This guide leads you through each of the major decision points that you'll face as you architect an OpenStack private cloud for your organization. At each point, we offer you advice based on years of experience designing and leading successful OpenStack projects in a wide range of industries. Each chapter also includes lab materials that give you a chance to install and configure the technologies used to build production-quality OpenStack clouds. Most importantly, we focus on ensuring that your OpenStack project meets the needs of your organization, which will guarantee a successful roll-out.
Chapter 1, Introducing OpenStack, helps you familiarize yourself with the components of OpenStack.
Chapter 2, Architecting the Cloud, explains the software, hardware, network, and storage selection options for OpenStack.
Chapter 3, Planning for Failure (and Success), covers techniques of increasing the scalability and availability of the cloud.
Chapter 4 , Building the Deployment Pipeline, shows how to use the concepts of DevOps to create a continuously integrated and delivered OpenStack deployment.
Chapter 5, Building to Operate, explains how to architect a private cloud that is optimized for operations.
Chapter 6, Integrating the Platform, reveals three different integration patterns for OpenStack clouds.
Chapter 7, Securing the Cloud, introduces how to design a private cloud that is secure from the beginning.
Chapter 8, Conclusion, covers creating a compelling road map for the future of Infrastructure as a Service in your organization.
All of the software used in the examples in this book is available at no cost on the Internet. Links are provided for each of the projects used. Many of the lab exercises require access to physical hardware. We recommend having at least four and up to 12 physical servers available for deploying OpenStack.
This book is written especially for those who will design OpenStack clouds and lead their implementation. These people are typically cloud architects, but may also be in product management, systems engineering, or enterprise architecture.
In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.
Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The
keystonerc_admin file can be used to authenticate an administrative user and the
keystonerc_demo file can be used to authenticate a non-privileged user."
A block of code is set as follows:
export OS_USERNAME=demo export OS_TENANT_NAME=demo export OS_PASSWORD=<random string> export OS_AUTH_URL=http://192.168.0.10:5000/v2.0/ export PS1='[\u@\h \W(keystone_demo)]\$ '
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
export OS_PASSWORD=<random string>
export PS1='[\u@\h \W(keystone_demo)]\$ '
Any command-line input or output is written as follows:
# yum install -y openstack-packstack
New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Click on the Manage Jenkins link in the left-hand navigation."
