0:00 Intro

3:00 Comparisons are almost always meaningless.

5:30 Scaling starts with well built software.

8:50 Eat healthy and exercise daily.

10:15 KISS, don’t be afraid, and boring better cool.

12:00 The bottleneck is almost always the database.

13:40 RDBMS works, almost always.

15:00 Everyone forgets to index.

17:30 Don’t use an RDBMS. What?

19:40 Networking/IO is really hard. Network as little as possible.

21:20 Connections are hard. Connect little, pool much.

25:00 Latency is THE metric.

26:10 The Internet is the Wild Wild West.

28:40 Caching is a silver bullet, almost.

29:00 Dumb caching is best caching.

29:40 Some application state may not be bad.

31:20 HTTP APIs can be E-Tagged (304) too.

34:12 Allocation is expensive.

37:40 Multi-threading and concurrency are necessary, but hard.

38:30 Some technologies are genuinely slow. Use fast technologies.

39:30 Scaling horizontally, vertically, and “enterprisely”.

40:30 Human impediment.

42:20 My Thoughts on Microservices
