Hands-On Azure for Developers

Scaling

One of the most important features of serverless components and architectures is their ability to scale out as they are loaded more and more. While in traditional PaaS services, you often have to worry about available instances or scaling configuration. Serverless allows for the seamless handling of incoming requests, even if a service is hit by an unexpectedly high traffic. In this section, we will talk about the scaling capabilities of Azure Functions, with a focus on differences between consumption and App Service models.
