Abstract

Moving applications from the mainframe to distributed environments often comes with the expectation of cost savings. However, studies reveal a conclusion that is counter to conventional wisdom.


  • It could actually cost less to stay and grow on the mainframe than to move to a distributed systems environment
  • Hidden costs often inflate the actual cost of moving mainframe-based applications to a distributed environment
  • Workloads running on the mainframe are often a best fit for that platform, and administrators achieve significant operational efficiencies on a consolidated mainframe platform

This IBM® Redbooks® Point-of-View publication discusses why the actual cost of moving applications from the mainframe to distributed environments might be greater than you think.
