Our take on Astadia
Astadia brings focused expertise to mainframe modernization, positioning replatforming as the fastest and most cost-effective path to legacy transformation. The Phoenix-based company has successfully delivered modernization for enterprises and government institutions including the United States Air Force.
Their approach begins with discovery stage analysis of application code and products, building detailed plans essential for successful projects. Expert teams move legacy workloads from mainframe environments to cloud-ready solutions optimized for Linux, Unix, or Windows deployment environments.
Astadia emphasizes that modernization goes beyond running mainframe applications on cheaper platforms—it creates a bridge to the future. World-class public cloud environments provide low-cost, robust infrastructure with typical savings of 60-80%, while enabling business agility for growth and market responsiveness.
Their solutions address the shrinking pool of mainframe software engineers by moving to platforms with ever-increasing developer availability. Applications move with minimal code changes, operating exactly as they did on the mainframe.
