Yes I came here to talk about bandwidth too, which is not mentioned in the article at all but can be the biggest engineering cost focus depending on app/scale :-). Over 10tb of transfer you can (and should) negotiate some cheaper pre-committed pricing on bandwidth.

There’s also engineering around the network involved in your application. A lot of architectures internally reflect traffic around (moreso if you’re also accepting some ridiculous amount of traffic rather than just serving it). In those cases you can save a lot of money by figuring out ways to pass traffic through unmetered connections like internal albs and amazon hosted dbs. Otherwise you can either rack up a lot of cross-az traffic charges or be on the hook for engineering your way to minimize those costs.
