We would like to automate certificate renewal via Let’s Encrypt on NSX-T´s integrated load balancer (not the AVI load balancer). Is this even possible?
One other thing to note - VMware has indicated they plan to remove the NSX-T built-in load balancer in favor of NSX ALB (AVI). As a result, everything new should be done using NSX ALB. As dragance noted, all license levels of NSX Data Center that include load balancing (Advanced and above) also include licensing for NSX ALB. (See https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/products/nsx/vmware-nsx-datasheet.... and https://avinetworks.com/docs/latest/nsx-alb-basic-edition/ for more details.)
Note from NSX-T 3.2 release notes (https://docs.vmware.com/en/VMware-NSX/3.2/rn/vmware-nsxt-data-center-32-release-notes/index.html)
"Please be aware that VMware intends to remove support of the NSX-T Load Balancer in an upcoming NSX-T release, which will be generally available no sooner than one year from the date this message was announced (December 16, 2021)"
Note from NSX 4.1 release notes (https://docs.vmware.com/en/VMware-NSX/4.1.0/rn/vmware-nsx-410-release-notes/index.html)
VMware intends to deprecate the built-in NSX load balancer and recommends customers migrate to NSX Advanced Load Balancer (Avi) as soon as practical. VMware NSX Advanced Load Balancer (Avi) provides a superset of the NSX load balancing functionality and VMware recommends that you purchase VMware NSX Advanced Load Balancer (Avi) Enterprise to unlock enterprise grade load balancing, GSLB, advanced analytics, container ingress, application security and WAF.
We are giving advanced notice now to allow existing customers who use the built-in NSX load balancer time to migrate to NSX Advanced Load Balancer (Avi). Support for the built-in NSX load balancer for customers using NSX-T Data Center 3.x will remain for the duration of the NSX-T Data Center 3.x release series. Support for the built-in NSX load balancer for customers using NSX 4.x will remain for the duration of the NSX 4.x release series. Details for both are described in the VMware Product Lifecycle Matrix. We do not intend to provide support for the built-in NSX load balancer beyond the last NSX 4.x release.
