Feilong: Updates & a new Demo

Feilong is a z/VM Cloud Connector that provides virtual resource management for z/VM. Users can manage the VM lifecycle dynamically and automatically without deep knowledge of z/VM itself through REST API. Users do not need to manually provision, manage, and destroy guests. Feilong also provides an SDK to make it easy to develop system management tools. Fundamentally, Feilong allows IaaS/PaaS solutions such as OpenStack™ or Terraform to consume z/VM by providing REST APIs, making time to market faster.

Feilong represents a set of capabilities providing virtual resource management to z/VM that clients and ISVs otherwise find via libvirt (for a broad variety of hypervisor offerings, open source and proprietary) or VMware vCenter APIs elsewhere in the industry with an x86 focus.

The key benefits for users of Feilong include:

REST API and client tools

so that users don’t need to have manual actions in order to provision, manage, destroy guests on z/VM

SDKs to end user


to make it easier to develop system management tool for z/VM

IaaS/PaaS solutions


such as OpenStack/Terraform are able to be consumed by providing REST APIs to make time to market faster
