Introduction to Azure Functions

Azure Functions is a serverless computing platform that allows you to run code without managing servers. It provides a wide range of triggers and bindings that allow you to connect to various services and resources. Azure Functions can be deployed to Azure, on-premises, or in the cloud. You can use Azure Functions to build web apps, mobile apps, and IoT apps. Azure Functions is built on top of the Azure Functions runtime, which is a lightweight runtime that runs your code in a container. The runtime provides a set of APIs that you can use to interact with your code. Azure Functions also provides a set of tools and services that you can use to manage your functions, including the Azure Functions Portal, Azure Functions CLI, and Azure Functions Extensions.

Durable Functions for Statefulness

Durable functions are functions that can be executed multiple times and maintain their state between executions. Durable functions are useful for building applications that require stateful behavior, such as chatbots, inventory management systems, and financial applications. Azure Functions provides a set of features that allow you to create durable functions, including the Durable Functions runtime, the Durable Functions SDK, and the Durable Functions Extension. The Durable Functions runtime provides a set of APIs that you can use to create durable functions. The Durable Functions SDK provides a set of tools and libraries that you can use to develop durable functions. The Durable Functions Extension provides a set of features that you can use to enhance the functionality of durable functions.

Creating a Serverless API Using Azure Functions

Azure Functions provides a set of features that allow you to create a serverless API. A serverless API is a web service that is hosted on the cloud and can be accessed by clients over the internet. Azure Functions provides a set of triggers and bindings that you can use to create a serverless API. You can use the HTTP trigger to create a web service that responds to HTTP requests. You can use the Timer trigger to create a web service that runs at a specific time. You can use the Queue trigger to create a web service that processes messages from a queue. You can use the Blob trigger to create a web service that processes files from a blob storage account. You can use the Service Bus trigger to create a web service that processes messages from a service bus.
