Lately, I’ve been spending a lot of time getting our company lab set up and configured with all the bells and whistles that VCF 9 brings to the table. The new SSO experience was something I was really looking forward to. Previously, you had to configure the identity provider for every single product and platform, then add in the permissions and then manage that connection seperately. The new SSO experience, powered by the all new Identity Broker, is supposed to alleviate a lot of that management overhead.

Previously, administrators used the SDDC Manager GUI to provision a new WLD. In VCF 9, this process now happens exclusively through VCF OPS, offering more flexibility, automation, and integration with moder
