services̶ones that never fail. It turns out that past a certain point, however, increasing reliability is worse for a service (and its users) rather than better! Extreme reliability comes at a cost: maximizing stability limits how fast new features can be developed and how quickly products can be delivered to users, and dramatically increases their cost, which in turn reduces the numbers of features a team can afford to offer. Further, users typically donʼt notice the difference between high reliability and extreme reliability in a service, because the user experience is dominated by less reliable components like the cellular network or the device they are working with. Put simply, a user on a 99% reliable smartphone cannot tell the difference between 99.99% and 99.999% service reliability! With this in mind, rather than simply maximizing uptime, Site Reliability Engineering seeks to balance the risk of unavailability with the goals of rapid innovation and efficient service operations, so that usersʼ overall happiness̶with features, service, and performance̶is optimized. 100% Reliability Is Rarely the Right Answer 9 Ref: https://sre.google/sre-book/embracing-risk/

supporting all Nulab services • Handles sensitive org/user data • Auth, Billing, and Security-hardening features Critical Systems Solo SRE The Burden of Return • Sunset of a primary product • New tech stack & lack of domain knowledge • Juggling childcare and housework • Moved to a team of 1 after 3 departures • Getting by with help from kind neighboring teams (Platform, other SREs, Developers, etc.)
Datadog CSM ) 🔄 15 Trial is available! Maybe just a little... Wow, Bits is impressive! Too busy to touch it I need more SREs! Bits AI SRE! Experiencing AIOps thru a 30-day trial and a strong nudge Rising AIOps
that aren't urgent but can't be ignored 20 App not deploying A few 5xx errors Help! Too many slow queries Internal tools inaccessible Pod restarting repeatedly It just broke suddenly High CPU usage, huh? Feels slow, doesn't it? Often impossible to start immediately and ties up multiple people
finish with just Bits now I don't even open AWS Console or Terminal anymore Futahashi-san is impressive! A world I never would have believed a year ago That's insane
trigger an investigation. • APM latency alerts lack the ability to provide additional context. • Invisible issues remain uninvestigable if they aren't caught by monitors or APM latency. • Unsupported data sources cannot be utilized for investigations. But is Bits in its current state enough? 26 We must lower the barrier to entry and expand coverage for Bits
and Adoption of Bits Higher Expectations for "Bits AI SRE" While "Bits AI SRE" is highly effective even without tuning, I expect it to achieve even greater results with less effort in the future. Specifically, it currently requires pre-configured monitors as investigation triggers, and context must be added to those monitors to gain deeper insights. In the future, I hope it will be able to autonomously recognize anomalies and leverage context based on all available information within Datadog. 27 Ref: https://www.datadoghq.com/ja/blog/datadog-live-tokyo-2025-recap/
