백엔드 커리큘럼 심화: Cell-Based Architecture로 Blast Radius를 통제하는 실무 플레이북
단일 대형 플랫폼을 작은 셀(cell) 단위로 나눠 장애 전파를 줄이고 복구 속도를 높이기 위한 설계·운영 기준을 숫자 기반으로 정리합니다.

Flash-MoE가 397B MoE 모델을 48GB MacBook에서 4.4 tok/s로 돌렸고, 바이브 코딩의 한계와 추상화의 가치가 재조명됐다. BitTorrent 창시자 Bram Cohen이 CRDT 기반 버전 관리 Manyana를 공개했고, Walmart은 ChatGPT 내 결제 전환율이 3배 낮다고 인정했다. GitHub의 가용성이 3나인도 위태롭고, POSSE와 Project Nomad가 웹 독립성 운동을 다시 불러왔다.

JavaScript 의존성 블로트의 세 기둥이 2026년에도 건재하고, GPT-5.2와 Claude Opus 4.6이 '무(無)'를 입력받으면 동일하게 침묵하는 현상이 발견됐다. Cloudflare가 archive.today를 C&C 봇넷으로 판정해 DNS를 차단했고, WebGPU+WASM 조합이 브라우저 영상 편집을 프로 수준으로 끌어올렸다. 3M의 PFAS 철수가 데이터센터 냉각 공급망에 충격파를 주고, C++26 contracts 최종 회의에서는 여전히 합의가 갈린다.
