ZVDT versus Wazi as a Service:
- ZVDT is oriented toward organizations that require on-premises hosting and direct control over dev/test infrastructure within their own data centers.
- Wazi as a Service is an alternative for organizations that wish to avoid owning and operating IBM Z capacity and prefer a managed cloud offering; cloud operations, billing, and support experience should be evaluated as part of the decision.
ZVDT versus ZD&T:
- ZVDT runs on Linux on IBM Z hardware and is positioned as providing a closer match to IBM Z execution conditions than emulation-based approaches on commodity hardware.
- ZD&T offers accessibility advantages and can be appropriate for training and some development scenarios where hardware-level fidelity is not required.
Non-IBM alternatives:
- Micro Focus/OpenText offerings are frequently considered when the primary objective is modernization or rehosting rather than maintaining native z/OS execution for development and testing.
