Thin Clients are Suitable for a Wide Range of Applications
TFA: "thin client solutions are not appropriate for a wide range of business activities"
Not so. Only full-screen video with its large bandwidth requirements is a no-no for thin clients. Even then for a few users of full-screen on a server it can be done. For most other uses, bandwidth actually is less for thin clients than traditional PCs with files on the server. It is much less effort to move a few text and pictures over the LAN than a bunch of data-files. Thin clients may increase the average or minimum load on a network but the peak loads will be much less.
We can also look at the functionality of the working parts of a PC to see the waste. Besides energy, look at the wasted expenditure on hard drives. If you have 100 PCs with 100 hard drives instead of 100 thin clients with far fewer drives on the server, the advantage is obvious. Same for CPUs. Why have 100 powerful CPUs idling on thick clients when you could have a low-powered CPU working reasonably hard on the thin client and a few powerful CPUs working hard on the server? Thick clients just make no sense. The presumption should be that all client machines will be thin unless there is a particular reason to go thick.
Moore's Law will allow us to push more processes into the server room but nothing will recover the waste of resources on the thick clients forever into the future. You can break even on the cost of a changeover to thin clients in a year or two in energy but there are immediate returns on investment in lower maintenance and longer life that are so solid this technology should be the norm.
Where I work, the cost of old PCs is so low that we do not buy new thin clients but the performance increase obtained by using old PCs as thin clients of fast new servers is all the justification I need. My users boot and login twice as fast as they used to do with thick clients and I have almost no work to do to keep them running. It is a clear win.
