In Detail
VMware NSX is the network virtualization and security platform that emerged from VMware. It is a platform for the software-defined data center. This software networking platform allows complex networking topologies to be deployed programmatically in seconds. SDNs allow ease of deployment, management, and automation in deploying and maintaining new networks while reducing and in some cases completely eliminating the need to deploy traditional networks.
In Learning VMware NSX, you will see some of these features of SDN and explore VMware NSX, starting with network virtualization. We'll then walk you through the components of NSX and provide step-by-step instructions to help you install and configure NSX. We also cover all the functional services of NSX, edge services gateway, service composer, and data security. In addition, we'll teach you to integrate partner solutions with NSX. Finally, we show you how to manage your NSX deployment and monitor NSX.
Style and approach
This is an easy-to-follow guide with tested configuration steps to get you up and running quickly. This book covers the nitty-gritty of installing, configuring, managing, and monitoring VMware NSX.

Preface
Networking is the most critical component of any IT architecture. Architects always want to lay the right foundations of networks and solve networking issues before the computation and storage is looked at. This is why I have always felt the need to have a better understanding of networking and how things work.
Network virtualization technology allowed me to have a behind-the-scenes, hands-on look at how networking works and the concepts that made it happen. The ability to deploy virtual appliances such as switches, load balancers, and routers and examine their functionality was very appealing. The pace at which I learned network virtualization (NSX) gave me the confidence to grow in a field in which I thought I lacked significant knowledge. Through my journey, I understood that network virtualization not only made me think like a network engineer, but also made me apply networking concepts very creatively to a virtualized environment, and this made it all the more appealing. What was complex before, now became extremely simple.
In 2015, I went about giving presentations at multiple VMUG UserCon sessions all around the country. My presentation was on Getting started with VMware NSX - Basics and Best Practices. Here, my aim was not to talk about what NSX can do but to talk about how easy it was to get started with NSX and also to squash some common misconceptions about it. I wasn't sure whether this was a topic worth talking about and wasn't expecting a large crowd. (My time slot to present was right after lunch, which wasn't very encouraging.)
Soon, I was proved wrong. In each and every city where I gave my presentations, all of my sessions had a full audience. People were eager to know how to get started with NSX and in fact, preferred this presentation to any of the other VMware NSX presentations happening at the same conference. I was able to quickly identify the huge knowledge gap and the plethora of common misconceptions about NSX and network virtualization, in general. I also observed that many of the attendees were network administrators with an interest in network virtualization.
This feedback from the tech community gave me a desire to write a book that covers the basics and teaches how to get started with NSX. I want to connect to the day-to-day administrator and the network engineer who is wondering how all the dots connect, and this is something I am passionate about. The book explains the basics and covers the deployment of the various features of network virtualization in simple and clear language and with screenshots that allow you to visualize the workflow as you read. I did have to work around a page restriction set by the publisher, so I focused on the most commonly used or sought-after features in the book even though I covered all of the NSX features and functionality. The audience feedback from various conferences helped me greatly.
I hope you enjoy working with this book and that it helps you to learn to use and understand NSX and network virtualization.
What this book covers
Chapter 1, An Introduction to Network Virtualization, gets you started with an introduction to network virtualization and an overview of its concepts. You will briefly learn about some of NSX's features and capabilities. We also have a NSX limits table to help you understand NSX's capabilities.
Chapter 2, NSX Core Components, talks about all the different components of NSX and how they all work together. You will also learn about VXLAN architecture that is the backbone of overlay or virtual networking. We will also briefly talk about transport zones that define the scope of a virtual network. You will learn about NSX Edge services and the distributed firewall as well.
Chapter 3, NSX Installation and Configuration, is where we will start deploying and configuring NSX. We will go over the installation process step by step and then configure our NSX deployment with a vCenter server. You will learn how to manage NSX using the vSphere web client and build your control and data planes.
Chapter 4, NSX Functional Services, discusses the deployment and configuration of different NSX services, such as logical switching, L2 bridging, and Edge gateway services. We will go over the configuration of transport zones and logical switching step by step. This will be an interesting chapter, where you will also learn the deployment of Edge appliances and set up L2 bridging, which allows you to extend a layer 2 network into NSX.
Chapter 5, Edge Services Gateway, discusses the NSX Edge gateway, which offers a lot of features and capabilities. We will go deeper into the services offered by the Edge gateway and look at how to deploy and configure them. We will look at how to configure routing and load balancing. You will also spend some time learning to set up DHCP and DNS services.
Chapter 6, Data Security, discusses one of the most important capabilities of NSX, its security, and also discusses the different NSX security offerings. We will discuss and learn how to set up security groups and configure them by mapping a security group to a specific policy. You will also learn briefly about the network extensibility feature of NSX.
Chapter 7, Monitoring, looks at how to enable monitoring for our environment using NSX. Activity monitoring is one of the features of NSX that is a boon for network and system administrators. You will learn how to configure it along with generating a virtual machine activity report. You will also learn about flow monitoring and Traceflow, which can simulate and allow you to test the network.
Chapter 8, Managing NSX, talks about NSX administrative tasks such as backup and restore and NSX Manager settings. We will revisit NSX Manager and explore all the different settings that can be set. We will look at setting up syslog, time, and DNS settings. We will also look at taking controller snapshots as well. We will also have a look at the setup of our NSX Manager with CA signed certificates along with configuring NSX with a domain.
Chapter 9, Conclusion, is the concluding chapter that includes important information and links
What you need for this book
Although you can dive right into this book, I recommend setting up a modest home lab of three servers running VMware's ESXi and vCenter. You are also encouraged to spend some time exploring the hands on labs offered for free by VMware. The specific NSX labs that will help you greatly are HOL-SDC-1603 and HOL-SDC-1625. These labs will help you get started with NSX without having to worry about the intricacies of having to set it up.
You can get to "hands on labs" by going to http://labs.hol.vmware.com and searching for the two labs I mentioned earlier.

An introduction to Network Virtualization
Today's datacenter demands have undergone a paradigm shift from what they were a decade ago. As the cloud consumption model is being rapidly adopted across the industry, the need for on-demand provisioning of compute, storage, and networking resources is greater than ever. One of the biggest contributing factors to enable the cloud consumption model isServer virtualization. Server virtualization has enabled fast consumption of compute resources along with add-on functionality and services. Snapshots, clones, and templates are all now easier than ever with Server virtualization.
