Overview of this book

If you are an OpenStack-based cloud operator with experience in OpenStack Compute and nova-network but are new to Neutron networking, then this book is for you. Some networking experience is recommended, and a physical network infrastructure is required to provide connectivity to instances and other network resources configured in the book.

System requirements

OpenStack components are intended to run on standard hardware that range from desktop machines to enterprise-grade servers. The processors of the compute nodes need to support virtualization technologies, such as Intel's VT-x or AMD's AMD-v technologies.

This book assumes that OpenStack will be installed on physical hardware that meets the following minimum requirements:

Server

Recommended hardware

Notes

Controller node (runs network, volume, API, scheduler, and image services)

Processor: 64-bit x86

Memory: 8 GB RAM

Disk space: 80 GB

Network: Two 1 Gbps network interface cards (NICs)

While a single NIC can be used, it is not recommended, and therefore not addressed in this build.
