Google Cloud announced Modernize, an end-to-end transformation portfolio bundling Migration Center, VMware Engine, mainframe modernization, and a new EKS-to-GKE Migration Agent. Its centerpiece, the in-console Modernization Hub, analyzes source code and maps dependencies for Java, .NET, and mainframe apps.
