Google Cloud has extended its mainframe migration services to include a new option that enables parallel processing – customers can simultaneously run their mainframe workloads on prem and in the cloud, with the ultimate goal of moving those resources to the cloud.
The new service, Dual Run for Google Cloud, is in preview status and lets customers run workloads on their existing mainframes and on Google Cloud concurrently without interrupting operations. Enterprises can then perform real-time testing and determine application performance and stability in the cloud.
A large challenge with mainframe systems is the tight coupling of data to the application layer. Companies would have to stop an application for some period of time in order to move it, modernize it or transform it, according to Google.
