This video is a technical overview of IBM Virtual Dev and Test for z/OS. ZVDT provides a non-production, isolated IBM Z environment running on Linux on IBM Z or LinuxONE, on-premise. Users can build mainframe applications, test and implement code and environment changes before deploying to production, and create learning environments to educate new z/OS learners.  By removing barriers to testing, ZVDT can accelerate code delivery and improve software quality by shifting testing to early in the development cycle.
