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.

Neutron is a software-defined networking service for OpenStack. OpenStack is responsible for managing virtual machine instances, and Neutron networking service is responsible for the network connectivity between virtual machine instances, tenants, and connectivity to external public networks allowing access to OpenStack virtual machine instances.

To provide the basic network connectivity to virtual machine instances, Neutron uses software-defined virtual switches. Neutron offers three types of capabilities, which are Neutron's core entities:

  • Network: Networks are isolated Layer-2 broadcast domains, and they can also be regarded as the hubs that virtual machine instances connect to for interconnectivity.

  • Subnet: A subnet is a block of IPv4 or IPv6 address that is associated with a network. The IP address for a subnet can be assigned to virtual machine instances. Multiple subnets can reside in a single network. A DHCP service can be used to assign the IP address from the address...
