Overview of this book

This book begins with a brief introduction to VMware's NSX for vSphere Network Virtualization solutions and how to deploy and configure NSX components and features such as Logical Switching, Logical Routing, layer 2 bridging and the Edge Services Gateway. Moving on to security, the book shows you how to enable micro-segmentation through NSX Distributed Firewall and Identity Firewall and how to do service insertion via network and guest introspection. After covering all the feature configurations for single-site deployment, the focus then shifts to multi-site setups using Cross-vCenter NSX. Next, the book covers management, backing up and restoring, upgrading, and monitoring using built-in NSX features such as Flow Monitoring, Traceflow, Application Rule Manager, and Endpoint Monitoring. Towards the end, you will explore how to leverage VMware NSX REST API using various tools from Python to VMware vRealize Orchestrator.

Introduction


Network virtualization with VMware NSX will create a overlay virtual network based on VXLAN. Connection from the VXLAN overlay network to the outside world will be via a router; in NSX, the router is NSX Edge Gateway. In some cases, physical servers or appliances need to reside in the same layer 2 network as the virtual machines. To allow these non-virtualized workloads to communicate in the same layer 2 network with the virtualized workloads layer, layer 2 bridging must be used.

Layer 2 bridging allows virtual machines in logical switches to have direct layer 2 access to the physical network. The following are some typical layer 2 bridging use cases:

  • Physical-to-virtual and virtual-to-virtual migrations from VLAN to VXLAN where changing IP addresses is not an option:
  • Extending physical network services (such as load balancing, firewall, storage) to virtual machines in logical switches:
  • Extending virtual services in logical switches to external physical devices layer 2 bridging...
