Today’s mainframe is part of a complex ecosystem which includes on-prem, colocation, hosted, cloud and edge services.
The mainframe carries historical baggage. The platform is frequently seen as too expensive; inflexible and slow to change; poorly integrated with the rest of Hybrid IT. It carries the concerns that changing workforce demographics create a sustainability risk.
Yet replatforming is a risky, complex, multi-year effort which can result in higher costs long-term, and almost always results in higher costs over the near term.
GTSG is the only firm recognized by Gartner for both mainframe expertise and competency in Hybrid Cloud Workload Placement Strategy.
