The document provides tips for building distributed systems. Some key points include: - Start with two of everything to force solving scaling problems up front and need less overcapacity. - Separate processing from storage as they almost never scale together. - Scale out infrastructure rather than scaling up single systems to avoid issues. - Consider limits, failure handling, and what happens under full system capacity when designing distributed systems.

6. FAILURE
embrace it

7. SCALE
how hard can it be? let’s worry about that later.

8. KNOW YOUR LIMITS
who’s the largest customer you could sign?
what would happen if you did?

9. BALANCE
“customer” is a really bad shard key,
find something that distributes evenly & uniformly

10. SCALE OUT, NOT UP
bigger boxes aren’t going to save you
<

11. START WITH TWO
OF EVERYTHING
going from one to two is the hardest,
force yourself to solve the scaling problem up front

12. START WITH TWO
OF EVERYTHING
you’ll solve the scaling problem,
and need less overcapacity
THREE

13. LIMITS
we’ll probably never run out of memory

14. BACK PRESSURE
what happens when the system is working at full
capacity? what happens next?

15. PRODUCTION = QA
production is where the weird shit happens,
can you test production traffic without
deploying to production?
=

16. MONOLITHS
running all the things on the same box is really fast.
what could ever go wrong?

17. DECOUPLE
UNTIL IT BREAKS
moving things to separate services means that you
will be able to scale them independently

18. PROCESSING
& STORAGE
separate processing from storage,
they almost never scale together.

19. SCALE
exponential scaling is also scaling,
but you want it as cheaply as possible

20. SCALE
your CFO may not agree that O(2n) = O(n)
