Overview of this book

VMware NSX is a platform for the software-defined data center. It 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. The book allows you a thorough understanding of implementing Software defined networks using VMware’s NSX. You will come across the best practices for installing and configuring NSX to setup your environment. Then you will get a brief overview of the NSX Core Components NSX’s basic architecture. Once you are familiar with everything, you will get to know how to deploy various NSX features. Furthermore, you will understand how to manage and monitor NSX and its associated services and features. In addition to this, you will also explore the best practices for NSX deployments. By the end of the book, you will be able to deploy Vmware NSX in your own environment with ease. This book can come handy if you are preparing for VMware NSX certification.

Logical switching

Logical switches have a similar functionality to physical switches—they permit the isolation of your applications and tenants for security and for other purposes. A logical switch creates a broadcast domain to allow the isolation of virtual machines. A logical switch is mapped to a unique VXLAN, which encapsulates the virtual machine traffic and carries it over the physical IP network.

Using logical switches, you can create VLANs in a similar way to a physical switch that spans large compute clusters. This now allows you to migrate your virtual machines using vMotion without any limitations of the physical network. This also allows you to have more control of your virtual network without having to alter or modify the physical network constructs. The logical switch is mapped to a VXLAN that encapsulates the traffic over the physical network. We discussed VXLAN and its packet architecture in Chapter 2NSX Core Components:
