  With a company that hosts a substantial amount of traffic, a dedicated server will be required.
  
  

How it is used

  Complex and high-end e-commerce sites require a lot of space, security and bandwidth speeds of over 10 Mb/s. These dedicated servers act as data centers with redundant power sources, HVAC systems and stable Internet connections.
  
  

Redundancy

• Virtual dedicated servers make redundancy possible, which is where the same application is run on multiple servers. Redundancy ensures operations like business transactions can go on with minimal interruption.

  A virtual dedicated server can also be configured to allow machines to run Honeypots - software with known security flaws. These help the IT staff gain better insights into computer security.
