19. THIS SEEMS COMPLETELY DIFFERENT
FROM OUR CURRENT ENVIRONMENT—
BETTER, BUT HOW CAN WE AFFORD TO
REPLACE IT WITH ALL THIS NEW STUFF?
Like much technology, a phased approach is often recommended. You can start small with
as few as 3 nodes to run a single workload. Once IT teams see the efficiency of that workload,
they grow their cluster and add additional workloads.
18. ARE WE JUST
REINVENTING
MAINFRAMES?
Nope! Mainframes are monolithic machines
capable of running multiple operating systems.
They are not clustered or distributed technology.
