NSX Advanced Load Balancer Integration

NSX Advanced Load Balancer (ALB), formerly known as Avi Vantage, is VMware’s load balancer solution. It can provide ubiquitous, high-performance load balancing functionality for pod networking (L4 load balancer and ingress), and node networking in the Kubernetes cluster through deploying AKO (Avi Kubernetes Operator) in a cluster. By interacting with Avi Controller, it can provide traffic observability, network security, high configurable load balancer data plane and other advance features. For more information on the services provided by NSX ALB, see Avi with Cloud Services.

Tanzu Kubernetes Grid - NSX Advanced Load Balancer integration provides you the easiest solution to completely leverage the features of the NSX Advanced Load Balancer in an enterprise level multi-Kubernetes clusters scenario.

The integrated solution helps implement:

  • L4 Load Balancer Implementation
  • L7 ingress controller
  • Cluster endpoint VIP and control plane load balancing provider
  • IPv4/IPv6 dual-stack networking

This is achieved by running an Avi Kubernetes Operator (AKO) on each cluster. When compared with the AKO that is installed directly through the Helm CLI, the AKO managed by Tanzu Kubernetes Grid has huge advantages and unique and powerful functionalities, as described in the following table:

AKO managed by Tanzu Kubernetes Grid AKO installed using the Helm chart
AKO configurations and Functionalities (AKO CRDs) Yes
Yes
AKO Lifecycle (Deploy/Upgrade/Deletion) Management Yes
Manual
AKO Credentials and Certificate Management Yes
Manual
Avi Resource Lifecycle Management Yes

IPv4/IPv6 dual-stack networking Yes No

Tanzu Kubernetes Grid includes VMware NSX Advanced Load Balancer Essentials Edition.

To install NSX ALB for Tanzu Kubernetes Grid on VMware Cloud on AWS, Azure VMware Solution, or Google Cloud VMware Engine, see Install NSX Advanced Load Balancer in a VMware Cloud Environment.

NSX Advanced Load Balancer Features in Tanzu Kubernetes Grid

You can configure NSX Advanced Load Balancer in Tanzu Kubernetes Grid as the:

All the functionalities are achieved by running AKO in the Kubernetes cluster, which interacts with NSX Advanced Load Balancer. For more information on AKO, see Avi Kubernetes Operator.

Dual-Stack Support

For information about how to implement dual-stack networking for both of the NSX ALB load balancer and ingress services, see IPv4/IPv6 Dual Stack Networking.
