respond by resisting or embracing the heterogeneity.
While many technology providers have succumbed to the
temptation to conquer complexity by reducing the computing
environment to a single technology platform, this approach
can result in a case of throwing the baby out with the bathwa-
ter. After all, different technologies are better suited to run
different workloads, whether transaction and data processing,
analytics, web-based interactions or enterprise applications.
That’s why IBM believes it’s smarter to keep multiple tech-
nologies and find better ways for them to work together.
That’s the thinking behind the IBM zEnterprise™ System.
zEnterprise: The basis for a truly
integrated hardware environment
zEnterprise is an integrated hardware platform that’s
designed to span and manage workloads across mainframe,
IBM POWER7® and IBM System x® blade technologies.
