Overview of this book

In this second edition, you will get to grips with the latest features of OpenStack. Starting with an overview of the OpenStack architecture, you'll see how to adopt the DevOps style of automation while deploying and operating in an OpenStack environment. We'll show you how to create your own OpenStack private cloud. Then you'll learn about various hypervisors and container technology supported by OpenStack. You'll get an understanding about the segregation of compute nodes based on reliability and availability needs. We'll cover various storage types in OpenStack and advanced networking aspects such as SDN and NFV. Next, you'll understand the OpenStack infrastructure from a cloud user point of view. Moving on, you'll develop troubleshooting skills, and get a comprehensive understanding of services such as high availability and failover in OpenStack. Finally, you will gain experience of running a centralized logging server and monitoring OpenStack services. The book will show you how to carry out performance tuning based on OpenStack service logs. You will be able to master OpenStack benchmarking and performance tuning. By the end of the book, you'll be ready to take steps to deploy and manage an OpenStack cloud with the latest open source technologies.

Deciding on the hypervisor

The hypervisor is the heart of your OpenStack compute node. This is called the virtual machine monitor (VMM), which provides a set of manageability functions for virtual machines to access the hardware layer. The amazing part about hypervisors in OpenStack is the wide range of VMMs that it can offer, including KVM, VMware ESXi, QEMU, UML, Xen, Hyper-V, LXC, bare metal, and lately, Docker.

If you already have some experience with one or more of these, it will be better to take a look at how they differ at an architectural level. Currently, the latest OpenStack release at the time of writing this book is Ocata, which has many hypervisor features added or extended. Keep in mind that not all of these support the same features. The Hypervisor Support Matrix (https://wiki.openstack.org/wiki/HypervisorSupportMatrix) is a good reference that can help you to choose what fits your needs.
