What You Will Learn Architect and install the latest release of OpenStack on Ubuntu Linux 14.04 LTS Review the components of OpenStack networking, including plugins, agents, and services, and learn how they work together to coordinate network operations Build a virtual switching infrastructure using reference architectures based on ML2 + Open vSwitch or ML2 + LinuxBridge Create networks, subnets, and routers that connect virtual machine instances to the network Deploy highly available routers using DVR or VRRP-based methods Scale your application with haproxy and Load Balancing as-a-Service Implement port and router-level security using Security Groups and Firewall as-a-Service Provide connectivity to tenant networks with Virtual Private Networking as-a-Service (VPNaaS) Find out how to manage OpenStack networking resources using CLI and GUI-driven methods In Detail OpenStack Neutron is an OpenStack component that provides networking as a service for other OpenStack services to architect networks and create virtual machines through its API. This API lets you define network connectivity in order to leverage network capabilities to cloud deployments. Through this practical book, you will build a strong foundational knowledge of Neutron, and will architect and build an OpenStack cloud using advanced networking features. We start with an introduction to OpenStack Neutron and its various components, including virtual switching, routing, FWaaS, VPNaaS, and LBaaS. You’ll also get hands-on by installing OpenStack and Neutron and its components, and use agents and plugins to orchestrate network connectivity and build a virtual switching infrastructure. Moving on, you’ll get to grips with the HA routing capabilities utilizing VRRP and distributed virtual routers in Neutron. You’ll also discover load balancing fundamentals, including the difference between nodes, pools, pool members, and virtual IPs. You’ll discover the purpose of security groups and learn how to apply the security concept to your cloud/tenant/instance. Finally, you'll configure virtual private networks that will allow you to avoid the use of SNAT and floating IPs when connecting to remote networks. Style and approach This easy-to-follow guide on networking in OpenStack follows a step-by-step process to installing OpenStack and configuring the base networking components. Each major networking component has a dedicated chapter that will build on your experience gained from prior chapters.

The Roman Empire is weakening. In 367 AD, approximately eight years after the great battle at Hadrian's Wall, Roman garrisons begin to hear rumors of barbarian tribes massing to the north. By 449 AD, Attila, the ruler of the Huns, has become the continent's most powerful monarch, his reputation in battle earning him the title "The Scourge of God." Anticipating an imminent attack by the Huns, Roman leaders negotiate with one of Attila's lieutenants, convincing him to play the part of assassin. He is joined on his mission by a Roman citizen, Jonas, an ambassador dispatched to negotiate a peace treaty with the Huns. When the plot is discovered, Jonas becomes a hostage, forced to fight for his captors if he wishes to remain alive. But he soon learns that Attila intends to conquer Rome itself, and is caught between two mighty empires, both poised for one of the greatest conflicts the world has ever seen. Jonas, knowing his life could be forfeit, has the potential to tip the battle in either direction––and his decision will alter the face of Western civilization. For readers of historically nuanced thrillers and adventure stories by authors like Bernard Cornwell and Colleen McCullough. For readers interested in Roman and Barbarian culture and warfare.
