Pattern deep dives
Start with the architecture, not the abstraction.
Clear explainers for API gateways, sagas, outbox patterns, idempotency, service discovery, observability, and the choices around them.
Membership for backend builders
Systems design, made executable.
microservices.fyi turns distributed-systems knowledge into decision kits, prompt packs, operational checklists, and AI-assisted workflows your team can actually use.
Built for senior backend engineers, staff engineers, architects, and engineering leaders.
Every topic ships with utility
Explanation → trade-off → prompt → checklist → related concepts
The standard we are building toward
Useful before it is impressive.
Human-reviewed publishing
Nothing auto-publishes. AI drafts, contributed work, and sourced pieces all pass a human accuracy and tone review.
Trade-offs in the open
Every pattern is framed around when to use it, when not to, and the failure modes that shape the decision.
Freshness you can inspect
Execution assets carry model, framework, and verification context so you can judge what still applies.
From reading to doing
A reference library for decisions that cannot stay theoretical.
Follow a topic from its core pattern to the tools, questions, and guardrails needed to put it into practice.
Prompt Library
Prompts with expected outputs and guardrails.
Use structured prompts to investigate designs, review assumptions, and turn architecture work into repeatable engineering workflows.
Decision Kits & AI Loops
Move from a trade-off to an accountable next step.
Compare options, run readiness checks, surface risks, and use step-by-step loops designed for real backend teams.
Operational lens
Failure modes belong beside the pattern.
Recognize symptoms before an incident becomes a postmortem.
Trace likely causes, signals to watch, and mitigations to prepare.
Follow related concepts across the library without losing the thread.
Build with better context
Make the next architecture decision easier to defend.
Join microservices.fyi for practical patterns, grounded trade-offs, and execution assets designed to keep moving after the meeting ends.
