18-3 Distributed Server
Several applications are configured as Servers for direct connection, so the
data for the system is 'distributed' across several machines. One or more
Client applications collect the data from the distributed servers. This can be
useful to help performance, by distributing the communication on the device
connections, and server processing. It can also provide different security for
different clients and offers limited protect against failures, as remaining
servers still function.
18-4 Redundant Server
Several applications are configured as Servers for direct connection to the
same Devices or Device network. The same data is collected by all Servers.
One or more clients can collect the data from any single Server, and in the
event of a Server failure, can be written to switch to data from an alternative
Server.
