... while quite a few understand the fundamentals of infrastructure they consume, and end up in undesirable places (with major impact on performance, costs, or a combination of both). I fairly recently worked for a few months in a web3/blockchain/NFT/<other buzzwords>/crypto-wallet company, and the fact that I had to explain in ELI5 mode how diff types of databases (and how critical such a choice is), name resolution (a.k.a. DNS), global vs local load balancers of different types work, which measurements and logs to enable, and where, reality of redundancy and recovery times, on prem(NO - you cannot rely on moving VMs over L2 connected DCs!) and in the cloud, etc., to "app" (whatever end) folks, with no understanding how these fundamental services [kept] impact[ing] their clients, was an experience I would certainly not remember too dearly. Even a comprehensive explanation of email client headers reading, to an office full of FE and BE engineers, who failed our security tests (joyfully clicked on anything having a link, in a message, 'cause it was presented as an "API PoC"), was revealing in regards to the missing basics. /rant
