Cattle Wrangling For Pet Whisperers: Building A Multi-hypervisor Cloud
This document discusses building a multi-hypervisor OpenStack cloud with both KVM and vSphere. It clarifies that VMware is a company, not a product, and that OpenStack can manage multiple hypervisors including KVM and ESXi. The document focuses on principles for building resilient clouds, including scaling out rather than up, ensuring application resiliency, and treating virtual machines as cattle rather than pets. It also addresses using vSphere with OpenStack and the architecture of a multi-hypervisor OpenStack cloud.

- 13. 13 Use Cattle NotPets • Virtual Machines needs care and feeding – Name the VM – Tune and groom regularly – Feed pets with good food and supplements – Take pets to the vet when they are sick • Cloud servers are disposable – VMs are not unique – Tune and groom apps not the cattle – Replace when necessary – Shoot the cattle when it is sick
