PARSEC Resources for z/OS

z/OS runs the most demanding, mission-critical workloads in the enterprise — and keeping it running takes deep, specialized expertise that’s getting harder to find as an experienced generation of mainframe professionals retires. PARSEC delivers that expertise: full support, operations, system programming, and application services for your z/OS environment.

Whether you want fully managed Mainframe-as-a-Service in a private cloud or remote support that keeps your hardware exactly where it is, PARSEC has you covered — US-based, direct-to-expert, 24/7. And because we know our stuff across most major platforms, you can count on us for much more.

Why PARSEC for z/OS

z/OS expertise, direct-to-expert, since 1986.

PARSEC keeps mission-critical z/OS environments running — managed or remote, US-based, 24/7 — with the deep specialized skills that are getting harder to find.

24/7

Deep z/OS Expertise

System programming, operations, production control, storage and tape management, performance tuning — PARSEC’s engineers work the full z/OS stack, including the DB2, IMS, and VSAM data layers that run underneath your applications.

Managed or Remote

Run z/OS fully managed as Mainframe-as-a-Service in a PARSEC private cloud, or keep your hardware in place and let our team support it remotely. Flexible contracts and SLAs built around your needs, not ours.

Workforce Transition

Application Services Too

Beyond the OS, PARSEC’s application programmers maintain and modernize the software that runs your business — COBOL, Assembler, PL/I, Natural, ADABAS, Java — from day-to-day support through modernization.
