A Critical Business System Evolved for the Future

A prominent North American telecommunications company has successfully completed a full mainframe migration, moving its essential business applications and data from their mainframe to a private cloud infrastructure with the help of the LzLabs Software Defined Mainframe®.  This transformation resulted in up to 60% operational cost reductions and remarkable gains in terms of scalability, agility and future readiness.
