The document discusses the evolution from less complex to highly distributed computing architectures, highlighting the challenges of debugging and maintaining system reliability in modern SaaS environments. It emphasizes user expectations for immediate data processing and high availability, alongside the difficulties posed by complex asynchronous systems. The authors propose solutions and strategies for developing in production environments to enhance responsiveness in data handling.

- 2. Who are we? Brian Clapper CTO of Circonus Whipping boy of the modern SaaS stack. Theo Schlossnagle CEO of Circonus Repeat denier of reality. Tuesday, October 2, 12
- 3. How the world used to look (less xtreme) Architectures driven by user interaction: (e.g. web page load ➠ web page response) Tuesday, October 2, 12
- 4. How the world used to look (less xtreme) isolated user A’s page load doesn’t effect user B. latent user A’s affect shows up “later” in user B’s view. Tuesday, October 2, 12
- 5. How the world used to look (less xtreme) Problem reproducibility is achievable (even if sometimes painful) Tuesday, October 2, 12
- 6. How the world looks now (more xtreme) Architectures driven by high volume data and users Tuesday, October 2, 12
- 7. How the world looks now (more xtreme) every piece of data entering the architecture can effect a user’s subsequent experience. Tuesday, October 2, 12
- 8. How the world looks now (more xtreme) sometimes the data must effect a user’s subsequent experience. Tuesday, October 2, 12
- 9. How the world looks now (more xtreme) Social systems cause indirect impact via user action eroding isolation. Tuesday, October 2, 12
- 10. How the world looks now (more xtreme) A more responsive web is eroding users’ acceptance of latent state. Tuesday, October 2, 12
- 11. How the world looks now (more xtreme) Highly distributed systems (due to complexity and scalability) means no single world state Tuesday, October 2, 12
- 12. How the world looks now (more xtreme) Highly distributed systems (due to complexity and scalability) means difficult repeatability of state and failures Tuesday, October 2, 12
- 13. How the world looks now (more xtreme) Highly distributed systems (due to complexity and scalability) means treacherous debugability Tuesday, October 2, 12
- 14. Despair all ye’ who debug here I studied distributed systems long enough to understand “the suck” you do not wish to have in your lives. Tuesday, October 2, 12
- 15. Despair all ye’ who debug here Expedient debugging requires a quick realization of a precipitating state of failure. Tuesday, October 2, 12
- 16. Despair all ye’ who debug here In distributed systems, post-mortem techniques are less useful because recreating possible global state is a mind-bending (or brain-damaging) exercise. Tuesday, October 2, 12
- 17. Despair all ye’ who debug here Applying older techniques to small controlled distributed systems is still feasible, but complex, asynchronous architectures can be nearly impossible. Tuesday, October 2, 12

- 20. How we see the world today High velocity non-user-generated data inflow. Tuesday, October 2, 12
- 21. How we see the world today Users expect sub-second reflection of all input data and drawn-conclusions. Tuesday, October 2, 12
- 22. How we see the world today Users expect extremely high availability (100%, you can only disappoint) Tuesday, October 2, 12
- 23. How we see the world today I was surprised how impatient and demanding users are... until I used the tool... and felt exactly the same way. Tuesday, October 2, 12
