosts the VPS machines has at least two arrays of harddrives. The extra harddrive array is used to store backups of the Virtual Private Servers that are on other physical machines. This ensure that if one server starts having issues, either through hardware or host o/s corruption, we can load the VPS’s from that server onto another server. In addition to this we have a storage server cluster that stores backups of all VPS’s. Any VPS can load directly off the storage cluster if required. This offers unparalled redundancy capabilities.
