Question

Difficulty: MediumConfigure Azure App Service Plans

A non-profit organization is deploying a public-facing event registration web application to Azure App Service. The hosting plan for the web application must meet the following requirements:
- Allow the application to be accessed using a custom domain with an SSL binding.
- Support scaling up to a maximum of 10 instances to handle traffic spikes during event registrations.
- Support at least one staging slot to perform testing before deploying to production.
You need to identify the most cost-effective App Service plan tier that meets all requirements.
Which App Service plan tier should you select?

  1. A
    Free (F1)
  2. B
    Basic (B1)
  3. Standard (S1)Answer
  4. D
    Premium v3 (P1v3)

Answer

Standard (S1)
The Standard (S1) tier is the most cost-effective tier that satisfies all requirements. It supports custom domains, SSL bindings, scaling up to 10 instances, and up to 5 staging slots.

Step-by-Step Solution

1
Evaluate the requirement for staging slots.
Staging slots require at least the Standard tier.
Free and Basic tiers do not support deployment slots.
2
Evaluate the scaling requirement of up to 10 instances.
The Standard tier supports scaling up to 10 instances.
The Basic tier is limited to a maximum of 3 instances, whereas the Standard tier supports up to 10 instances.
3
Identify the most cost-effective tier that meets all requirements.
The Standard tier is selected.
Both Standard and Premium v3 meet all requirements, but Standard is more cost-effective than Premium.

Key Concept

Determining the minimal App Service Plan pricing tier based on features such as staging slots, instance scaling limits, and custom domain SSL bindings.
