OpenStack for Architects

Chapter 2. 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 Liberty release of OpenStack (November 2015), there were over 50 Cinder storage drivers and 20 Neutron network drivers. These 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.

Few of the decisions we make as architects affect the bottom line as much as hardware and software selection. While we approach the deployment of our cloud or the development of our software in an iterative fashion to reduce the risk of mistakes...

Picking an OpenStack distribution

OpenStack is developed like most open source software projects. The code is available at http://openstack.org and can be downloaded in the package format from http://tarballs.openstack.org. As of the Liberty release of OpenStack, there were over 350 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, available at http://docs.openstack.org. There are also distributions available from companies such as HP, Mirantis, and Red Hat which are part of commercial support agreements. In addition to these options, there are also companies...

Compute hardware considerations

It's certainly possible to deploy OpenStack on Power or Z series systems from IBM or Solaris systems from Oracle, but the vast majority of OpenStack deployments use Linux on 64-bit Intel systems. 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 which had to be reconfigured after the fact. We'll try to help you avoid that second purchase...

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 which are providing the underlying compute, network, and storage. Some access has to be provided for the end users to reach the API endpoints...

Storage design

As compute hardware has become less expensive over the last 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 for presenting many different kinds of storage with a single interface. This capability allows tenants to choose the storage which 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 for instance live migration, backup, and recovery.

Ephemeral storage

Ephemeral storage is the storage that is consumed when a Glance image is copied locally to a compute node to instantiate a virtual instance. Glance images are typically...

Description

Over the last five years, hundreds of organizations have successfully implemented Infrastructure as a Service (IaaS) platforms based on OpenStack. The huge amount of investment from these organizations, industry giants such as IBM and HP, as well as open source leaders such as Red Hat have led analysts to label OpenStack as the most important open source technology since the Linux operating system. Because of its ambitious scope, OpenStack is a complex and fast-evolving open source project that requires a diverse skill-set to design and implement it. This guide leads you through each of the major decision points that you'll face while architecting an OpenStack private cloud for your organization. At each point, we offer you advice based on the experience we'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, we focus on ensuring that your OpenStack project meets the needs of your organization, which will guarantee a successful rollout.

While reading the book, Pike was the released version. It seems most of the book is referring to the Newton release. That doesn’t matter though. The book gives a great overview and helps you establish a list of things to consider before building your own cloud.

This is a very nice & decent study outcome from experiences of Authors!If you are newbie Cloud Solution Architect started to work with Openstack Services as technology, this book will provide you good level of guidance to design, implement and test a Proof Of Concept Project.However if you truly go in Production Level of Solution Design this book may not be that helpful as it does not cover;(a) Network Blue Print Design; decisions for flat, overlay, vlan networks with traffic calculations (CSO requirements) that will point certain NIC types (ex SR-IOV, DPDK support), Integration to Physical Network Fabric (ML2 Plugin, SDNc integrations). These are covered in 2 pages in this book with brief overview.(b) Storage Backend Design/Requirements for your Cloud Workloads; what sort of IOPs your vApp/VNFs will need to come in to service based on KPI requirements. Not covered at all in this book.(c) Openstack Upgrades, what are the best practices and how to do it? Specially if you have in-service sites and suffering from missing features that are already available in new Openstack releases. Instead patching has a section in the name of security hardening thats all.(d) Using Containers for Openstack Services and as well as light weight workload hypervisor selection. Only mentioned as future/emerging trends.

Why authors or Amazon don't explain the requirements, so the Operating System covered, and the OpenStack's version covered.Why they don't explain that the book uses the all in one?As requirements, on page 21 they say "Red Hat Enterprise Linux 7 (or CentOS 7)".I do my own makes of OpenStack in distributed Servers, so why they don't explain clearly that I won't find any of this?.For the price I paid I'm not happy.Still it has good information.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
