Scaling Azure Functions

When using PaaS services, you can configure how your application will behave when CPU utilization hits the maximum allowed value, or the number of requests exceeds the threshold. However, Azure offers services in other models—one of the most interesting is serverless architecture, which abstracts control even more in favor of easier configuration, minimum maintenance, and the ability to focus on delivering a business value.

In this section, you will see the differences between Azure App Service and Azure Functions when it comes to scaling, both from a technical and conceptual point of view.

Scaling serverless applications

When you are using serverless services (such as Azure Functions, Azure Cosmos DB, or Azure Event Grid), you have limited options when it comes to configuring the feature. Here are some examples:
