If you are short on financials then you might want to give virtual servers a go. Virtual servers come in many different forms, the main ones being Windows virtual servers or Linux virtual servers.
VPS’s are frequently used for voice hosting. Voice server hosts spread their services all over the world- The UK, US, Canada and Australia. This makes virtual servers perfect. For a host, the cost of dedicated servers in each location is not practical. A VPS can be rented at a fraction of the cost of a dedicated server.
Virtual hosting is mostly used for web hosting. Particularly with hosting companies starting out that can’t make the jump to a dedicated server. A VPS offers the flexibility in that you can upgrade when needed and the redundancy of a RAID array. If you are hosting one or two websites, a VPS is also ideal.
Creators of social media apps also make use of virtual servers. If you spend all day on Facebook you will know exactly what I mean. Facebook applications are all the craze. You can do everything from manage a virtual cafe, to tend to virtual crops! Again virtual servers are a perfect stop gap rather than a dedicated server.
Databases make use of virtual hosting. Imagine having all your eggs in one basket. I.e. website and database on the same service- it isn’t a good thing. Databases are safer offsite, and offer further resilience.
Virtual hosting is very often used for DNS. I setup a redundant DNS system using a virtual hosting recently. Our main DNS is hosted onsite, but the secondary offsite. Should primary DNS go offline, secondary DNS kicks in. This allows for total service!
