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 Cinder block storage service provides block storage volumes as a service. Cinder allows creating block-device volumes and attaches them to Nova virtual machine instances. Cinder supports multiple vendors backend drivers which allows utilizing various storage devices, such as local logical volume management (LVM), NetApp, EMC storage arrays, and others. Cinder accesses the storage device via its management access and lets a Nova virtual machine instance access volumes directly via the storage path. The storage path depends on the implementation of the storage array and could be an iSCSI target, fiber channel, or other.

It is important to note that Cinder is not a shared storage solution such as a storage area network (SAN) that allows attaching a volume to multiple servers. Cinder allows attaching a volume to only one instance at a time.

Native cloud applications are stateless by nature; thus, the Nova virtual machine instance does not save any data on the ephemeral disk...
