Explanation

Connecting directly over the instance private address within the same network and region keeps the path short and predictable which helps keep the 99th percentile latency under four milliseconds. This direct approach has no extra proxies and no cross region hops and it also minimizes operational overhead because there is nothing to deploy or manage between your clients and the managed Redis endpoint.
