Past
Mainframe
It is a large self-contained unit with
centralized data storage and resource
administration, and multiple layers of
redundancy for every component: power
supplies, cooling, backup batteries, CPUs,
I/O components, and cryptography
modules.
Present
Server-based
The maintenance and redundancy needs
of server farms can be effectively nullified
by automation and orchestration tools,
making them more easily managed than
mainframes.
