Lower IT administration costs. Thin clients are managed almost entirely at the server.
The hardware has fewer points of failure.
|
|
Easier to secure. Thin clients can be designed in such a way that no application
data ever resides on the client, centralizing malware protection and reducing the
risks of physical data theft.
|
|
Lower hardware costs. Thin client hardware is generally cheaper because it does
not contain a disk, application memory, or a powerful processor.
|
|
Less Energy Consumption. Dedicated thin client hardware has much lower energy consumption
than thick client PCs. (Save around 51K – 20 system network)
|
|
Less network bandwidth. This is contrary to normal belief - BUT IT IS TRUE
|
|
Since terminal servers typically reside on the same high-speed network backbone
as file servers, most network traffic is confined to the Server.
|
|
In a fat client environment if you open a 10MB document that's 10MB transferred
from the file server to your PC. When you save it that's another 10MB from your
PC to the server. When you print it the same happens again – another 10MB over the
network to your print server and then 10MB onward to the printer. This is highly
inefficient.
|
|
In a thin client environment only mouse movements, keystrokes and screen updates
are transmitted from/to the end user. This can consume as little as 10-15 Kbit/s
bandwidths.
|
|
Simple hardware upgrade path.
|
|
If the peak resource usage is above a pre-defined limit, it is a relatively simple
process to add more resources to server (be it power, processing, storage), boosting
resources to exactly the amount required.
|
|
The existing units can continue to serve alongside the new.
|
|
Whereas a thick client model requires an entire desktop unit be replaced, resulting
in down-time for the user, and the problem of disposing of the old unit.
|
|
Less Wasted Hardware. Computer hardware is very environmentally damaging. Thin clients
can remain in service longer and ultimately produce less surplus computer hardware
than an equivalent thick client installation.
