Azure Functions

This covers the essentials for building serverless functions on Azure, from HTTP APIs and message processing to scheduled jobs and blob triggers. You get CLI commands for spinning up function apps, references for Node.js implementations and Terraform configs, plus guidance on bindings that let you connect to Azure services without writing SDK boilerplate. The best practices section is practical about managed identity, Key Vault, and Application Insights. If you're already in the Azure ecosystem and need event-driven compute without managing servers, this gets you from zero to deployed. The Durable Functions callout for long-running work is spot on.

Overview

Azure Functions enables serverless computing on Microsoft Azure. Build event-driven applications with automatic scaling, flexible bindings to various Azure services, and integrated monitoring through Application Insights.

When to Use

HTTP APIs and webhooks
Message-driven processing (Service Bus, Event Hub)
Scheduled jobs and CRON expressions
File and blob processing
Queue-based workflows
Real-time data processing
Microservices and backend logic
Integration with Azure ecosystem services

Quick Start

Minimal working example:

# Install Azure Functions Core Tools
curl https://aka.ms/install-artifacts-ubuntu.sh | bash

# Login to Azure
az login

# Create resource group
az group create --name myapp-rg --location eastus

# Create storage account (required for Functions)
az storage account create \
  --name myappstore \
  --location eastus \
  --resource-group myapp-rg \
  --sku Standard_LRS
