The world is changing. You no longer need to have the power of a whirring supercomputer to to run specialized computing services. You could easily run a NORAD-like operation from your tablet, or even your smartphone! How is this possible? The answer is virtual servers. Virtual means that the service is running in a location apart from yourself. A server is basically a specialized computer designed with more power for storage and processing, and to run all the time.
Services that Run on Virtual Servers
Most virutal services, no matter what the front end of the interface looks like, connect to a database – a list of tables that are connected to each other. The tables store information and provide it when needed. For a smartphone encyclopedia app, you could gather information on all Smartphones, including their features and characteristics,and list all the available applications. You would then connect the applications table to the smartphone table by defining which app runs on which smartphones. Servers have the computing power to host and run your encyclopedia without fail.
How Virtual Servers are Set Up
If you inquire into buying a server for your application, you will discover it will cost a lot of money to purchase and set up on your site, and would need constant 24/7 management to make sure it keeps working. Other costs include a broadband Internet service, a cooled airtight room, and an upgraded electrical system with backup power.
Throughout the world are industrial-cooled vault-like rooms that contains equipment cabinets with virtual servers. They are maintained constantly and protected from unauthorized access, and are connected to the Internet. The same server you need is already available over the Internet. You only need to subscribe to the service and and upload your encyclopedia database and viola! you are live!
Benefits of a Virtual Server
- Lower cost to set up and maintain
- Lesser risk of loss when hardware is compromised
- No exorbitant bandwidth required for your own Internet connection
There are a few cons, though. You need to sign up with a reputable virtual server provider who will allow privileged access to your information. Many providers have privacy policies that govern the information stored on their servers to protect your interests. Since the virtual server is available over the Internet, you won't have access if you lose your Internet connection. You would also have no control over the company's hardware or software upgrade schedule.
Virtual servers are the future of computing. Google Inc. jas already launched their chrome book, a laptop whose data and applications are store on a virtual server. They are the home to a growing number of applications, perhaps even your.
