Open Stack is a collection of software projects that work together to provide a cloud fabric. Open Stack is one of the fastest growing open source projects in history that unlocks cloud computing for everyone. With Open Stack, you are able to create public or private clouds on your own hardware. The flexibility and control afforded by Open Stack puts the cloud within reach of anyone willing to learn this technology.

Starting with an introduction to Open Stack troubleshooting tools, we’ll walk through each Open Stack service and how you can quickly diagnose, troubleshoot, and correct problems in your Open Stack. Understanding the various projects and how they interact is essential for anyone attempting to troubleshoot an Open Stack cloud. We will start by explaining each of the major components and the dependencies between them, and move on to show you how to identify and utilize an effective set of Open Stack troubleshooting tools and fix common Keystone problems. Next, we will expose you to common errors and problems you may encounter when using the Open Stack Block Storage service (Cinder). We will then examine Heat, the Open Stack Orchestration Service, where you will learn how to trace errors, determine their root cause, and effectively correct the issue.

Finally, you will get to know the best practices to architect your Open Stack cloud in order to achieve optimal performance, availability, and reliability.

This is straight-to-the point guide to fixing your Open Stack cluster. Common problems are identified and suggestions to resolve these problems are presented in a simple, easy-to-understand manner.
