SRE | Recovery Engineering

Reliability is not the words “high availability.” Services have targets, changes have gates, failures have runbooks, and recovery has reconciliation.

04 / Reliability operating blueprint: subject, policy, execution, and evidence control chain
The six stages in the blueprint map one-to-one to the sections below: every node has an action, an owner, and an evidence output.
01

Service objectives

Define acceptable interruption and latency first

Set availability, completion, recovery-time, and recovery-point targets by workflow and tenant tier, with monitors that can verify them.

Execution steps

  1. 01

    Identify critical workflows

  2. 02

    Define SLO, RTO, and RPO

  3. 03

    Break down service, queue, dependency metrics

  4. 04

    Set error budget and escalation

Service objectives: Define acceptable interruption and latency first flow, SOP, and evidence
02

Health checks

Localize issues to service, queue, dependency, and task

Health includes queue backlog, tool failures, model response, writeback result, and tenant-level errors, not just process liveness.

Execution steps

  1. 01

    Check services and dependencies

  2. 02

    Check queues, tasks, retries

  3. 03

    Segment errors by tenant and flow

  4. 04

    Alert and hand off to on-call

03

Change gates

Know what changed and how to roll back every release

Code, policy, model, prompt, tool, and infrastructure changes share one record and are validated in the target topology before expansion.

Execution steps

  1. 01

    Generate change list and impact

  2. 02

    Pass test, review, approval gates

  3. 03

    Roll out and observe error budget

  4. 04

    Rollback or stop propagation

Acceptance evidenceVersion, diff, approvalCanary scope and healthRollback point and operator

04

Migration and backup

Validate state before and after migration

Migration is a repeatable flow of backup, rehearsal, validation, cutover, rollback, and reconciliation, not a one-off script.

Execution steps

  1. 01

    Lock snapshot and backup point

  2. 02

    Rehearse in a shadow environment

  3. 03

    Validate counts, relations, indexes

  4. 04

    Keep rollback window after cutover

Acceptance evidenceBackup version and checksumBefore/after migration diffRollback window and reconciliation
Migration and backup: Validate state before and after migration flow, SOP, and evidence
05

Incident and failover

Run incidents by playbook instead of improvisation

After an alert, follow impact, ownership, communication, degradation, failover, and evidence steps to limit blast radius.

Execution steps

  1. 01

    Confirm impact and severity

  2. 02

    Freeze changes and assign commander

  3. 03

    Enable degrade, throttle, or fallback

  4. 04

    Record decisions and communication

Acceptance evidenceSeverity and impactCommander, participants, timelineFailover result and user impact

06

Recovery review

Service recovery is not business recovery; reconcile outcomes

After recovery, reconcile tasks, writes, audit, and notices to catch duplicate work, missed work, and broken evidence.

Execution steps

  1. 01

    Restore services and dependencies

  2. 02

    Replay or compensate unfinished tasks

  3. 03

    Reconcile outcomes and audit

  4. 04

    Review and update runbook

Acceptance evidenceCompensation and duplicate checkBusiness outcome reconciliationPostmortem actions and due dates

Bring Reliability requirements into a real evaluation

We map the principle to an acceptance checklist for your data, workflow, deployment boundary, and owners.

Region, data, model, operations, and acceptance requirements still need to be confirmed item by item in the project assessment.
