he service IP of memcached. It is redirected to the client-side sidecar. The sidecar routes the connection to one of the memcached servers and copies the data between the two sockets &ndash; one connected to the app and another connected to memcached. And the same also occurs on the server side between the server-side sidecar and memcached. The role of proxy at that point is just boring shoveling of bits between the two sockets. However, it ends up adding substantial latency to the end-to-end connection.</p
