OpenStack for Architects

Architecting the Cloud

The array of possible hardware and software combinations that can be used to create an OpenStack cloud is pretty amazing at this point. A phrase we typically hear these days is that having an integration for OpenStack is table stakes for a hardware or software product coming in the market. As of the Queens release of OpenStack (March 2018), there were 75 Cinder storage drivers and over 40 Neutron network plugins. These integrations cover a wide range of products from traditional EMC storage arrays and Cisco switches to various software-defined storage and networking products. OpenStack supports a number of hypervisors and compute platforms, ranging from commodity x86 hardware to IBM Z-series mainframes.

A few of the decisions we make as architects affect the bottom line as much as hardware and software selection. Although we approach the deployment of our...

Picking an OpenStack distribution

OpenStack is developed like most open source software projects. The code is available at http://openstack.org, and it can be downloaded in the package format from: http://tarballs.openstack.org. As of the Queens release of OpenStack, there were over 700 individual projects available for download. That's a huge number of source repositories for an engineering team to sort through and manage, hence the development of the OpenStack distributions. Most of the OpenStack distributions are put together by the same groups that put together Linux distributions. For example, the three major distributions available are part of the Ubuntu, openSUSE, and CentOS Linux distributions. Each of these distributions maintain installation guides, which are available at: http://docs.openstack.org. There are also distributions available from companies...

Compute hardware considerations

Selecting a hardware platform for compute infrastructure in OpenStack is similar to selecting a hardware platform for any other workload in the data center. Some organizations have a brand loyalty to a particular vendor based on reputation, past performance, or business arrangements, and some organizations ask hardware vendors to bid on projects as they come up. A small number of organizations choose to assemble their own systems from components, but most OpenStack deployments use the same commodity systems that would be deployed to run any other Linux workload.

With that said, we've definitely seen hardware configurations that work well with OpenStack and ones that had to be reconfigured after the fact. We'll try to help you avoid that second purchase order in this section.

...

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...

Storage design

As compute hardware has become less expensive over the past few years, fewer and fewer workloads are constrained by a lack of processor or memory performance. Instead, most workloads are tuned so that they are constrained on I/O—particularly, storage I/O. OpenStack workloads typically separate the operating system storage from the application storage and Cinder, and the different object storage projects provide mechanisms to present many different kinds of storage with a single interface. This capability allows tenants to choose the storage that matches their application's requirements. In addition to Cinder providing persistence for applications, block storage and object storage also provide storage persistence for instances and allow instance live migration, backup, and recovery.

...

Expanding the initial deployment

To properly evaluate the different compute, network, and storage options we've discussed in this chapter, an expanded OpenStack deployment with dedicated roles for different physical systems is required. Separating the compute functions from the control functions allows us to properly test different types of compute hardware. Separating storage functions from compute and control functions allows us to properly test different disk, NAS, or SAN configurations. In this section, we'll split out the roles we deployed in Chapter 1, Introducing OpenStack, to three physical systems. Each of these systems will be assigned a role, which we'll call a host group.

Updating the design document

...

Summary

OpenStack deployments are often compared with snowflakes. There are so many different ways to combine the various supported compute, storage, and network configurations that no deployment resembles any other deployment. This analogy is frequently used in frustration at companies that offer commercial support for OpenStack—the diversity of deployments makes supporting customers extremely difficult. Many of the clients we work with have also expressed frustration at the myriad of options available. On the other hand, most of the people who have been running OpenStack for a while realize the value of having so many options. It allows them to continually provide new services and capabilities to their customers under a common interface.

In this chapter, we walked through each of the three major areas of technology in OpenStack—compute, network, and storage. In...

  • Create a robust virtual environment for your organization
  • Design, implement and deploy an OpenStack-based cloud based on the Queens release

Description

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.

Who is this book for?

OpenStack for Architects is for Cloud architects who are responsible to design and implement a private cloud with OpenStack. System engineers and enterprise architects will also find this book useful. Basic understanding of core OpenStack services, as well as some working experience of concepts, is recommended.

I really enjoyed this book. As an architect of other platforms, this book gave me a holistic look at OpenStack and some of the use cases that are being applied to it today. I really enjoyed the operations, security and monitoring sections, but the cloud planning chapters were invaluable. I highly recommend this book!

Buen libro pero para ser "para arquitectos" hay demasiada información sobre la implementación de los ejemplos y poca sobre la arquitectura tanto física como lógica.

I liked that this book gave a broad overview of OpenStack, which does not seem to readily available elsewhere. I also like that it was fairly opinionated and gave some good practical advices, while also describing other options. I would agree that it does not get too deep into the details, but perhaps that is not what this book it about. I recommend it.There was some terrible formatting the the Kindle Cloud Reader at pages 63-64, and 79-91 which made those pages unreadable. These formatting errors did not appear in the Android Kindle app, or on an actual Kindle.
