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.

Planning for service recovery

One of the most critical tasks for a system administrator or cloud operator is to plan a backup. Building an infrastructure and starting in production without a disaster recovery background is considered highly risky and you will need to start taking immediate action. We may find a bunch of property software in the cloud computing area that does the job, such as the VMware backup solution.

However, backing up open source clouds will not be that easy. OpenStack does not, for instance, support any special tool for backup. As it is merely a collection of components combined to deliver services, an OpenStack operator should think how to map the components used in its infrastructure and prepare a backup strategy for each; the strategy should be easy, efficient, and auto-recovery enabled.

Thus, you should not miss the first question: what do we need to back up and how do we perform such a...
