Hot take: overselling isn't a bug, it's a product decision nobody made on purpose.

Card payments solved this ages ago: authorize, capture later, auto-release if it times out. Inventory should too.

Reserve with a TTL or apologize at scale. Which does your team pick?

Does every mobile app need a backend? No.

Calculator → Runs locally
Chat app → Usually needs a backend
Offline-first app → Can use both

Architecture depends on requirements, not app size.

What's the backend? The hidden part of an app that does the real work — on servers you never see.

50% CPU: a login waits about 2× its work time.
90% CPU: 10×.
99% CPU: 100×.

Queues don't get slow slowly. They fall off a cliff.

What CPU target do you scale at?

Where does your app data go?

Into a database.

App → API → Backend → Database

PostgreSQL, MySQL & MongoDB help manage users, orders and more.

"Login is slow, let's lower the bcrypt cost."

That makes it faster for attackers too. The fix is more hashing capacity, not weaker hashes.

Which would you pick: more cores, or a separate hashing pool?

Hot take: retries without idempotency keys are just duplicate charges with extra steps.

Working on payment APIs at Visa made this stick: every write should be safe to replay. Most teams add it after their first incident.

What reliability pattern would you make mandatory?

Fail-closed or fail-open? Decide per side effect, then check what your cache already decided

Nobody chose fail-open.

19 MiB per argon2id hash: OWASP's minimum.

That's memory, not CPU. 1,000 logins hashing at once need about 18.6 GiB. Are your auth pods sized for that?
