VMware NSX
VMware intends to deprecate the built-in NSX load balancer and recommends customers migrate to NSX Advanced Load Balancer (Avi) as soon as practical.
As per the NSX 4.1.2.0 release notes, the 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 are described in the Broadcom Product Lifecycle Matrix. Broadcom does not intend to provide support for the built-in NSX load balancer beyond the last NSX 4.x release.
