Chapter 11 — The Final Nanoservice Design ChecklistThis chapter is the gatekeeper. It exists to answer one question only: “Is this nanoservice correctly designed, or are we about to encode future problems?” If any item in this checklist cannot be answered confidently, implementation must stop. 1. ...Dec 12, 2025·4 min read
Chapter 10 — Designing for Mobile Without Letting Mobile Pollute Nanoservice DesignMobile clients are the fastest way to accidentally destroy a clean backend design. They bring: unreliable connectivity background execution limits push notifications retries and duplicates UX pressure for “real-time” behavior If nanoservices r...Dec 12, 2025·4 min read
Chapter 9 — Mapping Nanoservices to the Background Execution ModelAt this point, we have: clean nanoservice boundaries disciplined internal structure strict communication rules What remains is the most common place where systems collapse: Deciding what runs synchronously and what must be executed in the backg...Dec 12, 2025·4 min read
Chapter 8 — Nanoservice-to-Nanoservice Communication (OTP Style)Once nanoservices are defined and internally disciplined, the next danger is not boundaries — it is communication. In OTP systems, communication is cheap, fast, and tempting.That temptation must be controlled. This chapter defines how nanoservices ar...Dec 12, 2025·4 min read
Chapter 7 — Persistence Comes Last (And Why This Is Non-Negotiable)After defining domain logic correctly, the next temptation is immediate: “Let’s design the database now.” This temptation has destroyed more systems than bad algorithms ever have. In this architecture, persistence is deliberately the last concern, ...Dec 12, 2025·4 min read
Chapter 6 — Domain Logic: Where Business Rules Actually LiveAfter locking REST down as a thin entry point, we arrive at the most misunderstood part of backend systems: Where do business rules actually belong? Most systems answer this poorly.They scatter rules across controllers, services, database constrain...Dec 12, 2025·4 min read
