VMware NSX-T

Introduction

VMware NSX-T™ Data Center provides an agile software-defined infrastructure to build cloud-native application environments. NSX-T Data Center focuses on providing networking, security, automation, and operational simplicity for emerging application frameworks and architectures that have heterogeneous endpoint environments and technology stacks.

VMware NSX

VMware NSX is a network virtualization and security platform that enables the virtual cloud network, a software-defined approach to networking that extends across data centers, clouds and application frameworks.

VMware NSX is suitable for all infrastructure types:

• Multi-cloud environments
• On-premises data centers
• Bare metal servers
• Containerized workloads

Benefits of NSX-T

The main benefit is that NSX-T can be deployed in heterogeneous environments with many different components. NSX-T is not under the confines of the vCenter deployment. You can have multiple vCenter servers and use one NSX manager as a single pane of glass for controlling your virtual network. Or, you do not have to deploy a vCenter at all. Instead, you can choose ESXi as the operating system in the NSX-T GUI.

NSX-T Main Components:

The primary components of VMware NSX-T are:

• NSX-T Manager: provides graphical user interface (GUI) and RESTful API for creating, configuring, and monitoring NSX-T components, such as segments and gateways.

• NSX-T Controller: they are responsible for the programmatic deployment of virtual networks across the entire NSX-T architecture, and control the virtual networks and overlay transport tunnels.

• NSX-T Edges: provides routing services and connectivity to networks that are external to the NSX-T deployment.

• Logical Firewall: NSX-T handles traffic in and out of the network according to firewall rules.

• Logical Routers (Gateways): NSX-T Gateways provide North-South connectivity so that workloads can access external networks and East-West connectivity between different logical networks.

• Transport Zone: A transport zone defines a collection of hosts that can communicate with each other across a physical network infrastructure.

Supported Target Versions

• Application validated against target versions 3.2.0 and 4.0.0
• REST API version using 3.2.0
• REST API version 4.0.0
