Infra Notes

Infrastructure handover checklist: make operations repeatable

Use an infrastructure handover checklist covering ownership, architecture, deployment, observability, access, backup, rollback, and known risks.

Problem

Infrastructure work becomes risky when only one person understands how it works.

Why it happens

Teams often optimize for quick delivery but skip documentation, naming standards, handover notes, and operational clarity.

Recommended approach

Optimize for predictable operation: repeatable automation, clear repository structure, consistent naming, documented decisions, explicit ownership, and tested recovery steps.

Signals of healthy infrastructure

Good signs:

  • A README that explains purpose, ownership, deployment, and recovery
  • Standardized variables
  • Repeatable Terraform or Ansible flow
  • Tested rollback and recovery steps
  • Documented ownership
  • Minimal hidden manual steps

Use this when

  • Production infrastructure
  • Team-managed systems
  • Client work
  • Consulting work
  • Long-lived internal platforms

Avoid this when

  • Disposable experiments
  • Throwaway prototypes

Minimum infrastructure handover checklist

Purpose and ownership

  • What business or platform capability does the system provide?
  • Who owns product decisions, technical changes, and incidents?
  • Where are the repository, issue tracker, service catalog, and escalation contacts?

Architecture and dependencies

  • Diagram the request path, trust boundaries, data stores, queues, and external integrations
  • Record cloud accounts, regions, clusters, namespaces, domains, and certificates
  • Identify single points of failure and capacity constraints

Deployment and rollback

  • Document the exact deployment command or pipeline
  • Explain environment promotion and required approvals
  • Provide a tested rollback path and last-known-good reference
  • Separate generated secrets from example configuration

Operations

  • Link dashboards, logs, alerts, SLOs, and runbooks
  • Document backup scope, retention, restore procedure, RTO, and RPO
  • List recurring maintenance, certificate renewal, upgrades, and cost checks
  • Record known failure modes and current technical debt

Access and security

  • Identify identity providers, privileged roles, break-glass access, and review cadence
  • Explain how secrets are created, rotated, and revoked without exposing their values
  • Document network restrictions and audit-log locations

Prove the handover

Ask the receiving engineer to perform a supervised task using only the documentation:

  1. Locate the current production revision
  2. Make or simulate a safe deployment
  3. Find the relevant dashboard and logs
  4. Explain the rollback decision
  5. Locate backup and restore evidence

Every undocumented question becomes a concrete improvement. A handover meeting alone is not durable documentation.

Definition of done

The system is ready to hand over when another authorized engineer can deploy, diagnose, recover, and escalate it without private messages or undocumented knowledge from the original author.
