VMware Cloud Foundation (VCF) 9.0 continues to support one of the most popular and powerful load balancer, VMware Avi Load Balancer. When you deploy a new VMware Avi Load Balancer within a given VCF Domain, by default SDDC Manager will deploy three VMware Avi Controllers for high availability purposes.
For lab purposes, you may not need all three VMware Avi Controllers but there was no way to change the system default in earlier releases of VCF. With VCF 9.0, we now have way to deploy just a single VMware Avi Controller, which is fantastic for lab and testing purposes.
UPDATE (05/27/26) - This workaround is still applicable for VCF 9.1.0, there is variable called $vcf91 which is set to $true which will add an additional property that is required with VCF 9.1 and later deployments.
Disclaimer: This is not officially supported by Broadcom, use only within a lab environment.
