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.

The front and center of Infrastructure as a Service (IaaS) solution is the compute service that runs the Cloud application workloads. OpenStack Compute, named project Nova, is responsible for providing computing as a Service framework for OpenStack that enables provisioning and managing the life cycle of instances of virtual machines at a large scale. Nova allows us to create, manage, and destroy virtual machine instances using API calls. Nova also has a complete command-line tool interacting with the API.

Nova's architecture is designed to scale horizontally on standard hardware, which allows us to create a highly scalable Cloud environment.

To implement Compute as a Service and manage large amount of virtual machine instances that can rapidly scale out, Nova uses several Linux services that fall under the following categories:

Nova access services

  • The nova-api service provides an API that the user interacts with. Nova-API supports an OpenStack native Compute API and Amazon EC2...
