If one server fails the cluster responds by not sending traffic to it. Servers maintain the same data by using replication Terminal Services Based off of old Mainframe and Dumb Terminal Architecture Now You Use Terminal Services Servers and Thin Clients Thin Clients can be Hardware Devices or Software installed on a computer All processing happens on Terminal Services Server and the Thin Client simply gets a "Window" into the server.

  Cloud Computing

  A lighter look at what's possible when IT systems are dynamic and smarter. Workstations used to be connected to a mainframe. Now they're conversing with a cloud. Information technology is changing rapidly, and now forms an invisible layer that increasingly touches every aspect of our lives. Power grids, traffic control, healthcare, water supplies, food and energy, along with most of the world's financial transactions, all now depend on information technology. An emerging compute model - cloud computing - addresses the explosive growth of internet-connected devices, and complements the increasing presence of technology in today's world. Cloud computing is massively scalable, provides a superior user experience, and is characterised by new, internet-driven economics.
