App Service plans and scaling

Shared compute tier/capacity with vertical and horizontal scaling.

Key points

  • Plan defines region, operating system, tier, worker size, and instance capacity.
  • Apps in one plan share its compute workers.
  • Scale up changes tier or worker size; scale out changes instance count.

Best-known use cases

  • Add workers for increased request volume.
  • Move to a tier that supports a required App Service feature.

What candidates often confuse it with

  • Plan vs app: shared compute boundary vs workload configuration.
  • Scale up vs scale out: more capable worker vs more workers.

Key takeaway

Change the App Service plan when the requirement concerns compute capacity, instance count, or tier-gated features.

Mode

Exam fidelity: Microsoft does not publish a fixed live question count or guarantee a question-type mix for AZ-104. This lane counts multiple-choice and multiple-response items as exam-style practice. Ordering, matching, and case-study items are supplemental site exercises and do not count toward exam-style accuracy. Practice percentages do not reproduce Microsoft's scaled scoring, and difficulty labels describe this site's Intermediate-level scenario complexity rather than a Microsoft-published question rating.
