"#ad System Design: Chat App Within one service you generally only need one compute resource ie EC2 Lambda Fargate etc. Multiple usually just adds additional complexity. That said this isnt the only problem with the initial design so Ill leave it to you folks to point out the rest.

"System Design: Ticketmaster This is a cool problem as you need to preemptively scale up architecture before big releases.
