OpenStack for Architects - Second Edition

By: Michael Solberg, Ben Silverman

Overview of this book

Over the past six years, hundreds of organizations have successfully implemented Infrastructure as a Service (IaaS) platforms based on OpenStack. The huge amount of investment from these organizations, including industry giants such as IBM and HP, as well as open source leaders, such as Red Hat, Canonical, and SUSE, has led analysts to label OpenStack as the most important open source technology since the Linux operating system. Due to its ambitious scope, OpenStack is a complex and fast-evolving open source project that requires a diverse skill set to design and implement it. OpenStack for Architects leads you through the major decision points that you'll face while architecting an OpenStack private cloud for your organization. This book will address the recent changes made in the latest OpenStack release i.e Queens, and will also deal with advanced concepts such as containerization, NVF, and security. At each point, the authors offer you advice based on the experience they've gained from designing and leading successful OpenStack projects in a wide range of industries. Each chapter also includes lab material that gives you a chance to install and configure the technologies used to build production-quality OpenStack clouds. Most importantly, the book focuses on ensuring that your OpenStack project meets the needs of your organization, which will guarantee a successful rollout.

Network design


The network requirements for a particular OpenStack deployment also vary widely depending on the workload. OpenStack also typically provides an organization's first experience with Software-Defined Networking (SDN), which complicates the design process for the physical and virtual networks. Cloud Architects should lean heavily on their peers in the network architecture team in the planning of the network.

Providing network segmentation

OpenStack's roots in the public cloud provider space have left a significant impact on the network design at both the physical and virtual layer. In a public cloud deployment, the relationship between the tenant workload and the provider workload is based on a total absence of trust. In these deployments, the users and applications in the tenant space have no network access to any of the systems that are providing the underlying compute, network, and storage. Some access has to be provided for the end users to reach the API endpoints of the OpenStack...
