SRE We connect dots when distributed system fails • IMOC • Investigate on the “seams” of running system • Collaborate / communicate to drive resolution on “cracks” 分散システムの失敗パターンに対するエキスパート Photo purchased from iStock

Multiplication brings value App dev and SRE • Brings the high velocity project scoping • Distributed system 101 Core API dev and App dev • User and Maker feedback Core API dev and SRE • High-level overview v.s. investing on your core interests

We are all one team Growth brings specialization and operational e ciency Imagine the dysfunctional feedback loop: • Highly scalable system without the user growth • Growing features without resiliency toolkit • Exponential domain onboarding cost without simple interface to Core API ffi Photo by Kier In Sight on Unsplash

Chaos Engineer your org Hybrid (bridging) developer can disrupt specialization • Early adaption is quicker and better than an afterthought • It's easily adaptable, since the underlying failure is common across multiple applications • Usually IC has appetite for resiliency toolkits More bridging developers leads to organic early planning: a key to both speed and quality Photo by Olivier Guillard on Unsplash
