Take a look at Proxmox SDN features: https://pve.proxmox.com/pve-docs/chapter-pvesdn.html (some of it is still in beta, I think).

I think it comes pretty close - close enough for probably most but the very largest of users, who, I think, should probably have tried to become hyperscalers themselves, instead of betting the farm and all the land around it on VMware (by Broadcom).

the thing it is mainly missing is multi-tenancy self service. (ipam integration seems very nice though).

NSX allows you to create seperate clusters which hosts VM's which run the routing and firewalling functionality.
