Module 17 / Lesson 01

Choose an appropriate runtime

A notebook is useful for exploration but is not automatically an operational service. Choose a runtime that fits request duration, dependencies, scaling, networking, identity, and the client’s platform. Managed application and serving options can reduce some operational work but introduce their own constraints.

Document what the runtime owns and what your team owns. Avoid adding containers or orchestration systems solely for appearance; choose them when the workload or existing environment warrants them.

Apply the ideaCompare two deployment options against the support copilot’s actual requirements.
Module 17 / Lesson 02

Package for reproducibility

Pin dependencies and record the interpreter/runtime. Separate build-time files from runtime configuration and secrets. Include health checks that reflect the service’s readiness without making every check expensive or exposing internals.

A clean-environment setup test often reveals hidden assumptions. Keep data initialization and migrations deliberate. Do not require an undocumented manual notebook step for every release.

Apply the ideaWrite a reproducible setup and smoke-test sequence for another engineer.
Module 17 / Lesson 03

Define network and identity boundaries

Record inbound users, outbound dependencies, identity flows, and data locations. Verify that the deployed service can access only what it needs and that users cannot bypass its access policy through another exposed endpoint.

Network restrictions complement application authorization; neither replaces the other. A private endpoint can still receive an unauthorized request from an internal user. Review operational access for maintainers too.

Apply the ideaAnnotate an architecture diagram with service identities and permitted connections.
Module 17 / Lesson 04

Separate configuration from code

Environment-specific URLs, resource identifiers, quotas, and feature switches should be explicit configuration. Validate required settings on startup. Keep secrets in the approved platform mechanism, never in published lab files.

Infrastructure/configuration as code makes review and recreation easier, but can also apply destructive changes. Inspect target resources and migration effects before deployment, especially when importing existing systems.

Apply the ideaCreate an example configuration containing names and placeholders only, with no credentials.
Module 17 / Lesson 05

Verify release and cleanup

Smoke tests should exercise a critical read, an expected denial, and a safe representative workflow after deployment. Rehearse rollback against compatible data and configuration. Identify any actions rollback cannot reverse.

A lab should include teardown and verify that billable resources are removed or stopped as intended. Record what was actually deployed. A local demo is useful, but must not be described as a completed managed-platform release.

Apply the ideaCreate a release checklist with smoke tests, rollback trigger, and resource cleanup.

Worked scenario

A deployment succeeds, but the application uses a development catalog because a configuration value was copied incorrectly. A post-release smoke test should inspect a harmless known fixture and confirm the environment identity and expected access boundary. A process exit code alone cannot establish correct deployment.

Practical assignment

This is a practical design or implementation assignment. Use synthetic data. Where managed services are required, verify account access, costs, supported features, and cleanup before provisioning.
  1. Choose a runtime and document reasons.
  2. Package the local reference application.
  3. Define deployment-specific identity and resource configuration.
  4. Run a clean setup and smoke test.
  5. Rehearse rollback or write the exact managed rehearsal plan.
  6. Record resource cleanup and unverified environment-specific steps.

What to submit

Submit the artifacts named above, a short explanation of your decisions, and evidence of the checks you performed. Distinguish measured results from estimates and designs from executed integrations.

Review dimensionSubmission evidence
CorrectnessShow the expected behavior and a meaningful counterexample.
ReproducibilityState setup, inputs, versions, and what was actually executed.
Delivery judgmentExplain the client impact, alternative, and unresolved assumption.
Operational boundaryIdentify permissions, failure behavior, and any resource cleanup.

Knowledge check

1. Is a successful deployment command sufficient?
2. Where should runtime secrets live?
3. Does private networking replace authorization?

Answer guide
  1. No, verify the actual user path and environment. A deployment can succeed with incorrect configuration or permissions.
  2. In an approved secret mechanism. Secrets require appropriate storage, access, and rotation.
  3. No. Internal callers still need an appropriate access decision.

References & next step

Platform examples are environment-dependent. Start with the official documentation in the reference library and verify the exact cloud, region, privileges, and versions you use.
