Cloud Functions

25. Why? Rapid development
NoOps (best server == no server)
Automatic scaling
Implicit availability
Supercharges microservices

26. Why
not? Unpredictable
Behavior could change while scaling
Resource leaks (really? without servers?)
Latency variations
High markup under load
Low utilization of compute resources
Expensive
100-200 ms latency for warm functions
2+ sec for cold functions
Slow
