- 9. IPPON 2019 Abraham Wald Wald noted that the study only considered the aircraft that had survived their missions—the bombers that had been shot down were not present for the damage assessment. The holes in the returning aircraft, then, represented areas where a bomber could take damage and still return home safely. Wald proposed that the Navy instead reinforce the areas where the returning aircraft were unscathed, since those were the areas that, if hit, would cause the plane to be lost. source: https://en.wikipedia.org/wiki/Abraham_Wald

- 34. IPPON 2019 What is Serverless? ● No need to manage servers ● No need to even think about servers ● No need to provision infrastructure ● Pay only for what to use ● Use backend as a Service (BaaS) ● Deploy functions, not apps (FaaS) ● It’s event based/oriented Well… It means no servers right?
- 35. IPPON 2019 Drawbacks ➔ Loss of Server optimizations ➔ Implementation drawbacks: ● Execution duration ● Startup latency ● Tests ● Packaging / versioning
- 36. IPPON 2019 No access to underlying OS

IPPON 2019 Datadog SaaS product, created in 2010 by 2 French, started as an Infrastructure Monitoring Tool ● system / application / business metrics ● distributed tracing ● log management ● browser testing and synthetics ● full grown alerting engine on top of that A LOT of integrations, A LOT of opensource code
Editor's Notes
- The holes in the returning aircraft, then, represented areas where a bomber could take damage and still return home safely. Wald proposed that the Navy instead reinforce the areas where the returning aircraft were unscathed, since those were the areas that, if hit, would cause the plane to be lost.
