Learning VMware NSX - Second Edition

By: Ranjit Singh Thakurratan

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.

NSX controller clusters

NSX controller provides a control plane functionality to distribute logical routing and VXLAN network information to the underlying hypervisor. Controllers are deployed as virtual appliances and should be deployed in the same vCenter NSX manager is connected to. In a production environment it is recommended to deploy a minimum of three controllers. For better availability and scalability we need to ensure DRS ant-affinity rules are configured to deploy controllers on a separate ESXI host. Control plane to management and data plane traffic is secured by certificate-based authentication.

It is important to note that controller nodes employ a scale-out mechanism where by each controller node uses a slicing mechanism that divides the workload equally across all the nodes. This renders all controller nodes active at all times. If one controller node fails then the other nodes are reassigned the tasks that were owned by the failed node to ensure operational status.
