| The following design introduces two components to the existing HA setup: | ||

||
| A queue that will replace websockets for communcation between `rollup-boost` <-> `reverse-proxy` The current approach has a single `websocket-proxy` that is a single point of failure. As the number of client connections increase, scaling up the networking/compute of the single instance also becomes a limitation. Without a message queue, each rollup-boost instance would also need to manage connections to many `reverse-proxy` as they may be scaled up/down. |

FYI you can run multiple websocket-proxy's connected to each rollup-boost instance. What we have is:
5 node HA sequencer cluster <-- N websocket proxy cluster <--- ALB
This has scaled up to a fairly large number of external clients, as each websocket proxy can handle quite a large number
