Learning OpenStack Networking - Third Edition

By: James Denton

Overview of this book

OpenStack Networking is a pluggable, scalable, and API-driven system to manage physical and virtual networking resources in an OpenStack-based cloud. Like other core OpenStack components, OpenStack Networking can be used by administrators and users to increase the value and maximize the use of existing datacenter resources. This third edition of Learning OpenStack Networking walks you through the installation of OpenStack and provides you with a foundation that can be used to build a scalable and production-ready OpenStack cloud. In the initial chapters, you will review the physical network requirements and architectures necessary for an OpenStack environment that provide core cloud functionality. Then, you’ll move through the installation of the new release of OpenStack using packages from the Ubuntu repository. An overview of Neutron networking foundational concepts, including networks, subnets, and ports will segue into advanced topics such as security groups, distributed virtual routers, virtual load balancers, and VLAN tagging within instances. By the end of this book, you will have built a network infrastructure for your cloud using OpenStack Neutron.

Summary

At this point in the installation, the OpenStack Identity, Image, Dashboard, and Compute services have been successfully deployed across the nodes of the cloud. The environment is not ready to host instances just yet, as OpenStack Networking services have not been installed or configured. If issues arise during the installation of services described in this chapter, be sure to check the log messages found in /var/log/nova/, /var/log/glance/, /var/log/apache2/, and /var/log/keystone/ for assistance in troubleshooting. For additional information regarding the installation process, feel free to check out the documentation available the OpenStack website at the following URL: http://docs.openstack.org.

In the next chapter, we will begin the installation of Neutron networking services and discover additional information about the internal architecture of OpenStack Networking...
