meanwhile. Does it really take that long for such an instance to be set up?

Some checks are probably not completed yet. I haven’t used it myself but looking at timeouts I expect it to be slow https://github.com/terraform-providers/terraform-provider-azurerm/blob/1075cfa6204836bef09d9dc3312b80ada67043d1/azurerm/internal/services/redis/resource_arm_redis_cache.go#L42

Indeed. Pulumi just finished. 😉
