Is the Release Strategy Defined and Aligned With Change Impact?

Type: Structure
Category: Release
Audience: Tech leads, backend leads, SREs, and PMs planning production deployment

🔍 What This Perspective Covers

Release is not deployment.
It is a negotiation with failure.

Even small changes can cause large damage if release strategy is not considered—
especially under multi-tenant, distributed, or asynchronous conditions.

⚠️ Common Failure Patterns

  • All-or-nothing deploy with no rollback path
  • Feature exposure tied directly to deploy, no toggles or controls
  • DB schema changes without forward/backward compatibility
  • Downtime assumed as “unavoidable” due to monolithic migration
  • Release timing misaligned with business risk window (e.g. peak hours)

✅ Typical Use Cases

  • Canary rollout to 5% tenants before global rollout
  • Feature toggle to decouple code merge from exposure
  • DB migration that is compatible across both old and new app versions
  • Stepwise exposure: staging → internal users → selected customers → all users

🧠 Better Release Strategy Design

Key Principle

Release ≠ Code Delivery
Release = Risk Framing + Controlled Exposure

  • Classify the change: is it visible? breaking? reversible?
  • Design rollout method: toggle, staged, canary, delayed exposure
  • Include rollback mechanism before merge (infra and data both)
  • Define observability points: error surge? retry rate? latency spike?
  • Coordinate internally: who needs to know when and why

❓ FAQ

  • Q: Why not fix forward?
    A: That works only when blast radius is controlled and recovery is fast.

  • Q: Is staging enough?
    A: No. Only real traffic reveals integration cracks.

  • Q: Who owns release design?
    A: Every team must own it for what they ship.
