Hybrid Orchestration with IBM Z – Dong Ma, Software Engineer at IBM

There are multiple workloads running on x86, Power or Z, and even for Z workloads there are multiple technical implementations like z/VM, KVM, PR/SM(Processor Resource/System Manager) or even zCX (z/OS container extension) or event native z/OS. Challenges comes when you have to manage all those workload all together, especially those core systems are building across different technical stacks, how to unify and simplify the management for all those different infrastructure stacks, specifically some of those workloads(like z/OS workload and zCX workload) can decrease network latency and therefore, improve IO performance while running under certain co-location rules. With this talk we will present how to manage different hypervisor resources like z/VM guest, KVM guest or zCX (z/OS container extension) guest so that all those infrastructure can be integrated with cloud management tools to provision and orchestrate along with the cloud workloads
