Zorluk: ZorConfigure Azure App Service Plans

An administrator is planning the deployment of a critical web application to Azure App Service. The application has the following hosting requirements:
- Must automatically scale out up to 1212 instances during periods of high CPU utilization.
- Must support at least 22 deployment slots to enable zero-downtime deployments.
- Must minimize overall hosting costs.

Which App Service plan pricing tier should you select to meet these requirements?

  1. A
    Standard (S1)
  2. Premium v3 (P1v3)Cevap
  3. C
    Basic (B1)
  4. D
    Isolated v2 (I1v2)

Cevap

Premium v3 (P1v3)
The Premium v3 (P1v3) pricing tier is correct because it supports automatic scale-out up to 3030 instances (meeting the 1212 instances requirement) and supports up to 2020 staging slots (meeting the 22 slots requirement), while being the most cost-effective option that satisfies all criteria.

Adım Adım Çözüm

1
Evaluate the scaling requirements against the instance limits of the App Service plan tiers.
Basic (B1) supports up to 33 instances (manual only). Standard (S1) supports up to 1010 instances (automatic). Premium v3 (P1v3) supports up to 3030 instances (automatic). Isolated v2 (I1v2) supports up to 100100 instances (automatic). Standard (S1) and Basic (B1) are eliminated because they cannot scale to 1212 instances.
This step determines which tiers can satisfy the scaling target of 1212 instances.
2
Evaluate the deployment slot requirements for the remaining tiers.
Both Premium v3 (P1v3) and Isolated v2 (I1v2) support up to 2020 deployment slots, which easily satisfies the requirement of at least 22 slots.
This step ensures that the hosting environment can support zero-downtime deployment workflows using staging slots.
3
Compare the cost profiles of the remaining compliant tiers to find the most cost-effective option.
Premium v3 (P1v3) operates on multi-tenant dedicated hardware and is significantly cheaper than Isolated v2 (I1v2), which runs inside a dedicated App Service Environment (ASE). Premium v3 is chosen as the most cost-effective tier.
This satisfies the cost-minimization constraint of the scenario.
