Production Ready OpenStack - Recipes for Successful Environments

By: Arthur Berezin

Overview of this book

OpenStack is the most popular open source cloud platform used by organizations building internal private clouds and by public cloud providers. OpenStack is designed in a fully distributed architecture to provide Infrastructure as a Service, allowing us to maintain a massively scalable cloud infrastructure. OpenStack is developed by a vibrant community of open source developers who come from the largest software companies in the world. The book provides a comprehensive and practical guide to the multiple uses cases and configurations that OpenStack supports. This book simplifies the learning process by guiding you through how to install OpenStack in a single controller configuration. The book goes deeper into deploying OpenStack in a highly available configuration. You'll then configure Keystone Identity Services using LDAP, Active Directory, or the MySQL identity provider and configure a caching layer and SSL. After that, you will configure storage back-end providers for Glance and Cinder, which will include Ceph, NFS, Swift, and local storage. Then you will configure the Neutron networking service with provider network VLANs, and tenant network VXLAN and GRE. Also, you will configure Nova's Hypervisor with KVM, and QEMU emulation, and you will configure Nova's scheduler filters and weights. Finally, you will configure Horizon to use Apache HTTPD and SSL, and you will customize the dashboard's appearance.

About the Reviewers


Many organizations choose OpenStack for its distributed architecture and ability to deliver the Infrastructure as a Service (IaaS) platform for mission-critical applications. In such environments, it is crucial to configure all OpenStack services in a highly available configuration to provide as much possible uptime for the control plane services of the cloud. Deploying a highly available control plane for OpenStack can be achieved in various configurations. Each of these configurations would serve a certain set of demands and introduce a growing set of prerequisites.

This chapter expands the OpenStack services configuration described in Chapter 1, Introduction to OpenStack and its Deployment Using Packages, and discusses how to configure each of the OpenStack services, database, and message broker in a highly available configuration. Pacemaker is used to create active-active clusters to guarantee services' resilience to possible faults. Pacemaker is also used to create a virtual...
