Sales department is a place where you can ask about hosting packages, about server and about stuff that you want to order (domains, hosting packages, dedicated ips, SSL certificates etc.).
The redundancy of your storage is also important. The majority of VPS have a RAID storage. I guess everyone knows this. I have no confidence in an environment that is not using RAID. It is not only good for data security and performance, but also beneficial for the speed to put in place following a failure of one disk.
Google calendar shows how far Google has come in its ability to deliver services "in the cloud". Once you put the privacy and security issues of someone else hosting your data aside, my biggest concern about virtual services and "cloud computing", has been the availability of data when you're not able to connect the cloud.

VPS stands of virtual private server. This plan arises because there is a need for businesses on shared hosting plans to use more resources. Usually, a shared environment is less stable because the same server hosts several hundreds sites. This means there is a competition for server resources. The more sites hosted on the server, the poorer the performance.
There are too much data to move. Just imagine that some big organisations like Google or Yahoo trying to go 'cloud'. They will need to move thousands of terabytes.
Uptime Assurance- your website would not be accessible to the users during downtime of the server. A good hosting company should be able to offer you a server uptime of 99.9% for the best results.
You can make system updates on your server as and when needed without affecting and getting affected by the others. Some web hosting companies will manage and update your server daily so that your server is safe and secure each time of the day.
Cloud hosting Obviously, having a dedicated server ensures that your site is more scalable. Of course, if your website is never intended to reach such a stage, hosting it on a dedicated server would be a waste of resources. The majority of the websites require only a shared server or a VPS server.
Customers therefore get hosting services that are similar to that of dedicated Web hosting without sacrificing performance and for a much reduced price.
