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.

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
