Mastering OpenStack

Chapter 2. Deploying OpenStack – DevOps and OpenStack Dual Deal

 

"Besides black art, there is only automation and mechanization."

 
 --Federico Garcia Lorca

Deploying an OpenStack environment based on the profiled design, as shown in the previous chapter, is not simple. Although we created our design by taking care of several aspects related to scalability and performance, we still have to make it real. If you are still looking at OpenStack as a single block system, you should take a step back and recheck what was explained in Chapter 1, Designing OpenStack Cloud Architecture.

Furthermore, in the introductory section of this book, we covered the role of OpenStack in the next generation of datacenters. The infrastructure has now become programmable through APIs. However, a large-scale infrastructure used by cloud providers needs a very different approach in order to set it up with a few thousand servers.

In our case, deploying and operating the OpenStack...

DevOps in a nutshell

The term DevOps is a conjunction of development (software developers) and operations (manage and put software into production). Many IT organizations have started to adopt such a concept, but the question is how and what? Is it a job? Is it a process or a part of ITIL best practices?

DevOps is a development and operations compound, which basically defines a methodology of software development. It describes practices that streamline the software delivery process. This is not all. In fact, it is more about raising communication and integration between developments, operators (including administrators), and quality assurance. The essence of the DevOps movement is in the benefits of collaboration. Different disciplines can relate to DevOps and bring their experiences and skills together under the DevOps label to build a cover of shared values.

So, we agree that this is a methodology that puts several disciplines on the same wave length as shown in the following figure:

DevOps in a nutshell

This...

Eat the elephant

At first sight, you may wonder what is the best automation tool that will be useful for our OpenStack "production day". We have already chosen Git and Jenkins to handle our continuous and delivery code infrastructure. It is time to choose the right tool for automation.

Eventually, it might be difficult to select the right tool. Most likely, you'll have to choose between several of them. Covering all the existing IT automation tools could fill an entire book or even books. Therefore, giving succinct hints on different tools might be helpful in order to distinguish the best outfit for certain particular setups. Of course, we are still talking about large infrastructures with heterogeneous systems, a lot of networking, and distributed services.

Giving the chance for one or more tools to be selected as system management parties can be effective and fast for our deployment. We will use Chef for the next deployment phase.

Preparing the infrastructure code environment...

Summary

In this chapter, we covered several topics and terminologies on how to develop and maintain a code infrastructure using the DevOps style.

Bringing your OpenStack infrastructure deployment to code will not only simplify node configuration, but also improve the automation process.

You should keep in mind that DevOps is neither a project nor a goal to attend to, but it is a methodology that will make your deployment successfully empowered by the team synergy with different departments.

Despite the existence of numerous system-management tools to bring our OpenStack up and running in an automated way, we have chosen the Chef server.

Puppet, Ansible, Salt, and others can do the job but in different ways. You should know that there is no one way to perform automation.

Chef is highly flexible and rich with tools that make life easier. In a similar manner, with Vagrant and Chef plugins, we were able to bring in a test environment in a wink.

Although we deployed a basic multinode setup of OpenStack...

I was looking a technical overview of Openstack that was simple enough to provide me a "big picture" view of the various components involved with an Openstack deployment, yet technical enough to actually understand what each component does and how it all fits together. This book did that well.Even with how the organization helped with getting things sorted out in my understanding, the subject matter is still complex and has a learning curve that can be a bit steep. Just getting a handle on the vocabulary of the many software packages involved requires some time. The writing style is a bit dry, which is somewhat expected for a technical book, but it is almost entertainingly noticeable in this book.Overall, I have to give the author credit for taking a large amount of information and organizing it in a manner that makes learning and understanding Openstack easier. If you are considering this book after being frustrated at not finding much in the way of useful tutorials in getting started with Openstack, this is your book.

As always, I bought this book to grow my knowledge about OpenStack. On the earlier chapters the author presents an overview of the architecture and their building blocks. Also explains something about DevOps and it role inside the cloud environment.From the the chapter 1 to 5 is as a walk-through inside the components to consolidate the needed infrastructure to run your private cloud. Looking forward from chapter 6 the book speaks about some more advanced topic as high availability, advanced networking, monitoring, performance tuning, etc.I consider the book a good resource, write an extended book that speak about technology isn't easy and is a valuable effort from the authors, revisors and people involved to get it done.

This is a complete and very interesting book which you can learn from the basics to the advance how to impletent a complete networking security system. at the beginning it goes explaining the theory since the main concept very detail to the configuration of the system. I could I haven't read a book like this before.This comprehensive guide will help you to choose the right practical option and make strategic decisions about the OpenStack cloud environment to fit your infrastructure in production.I really recommend this book because it has all the necessary and covers all the requirements that I have in my job.Wrote by Ruben Oliva Ramos.

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.

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:
