Getting Started With NSX ALB: Part-4-Load Balancer in Action

In the last post of this series, I completed NSX-T integration with NSX ALB. Now it’s time to test the load balancer. 

If you have missed the earlier post of this series, you can read them from the below links:

1: NSX ALB Introduction & Architecture

2: Avi Controller Deployment & Configuration

3: NSX ALB Integration With NSX-T

Let’s get started.

Before I dive into the lab, let me first explain the topology that I have implemented in my lab.

  • I have two of my web servers sitting on the Web-LS logical segment backed by subnet 192.40.40.0/24.
  • Logical segments ALB-Mgmt-LS and ALB-Data-LS are connected to the same Tier-1 gateway to which Web-LS segment is connected and are backed by subnets 192.20.20.0/24 and 192.30.30.0/24.
  • Avi Service Engine VM’s are connected to both Mgmt & Data LS
  • All 3 segments are created in the overlay transport zone. 
  • My Tier-0 gateway is BGP peering with a physical router and my Win JB machine is able to ping the logical segments default gateway.

Getting Started With NSX ALB: Part-3-NSX-T Integration

manish_jha86

In the previous post of this series, I discussed Avi controller deployment and basic configuration. It’s time to integrate NSX-T with NSX ALB. High-level steps of NSX-T integration can be summarized as below:

  • Create a Content Library in vCenter
  • Deploy a Tier-1 gateway for Avi Management.
  • Create Logical Segments in NSX-T for Avi SE VM’s.
  • Create credentials for NSX-T and vCenter in Avi.
  • Register NSX-T with Avi Controller.
  • Create an IPAM profile. 

Let’s get started.

Create a Content Library in vCenter

Deployment of Avi Service Engine VM’s is done automatically by Avi Controller when we create Virtual Service. For this to work, an empty content library needs to be created in vCenter server as the controller pushes Avi SE ova into the content library and then deploys the SE VM’s. 

Deploy Tier-1 gateway for Avi Management

You can use the existing Tier-1 gateway or can deploy a new one (dedicated) for Avi management.… Read More

Getting Started With NSX ALB: Part-2- Avi Controller Deployment & Configuration

manish_jha86

The first post of this series talked about NSX ALB ad its architecture. Also, I discussed features that make NSX ALB unique. In this post, I will discuss deployment and basic configuration and later I will discuss ALB integration with NSX-T.

The official process of NSX ALB deployment is documented Here & cluster creation process Here

Hardware requirements for Avi Controllers and Service Engine VM’s are documented here

Prerequisites for NSX ALB Deployment:

  • vSphere is deployed and configured.
  • NSX-T Manager is deployed and is integrated with vCenter.T0-GW is deployed, and is paired with the physical Network using BGP.

NSX-ALB Controller OVA can be downloaded from https://customerportal.avinetworks.com

Ova deployment is straight forward and I am not covering the deployment wizard. Make sure to leave the Sysadmin login authentication key field blank when deploying controller ova. 

Once Controller VM boots up, connect to the web interface of the controller by typing https://<Avi-Controller-ip>/

Configure the controller administrator account by setting up password and email id (for password reset in case of account lockout)

Configure DNS and NTP server information.… Read More

NSX Advanced Load Balancer (Formerly Avi Vantage) is a multi-cloud Software Defined Load Balancer which provides scalable application delivery across any infrastructure. NSX ALB is 100% software-defined and provides:

  • Multi-cloud: Consistent experience across on-premises and cloud environments through central management and orchestration.
  • Intelligence: Built-in analytics drive actionable insights that make autoscaling seamless, automation intelligent and decision making easy.
  • Automation: 100% RESTful APIs enable self-service provisioning and integration into the CI/CD pipeline for application delivery.

Note: NSX ALB solution came through VMware acquisition of Avi Networks in 2019.

Some of the key features of NSX ALB are:

  • Autoscaling of Load Balancers and Applications.
  • Web Application Analytics & Performance Insights.
  • Automation for IT, Self-Service for Developers.

To know more about these features, please visit Avi Networks website. 

NSX ALB Architecture

NSX-ALB Consists of two main components,

  • Avi Controller.
  • Service Engines (SE).

Controllers are deployed by platform administrator and Service Engines are automatically deployed by the controller when we create Virtual Services.… Read More
