    (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

  23. GET /timeline edge-lb sched api-server auth.Auth cache.Get mysql.Query user.Profile cache.Get

    mysql.Query images.Filter blobstore.Get

  24. bare metal kernel process scheduler network stack cloud stack user

    process frameworks your code

  25. GET /timeline edge-lb sched api-server auth.Auth cache.Get mysql.Query user.Profile cache.Get

    mysql.Query images.Filter blobstore.Get not my fault

    cache.Get mysql.Query blob.Get where is the source code?

  27. GET /timeline auth.Auth cache.Get mysql.Query user.Profile cache.Get mysql.Query images.Filter blobstore.Get

    cache.Get mysql.Query blob.Get who to call?

  28. GET /timeline auth.Auth cache.Get mysql.Query user.Profile cache.Get mysql.Query images.Filter blobstore.Get
