Pro Tip

Always start with the official "Get Started" guides for the language and runtime you intend to use. This will ensure you have the latest best practices and configurations.

Advanced: Durable Functions for State Management

Explore Durable Functions, an extension of Azure Functions that allows you to write stateful workflows in a serverless environment. Build orchestrations and manage complex processes.

  • Understand orchestrator and activity functions.
  • Implement fan-out/fan-in patterns.
  • Handle long-running operations.

Securing Your Azure Functions

Learn essential security practices for your Azure Functions, including authentication, authorization, and managing secrets.

  • Implement API key authentication.
  • Integrate with Azure Active Directory.
  • Use Azure Key Vault for secrets management.

Security Alert

Never hardcode sensitive information like connection strings or API keys directly in your function code. Always use application settings or Azure Key Vault.

Tutorial Details: Your First Azure Function

This section would contain the detailed steps, code examples, and explanations for the first tutorial.


// Example: C# HTTP Trigger Function
using System.Net.Http;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.Extensions.Logging;

public static class HttpTriggerFunction
{
    [FunctionName("HttpTriggerFunction")]
    public static HttpResponseMessage Run(
        [HttpTrigger(AuthorizationLevel.Function, "get", "post")] HttpRequestMessage req,
        ILogger log)
    {
        log.LogInformation("C# HTTP trigger function processed a request.");

        string name = req.GetQueryNameValuePairs()
            .FirstOrDefault(q => string.Compare(q.Key, "name", true) == 0)
            .Value;

        if (name == null)
        {
            name = req.Content?.ReadAsStringAsync().Result;
        }

        return name == null
            ? req.CreateResponse(System.Net.HttpStatusCode.BadRequest, "Please pass a name on the query string or in the request body")
            : req.CreateResponse(System.Net.HttpStatusCode.OK, $"Hello, {name}!");
    }
}
