Compute Solutions (1 / 7):

A retail company is running a public-facing e-commerce website in Azure. The site experiences predictable spikes in traffic during sales campaigns, and management wants to minimize costs during normal hours while automatically handling the spikes. The solution must:

Host an HTTP-based web application.
Support custom domains and SSL.
Scale automatically based on a schedule (e.g., during promotions).
Require no container orchestration or Kubernetes knowledge.

Which Azure service is the most suitable?

Answer:

Azure App Service is the best choice here because it:

Provides a fully managed PaaS for hosting web applications with built-in support for custom domains, SSL, and HTTP workloads.
Supports autoscaling based on both metrics (CPU, memory, HTTP queue length) and schedules (e.g., scale out during sales campaigns).
Requires no infrastructure or Kubernetes management.

Other options:

Azure Container Instances: No autoscaling, poor fit for persistent web apps.
Azure Container Apps: Supports scaling but is aimed at microservices/event-driven workloads; App Service is a simpler and cheaper fit for standard web apps.
Azure Kubernetes Service (AKS): Overkill; requires infrastructure management, not aligned with “focus on coding.”
Azure Functions: Best for event-driven workloads, not full-featured websites with sessions, SSL, and predictable schedule-based scaling.
