    (disks) load balancer critical path

  19. cpdd (critical path driven development)

  20. discover the critical paths make them reliable and fast make

    them debuggable

  21. how do we get there? events or tracing

  34. instrumentation is expensive CPDD CHALLENGE #4:

  35. dynamic capabilities are underestimated CPDD CHALLENGE #5:
