Mastering OpenStack - Second Edition

By: Omar Khedher, Chandan Dutta

Overview of this book

In this second edition, you will get to grips with the latest features of OpenStack. Starting with an overview of the OpenStack architecture, you'll see how to adopt the DevOps style of automation while deploying and operating in an OpenStack environment. We'll show you how to create your own OpenStack private cloud. Then you'll learn about various hypervisors and container technology supported by OpenStack. You'll get an understanding about the segregation of compute nodes based on reliability and availability needs. We'll cover various storage types in OpenStack and advanced networking aspects such as SDN and NFV. Next, you'll understand the OpenStack infrastructure from a cloud user point of view. Moving on, you'll develop troubleshooting skills, and get a comprehensive understanding of services such as high availability and failover in OpenStack. Finally, you will gain experience of running a centralized logging server and monitoring OpenStack services. The book will show you how to carry out performance tuning based on OpenStack service logs. You will be able to master OpenStack benchmarking and performance tuning. By the end of the book, you'll be ready to take steps to deploy and manage an OpenStack cloud with the latest open source technologies.

Looking at the Tacker project

So where does OpenStack fit in to this NFV ecosystem? NFV deployment requires a VIM. We discussed earlier that the VIM manages the compute, storage, and network resources needed to instantiate a VNF. This job can be easily done by a cloud system such as OpenStack. The Tacker project augments the services of OpenStack by providing the NFV manager and NFV Orchestrator components. Let's look at the process of creatiing a VNF instance on an OpenStack deployment.

We start by registering the OpenStack infrastructure as the VIM for deploying VNFs. To do this, navigate to the NFV | NFV Orchestration | VIM Management panel:

Register your OpenStack installation; the local installation is already registered but you can add another one if needed:

Once the VIM is ready, the next step is to add a VNF template. This process is called VNF onboarding. To do this, navigate to the VNF Management...
