By: Omar Khedher, Chandan Dutta

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.

Segregating the compute cloud

As your cloud infrastructure grows in size, you need to devise strategies to maintain low latency in the API services and redundancy of your service. To cope with unplanned downtime due to natural forces or based on the hypervisor capability itself, the operator must plan for service continuity.

OpenStack Nova provides several concepts that help you segregate the cloud resources. Each segregation strategy brings in its own advantages and shortcomings. We must have a discussion to understand the tools available with an OpenStack cloud operator to manage the need for scale and availability of compute servers.

Availability zones

The concept of Availability Zones (AZ) in Nova is to group together compute nodes based on fault domains: for...
