What you will be able to do

Distinguish delivery revision from infrastructure plan in a realistic devops and sre operations capstone case.
Interpret the delivery evidence and boundary associated with release progression.
Choose an appropriate action involving reliability evidence without exceeding the named operational scope.
Verify recovery closure through an observable service result and reproducible handoff.

Frame DevOps and SRE Operations Capstone

Operate a complete delivery change by connecting reviewed source, immutable artifacts, infrastructure plans, controlled release, telemetry, objectives, and incident-ready recovery evidence.

A team must launch a new report-export worker in staging, prove its reliability, promote the same artifact, and retain a safe response path if production exports fail.

Keep the delivery target, declared intent, execution evidence, reliability boundary, and recovery choice separate. Start with observable state and preserve enough context for another operator to reproduce the decision.

Delivery revision

The delivery revision is the exact reviewed source snapshot that drives build, infrastructure, and release evidence. Within devops and sre operations capstone, this role answers a separate delivery or reliability question and keeps its own evidence.

Approve the worker code and environment definitions as bounded changes. Apply that action to the named service case before widening the rollout, infrastructure scope, or incident response.

Respect this boundary: do not promote an artifact whose source revision differs from review. The observable result is specific: one immutable revision anchors the operating record.

Infrastructure plan

An infrastructure plan compares declared intent with managed state before any target mutation. Within devops and sre operations capstone, this role answers a separate delivery or reliability question and keeps its own evidence.

Review staging addresses, permissions, state scope, and replacement actions. Apply that action to the named service case before widening the rollout, infrastructure scope, or incident response.

Respect this boundary: do not apply a plan that includes unexplained production resources. The observable result is specific: the approved preview contains only the worker's intended staging changes.

Release progression

Release progression promotes the same verified artifact through controlled environments and exposure steps. Within devops and sre operations capstone, this role answers a separate delivery or reliability question and keeps its own evidence.

Verify the digest, deploy to staging, then canary the approved package. Apply that action to the named service case before widening the rollout, infrastructure scope, or incident response.

Respect this boundary: do not rebuild the worker between staging and production. The observable result is specific: the production candidate matches the tested artifact identity.

Reliability evidence

Reliability evidence evaluates a defined user outcome using correctly attributed runtime signals and an objective. Within devops and sre operations capstone, this role answers a separate delivery or reliability question and keeps its own evidence.

Measure eligible export success and latency during staged exposure. Apply that action to the named service case before widening the rollout, infrastructure scope, or incident response.

Respect this boundary: do not approve on host health when user exports are failing. The observable result is specific: the canary meets the export slo without abnormal budget burn.

Recovery closure

Operational closure confirms service behavior and keeps tested mitigation, ownership, evidence, and learning paths available. Within devops and sre operations capstone, this role answers a separate delivery or reliability question and keeps its own evidence.

Record verification, rollback trigger, responder route, and final release state. Apply that action to the named service case before widening the rollout, infrastructure scope, or incident response.

Respect this boundary: do not close the change before production evidence is stable. The observable result is specific: the release is traceable, observable, and recoverable under one operating record.

Apply DevOps and SRE Operations Capstone to One Service Change

Use one bounded delivery decision: A team must launch a new report-export worker in staging, prove its reliability, promote the same artifact, and retain a safe response path if production exports fail.

First, approve the worker code and environment definitions as bounded changes. Then, review staging addresses, permissions, state scope, and replacement actions. Keep both observations attached to the exact revision, environment, or service window.

Next, verify the digest, deploy to staging, then canary the approved package. After that, measure eligible export success and latency during staged exposure. Close the work only after you record verification, rollback trigger, responder route, and final release state.

Recap Before Practice and Prove

Delivery revision: The delivery revision is the exact reviewed source snapshot that drives build, infrastructure, and release evidence. In this service case, approve the worker code and environment definitions as bounded changes. Preserve the boundary: do not promote an artifact whose source revision differs from review.

Infrastructure plan: An infrastructure plan compares declared intent with managed state before any target mutation. In this service case, review staging addresses, permissions, state scope, and replacement actions. Preserve the boundary: do not apply a plan that includes unexplained production resources.

Release progression: Release progression promotes the same verified artifact through controlled environments and exposure steps. In this service case, verify the digest, deploy to staging, then canary the approved package. Preserve the boundary: do not rebuild the worker between staging and production.

Reliability evidence: Reliability evidence evaluates a defined user outcome using correctly attributed runtime signals and an objective. In this service case, measure eligible export success and latency during staged exposure. Preserve the boundary: do not approve on host health when user exports are failing.

Recovery closure: Operational closure confirms service behavior and keeps tested mitigation, ownership, evidence, and learning paths available. In this service case, record verification, rollback trigger, responder route, and final release state. Preserve the boundary: do not close the change before production evidence is stable.
