It's fine, but you're going to attract a lot of network costs bridging data between AWS accounts.

Generally I'd stick to accounts per environment, you'll be worrying about a lot more when you get to FAANG scale.



Sharing a VPC between accounts with AWS RAM incurs no network costs between the accounts and greatly simplifies AWS networking. Additionally you can share and re-use security groups from the shared vpc across account boundaries.


Hey thank you! I didn't know that, I was still stuck in the thoughts of using Transit Gateways between accounts which of course attracts $$$.
