Hey @0xlup3x ,

Boundary nodes serve the entire Internet Computer. According to [https://dashboard.internetcomputer.org/](https://dashboard.internetcomputer.org/), there are currently 12, but there is ongoing work on [decentralizing boundary nodes](https://forum.dfinity.org/t/long-term-r-d-boundary-nodes-proposal/9401/16).

I’m not sure if there’s a clear answer. Inter-canister calls aren’t limited by any boundary node limits obviously, but are limited by the actual execution of those calls. So one approach too scaling is to shard your application across subnets.
