Increased speed to market

Accelerate delivery through rapid development and testing enabled by on-demand access to a z/OS environment in less than 5 minutes.

Innovation with freedom

Innovate faster in response to ever-changing business needs by using a z/OS system that includes the latest and greatest software.

Improved software quality  and compliance

Enhance software quality and auditability by shifting left and automating your testing and considering security earlier in the development lifecycle.

Increased productivity

Help developers and systems programmers by eliminating wait times and enabling easy deployment of a z/OS system with Wazi Image Builder using standard or custom images.

Greater scalability

Enable horizontal and vertical scaling on demand based on business needs and pay only for what you use with infrastructure available as a service in a flexible consumption model.

Flexible deployment

Deploy an IBM-provided dev and test stock images on the z/OS Virtual Server, or bring a custom image for applications and related components to deploy to the z/OS Virtual Server in VPC.

Development and testing Leverage the strength and security of IBM Cloud with self-serve access to z/OS systems and create standard or custom images from your own LPAR. Get started with development and testing in minutes without any dependency on operations. Watch the video (4:05)

Infrastructure testing Overcome the issues of broken processes, insufficient security and more that are preventing you from testing software upgrades at speed. Expedite testing with a z/OS virtual server instance (VSI) and Wazi Image Builder.

Innovation and skill building Accelerate innovation by lowering the barrier to entry for new z/OS developers and reduce their need to have specialized skills by providing easy access to preinstalled and customized software available as stock images.
