A condensed summary of the 25 most important enterprise delivery practices for Rust engineering teams - drawn from every page in this section.
Separate PR and release pipelines: PR proves code; release promotes immutable image SHA - Release Management.
Tag images with git SHA: Never deploy floating tags to production.
Expand-contract migrations: Backward-compatible schema steps enable rollback - Rollback Strategies.
Migration before traffic shift: Run sqlx migrate in release job before canary weight increases.
Document API to worker deploy order: Per service in repo docs/deploy-order.md.
Pause workers on incompatible schema steps: Avoid poison queue messages.
Staging mirrors prod pool sizes: Catch sqlx pool exhaustion pre-prod - Environments & Config Promotion.
Smoke test write and read path: /health/ready alone is insufficient.
Feature flags default off: Server-side evaluation - Feature Flags & Progressive Delivery.
Kill switches in runbooks: Flag off before image rollback when path is isolated.
Sunset flags after 30 days stable: Stale flags are regression debt.
Canary at 5-10% first: Soak 10+ minutes with p95 guardrails.
Guardrail queue depth and pool wait: Not only HTTP 5xx rate.
Auto-abort canary on SLO burn: Wire analysis to rollout controller.
Blue-green keeps warm rollback: Fast swap when canary skipped.
Annotate dashboards with deploy SHA: Correlate incidents in minutes.
Track DORA per service: Frequency, lead time, CFR, MTTR - DORA Metrics.
Tag incidents with deploy SHA: Accurate change failure rate.
Tie deploy speed to error budget: Freeze features when budget low.
Release notes include migration and rollback: Support reads #releases Slack.
CONCURRENTLY indexes on large Postgres tables: Avoid migration locks.
Retain 10 prod image tags: rollout undo requires history.
API and worker same Cargo.lock hash: Runtime skew causes subtle bugs.
Pre-register A/B experiments: Guardrails abort harmful variants - A/B Testing & Experimentation.
Game day rollback quarterly: DORA MTTR is a practiced skill.
Elite teams deploy daily with strong CI; weekly train is fine if CFR and MTTR are healthy.
cargo test, clippy -D warnings, cargo audit, integration tests, migration dry-run on staging.
Single release train coordinates API + worker SHA; document in monorepo README.
Hotfix with identical artifact tested in staging + flag kill switch ready; document exception.
sccache, crate splitting, and CI parallelism are delivery investments.
Separate pipeline from server; same semver discipline and SBOM attachment.
Never point staging at prod DB; anonymized snapshots only.
Service tech lead; review on every schema epic.
Commerce peaks + year-end; security CVE exceptions with EM approval.
Pick one DORA metric per quarter; tie to concrete practice from this list.
