Consul service-mesh gateways value add: The when and why

Hi, we’re still coming to grips with Consul and trying to wrap our heads around the various tradeoffs… we’re stumped on when and why of the the Consul service-mesh gateway.

We’ll have a multiple datacenter setup. The instances in each data center are fully routable to each other. Everything is encrypted over wireguard.

Is there any value added from having a Consul service-mesh gateway setup in such a scenario?

By value we have in mind the topics: a) functionality b) performance c) maintenance

Appreciate any insights, hints or tips.

Kind regards
