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.

Transport zones

We have briefly looked at transport zones in the previous chapters. A transport zone controls the domain of a logical switch among the hosts. In other words, it controls which hosts a logical switch can reach. A transport zone is configured on a per-cluster basis and can span multiple clusters in a vCenter. A universal transport zone can span multiple clusters across multiple vCenters. A transport zone dictates which host and, by extension, which virtual machines are allowed to participate in a particular network. In a typical environment, there can be more than one transport zone that is mapped to a host or to a cluster. However, a logical switch can only belong to one transport zone.

If a virtual machine belongs to a different transport zone, you will not be able to directly communicate with that virtual machine. This means that a vNIC is limited to spanning within the bounds of a transport zone. A virtual machine, however, can have multiple vNICs, each belonging to a different...
