Tanzu Kubernetes Grid 1.3 Deployment with NSX ALB in VMC

Posted on by

Tanzu Kubernetes Grid 1.3 brought many enhancements with it and one of them was the support for NSX Advanced Load Balancer for load balancing the Kubernetes based workloads. TKG with NSX ALB is fully supported in VMC on AWS. In this post, I will talk about the deployment of TKG v1.3 in VMC. 

In this post, I will not cover the steps of NSX ALB deployment as I have already documented it here

Prerequisites

Before starting the TKG deployment in VMC, make sure you have met the following prerequisites:

  • SDDC is deployed in VMC and outbound access to vCenter is configured. 
  • Segments for NSX ALB (Mgmt & VIP) are created.
  • NSX ALB Controllers and Service Engines are deployed and controllers’ initial configuration is completed. 

Deployment Steps

Create Logical Segments & Configure DHCP

Create 2 DHCP enabled logical segments, (one for the TKG Management and one for the TKG Workload) in your SDDC by navigating to Networking & Security > Network > Segments.… Read More

vSphere with Tanzu Integration in VCD

Overview

Prior to v10.2, VMware Cloud Director supported K8 cluster deployment natively and integrated with ENT-PKS. With the release of v10.2, K8 integration is extended to vSphere with Tanzu. This integration enables Service Providers to create a self-service platform for Kubernetes Clusters that are backed by the vSphere 7.0 and NSX-T 3.0. By using Kubernetes with VMware Cloud Director, you can provide a multi-tenant Kubernetes service to your tenants.

In this article, I will walk through the steps of integrating vSphere with Tanzu with VCD. 

Pre-requisites for Tanzu Integration with VCD

Before using vSphere With Tanzu with VCD, you have to meet the following pre-requisites:

  • VMware Cloud Director appliance deployed & initial configuration completed. Please see VMware’s official documentation on how to install & configure VCD.
  • vCenter 7.0 (or later version) with an enabled vSphere with VMware Tanzu functionality added to VMware Cloud Director. This is done under Resources > Infrastructure Resources > vCenter Server Instances.

Global Load Balancing using NSX ALB in VMC

Overview

Global Server Load Balancing (GSLB) is the method of load balancing applications/workloads that are distributed globally (typically, multiple data centers and public clouds). GSLB enables efficient distribution of traffic across application servers that are dispersed geographically. 

In a production environment, the corporate name server delegates one or more subdomains to NSX ALB GSLB, which then owns these domains, and provides responses to DNS queries from clients. DNS based load balancing is implemented by creating DNS Virtual Service. 

How GSLB Works?

Let’s understand the working of GSLB using the below example. 

There are 2 SDDC’s running in VMC and both the SDDC has local load balancing configured to load balance set of web servers in their respective SDDC. The 2 Virtual Services (SDDC01-Web-VS & SDDC02-Web-VS) have a couple of web servers as pool members and the VIP of the Virtual Service is translating to Public IP via NAT.  

Let’s assume the 4 web servers running across 2 SDDC are servicing the same web application and you are looking for doing a global load balancing along with local load balancing. … Read More
