Object storage

What belongs in object storage

• Deployment bundles and exported snapshots
• Diagnostic captures and logs that are too large for transactional stores
• Immutable artifacts tied to a version identifier

Design constraints

• Immutable artifacts support reproducible deployments and audits
• Retention must match incident and compliance needs
• Artifacts must be traceable back to version IDs

Architecture at a glance

• Define a stable artifact boundary (what you deploy) and a stable signal boundary (what you observe)
• Treat changes as versioned, testable, rollbackable units
• Use health + telemetry gates to scale safely

Typical workflow

• Define scope and success criteria (what should change, what must stay stable)
• Create or update a snapshot, then validate against a canary environment/site
• Deploy progressively with health/telemetry gates and explicit rollback criteria
• Confirm acceptance tests and operational dashboards before expanding

System boundary

Treat Object storage as a repeatable interface between engineering intent (design) and runtime reality (deployments + signals). Keep site-specific details configurable so the same design scales across sites.

Example artifact

topic: Object storage
plan: define -> snapshot -> canary -> expand
signals: health + telemetry + events tied to version
rollback: select known-good snapshot

Engineering outcomes

• Immutable artifacts support reproducible deployments and audits
• Retention must match incident and compliance needs
• Artifacts must be traceable back to version IDs

Quick acceptance checks

• Store snapshots/bundles as immutable artifacts with stable naming
• Keep retention policies aligned with audit/incident needs

Common failure modes

• Drift between desired and actual running configuration
• Changes without clear rollback criteria
• Insufficient monitoring for acceptance after rollout

Acceptance tests

• Verify the deployed snapshot/version matches intent (no drift)
• Run a canary validation: behavior, health, and telemetry align with expectations
• Verify rollback works and restores known-good behavior

Failure modes

• Missing/expired artifacts that break reproducibility
• Inconsistent naming/versioning that makes artifacts hard to trace
• Permissions misconfiguration that blocks edge downloads/uploads

Implementation checklist

• Store snapshots/bundles as immutable artifacts with stable naming
• Keep retention policies aligned with audit/incident needs
• Validate permissions for edge download/upload flows
• Ensure artifacts are traceable back to snapshot/version IDs

Rollout guidance

• Start with a canary site that matches real conditions
• Use health + telemetry gates; stop expansion on regressions
• Keep rollback to a known-good snapshot fast and rehearsed

Acceptance tests

• Verify the deployed snapshot/version matches intent (no drift)
• Run a canary validation: behavior, health, and telemetry align with expectations
• Verify rollback works and restores known-good behavior
