Migrating an
entire mainframe to the cloud.

Working with LzLabs, Swisscom migrated its entire mainframe application workload and data to a cloud infrastructure running the LzLabs Software Defined Mainframe® (SDM).

The challenge.

  • To relieve pressure from a highly competitive market, and reduce IT costs
  • Minimize the risk of a declining mainframe skills pool
  • Position Swisscom for innovation in the communications industry

The solution.

  • Business-critical applications now run on Linux
  • Mainframe staff trained to manage applications in a modern, open environment
  • The base was set for a new, highly competitive offering on the Swisscom Enterprise Services Cloud

It works. It really works.
You need to have the courage, and you have to face a change project, but it works. Go for it”

— Markus Tschumper, head of General IT Services, Swisscom
