0 - For API servers. I'm not sure if you could configure this with services like Elasticsearch.

Any requests sent directly to the servers simply wouldn't connect.
- ashtonkem 6y agoThat’s also a thing on Azure, but you can actually deploy certificates for mutual authentication as well. That way if somehow the network layer is pierced, you have another layer of protection.
