Classic AWS. I have a SA Pro cert and I still couldn't reliably articulate the difference between Lightsail, SAM, and Amplify CLI. It feels like they keep adding to each without any apparent strategy. I didn't even know there was another product also branded "Amplify" separate from the CLI.
AWS really needs more centralized decision-making. It feels like individual product teams are allowed to go way off in the weeds without any frame of reference for whether their solutions make sense when plugged into the full suite.
