Infrastructure

Definition

Infrastructure coverage in this archive spans 41 posts from Feb 2016 to Mar 2026 and focuses on reliability, delivery speed, and cost discipline as one system, not three separate concerns. The strongest adjacent threads are devops, cloud, and kubernetes. Recurring title motifs include kubernetes, infrastructure, production, and need.

Working claims

  • Most posts prioritize predictable operations over feature breadth or stack novelty.
  • Early posts lean on production and kubernetes, while newer posts lean on infrastructure and engineering as constraints shifted.
  • This topic repeatedly intersects with devops, cloud, and kubernetes, so design choices here rarely stand alone.

How to apply this

  • Set SLOs first, then choose tooling that keeps deploy, observability, and rollback simple.
  • Start with the newest post to calibrate current constraints, then backtrack to older entries for first principles.
  • When boundary questions appear, cross-read devops and cloud before committing implementation details.

Where teams get burned

  • Adding platform layers faster than the team can operate and debug them.
  • Chasing throughput gains without proving they improve end-user reliability.
  • Applying guidance from 2016 to 2026 without revisiting assumptions as context changed.

    The 2026 AI Build vs. Buy Calculus (It’s Just Operational Cost) · 3 min By mid-2026, AI build vs buy has nothing to do with novelty.
