Hardware Zero Client Computing Connect Directly To Virtual Pcs Back
Moves the computing power back to the data center, leaving little more than a keyboard and monitor at a users' desk. While thin clients require some local processing power and locally installed software, zero clients eliminate the need for locally installed software and connect directly to virtual PCs back in the data center, usually over an Ethernet connection.
Zero client hardware typically consists of a small box that connects to a keyboard, mouse, monitor and Ethernet connection. The zero client contains network protocols, allowing each of these interface types to be supported over a wired or wireless IP network without a local PC or thin client. Zero clients are connected over the network to applications running on a PC or server located elsewhere on the IP network. When paired with a VDI (virtual desktop infrastructure), zero client solutions become a quick, secure way to deliver applications to users.
Zero client technology offers several advantages over "fat clients," which are also known as traditional PCs:
1. Power use can be greatly reduced.
2. A fat client may use as much as 250 watts of power, a zero client device may use as little as 5 watts
3. Zero client devices cost significantly less than a traditional PC or even a thin client device
4. Zero client solutions are often priced well under $200 per seat
5. When combining zero client computing with VDI, administrators can reduce the number of physical PCs or blades and run multiple virtual PCs on server class hardware
6. With this change, all of the management, support, continuity and failover benefits of a virtual infrastructure are extended to desktops throughout the organization
