Overview of Azure Functions

by Leave a Comment

Azure functions are used to isolated small pieces of logic.These functions are triggered when some triggering even happens.

  • Azure fucntions is a Serverless computing technology
  • Azure functions can be created using C#,Typescript and many different technologies
  • Azure functions are based on triggers,events and isolated code.
  • Events cause trigger to fire which causes the function to execute.

Some of the events or triggers which cause Function to execute are:

  • HTTP Request
  • Schedule
  • Blob storage
  • Queue storage
  • Event Grid
  • Event Hub
  • Service Bus Queue
  • Service Bus Topic

Azure functions is a type of App service.Other examples of App Services are Web App and Logic Apps.The benefit of Azure function is that since it is based on serverless architecture so you don’t need to be concerned with the lower level details of the functions such as mananging the OS and middleware.

This makes it easy not only to develop but also to deploy and scale the application.

Following is a basic function which is executed when http trigger is fired

import { AzureFunction, Context, HttpRequest } from “@azure/functions”
const httpTrigger: AzureFunction = async function (context: Context, req: HttpRequest): Promise<void> {
context.log(‘HTTP trigger function processed a request.’);
constname= (req.query.name|| (req.body&&req.body.name));
if (name) {
context.res= {
// status: 200, /* Defaults to 200 */
body: “Hello “+ (req.query.name||req.body.name)
};
}
else {
context.res= {
status: 400,
body: “Please pass a name on the query string or in the request body”
};
}
};
export default httpTrigger;

Understanding Azure function

by Leave a Comment

azure function is a way to implement serverless computing in azure.This means that the developer is not concerned about things such as managing infrastrcuture,scalling and deployment.Instead developer can focus on business logic.

Function is executed when an action occurs.Here action is the event which triggers the function.That is why you need to defined the trigger when defining ypur function.
There are different types of trigggers such as:

  • HTTP Here function execute when there is HTTP Request
  • Timer Function executes in a scehdule
  • Queue storage Function executes based on the mesaages in a queue
  • Event Hub Function executes when there is an event in event hub

You can create Azure function in Azure portal or Visual Studio or Visual Studio Code.Here we will look how to define function using Visual Studio Code

You declare Azure function in a static class as a static method:

public static class SimpleAzureFucntion
{
[FunctionName("SimpleAzureFucntion")]

public static async Task&lt;IActionResult&gt; Run()
{
}

}

As you can observe we have specified the Fucntion attribute here.This attribute is required when declaring functionThe function is named Run.

We now need to specify the trigger when this fucntion will be called.We specify this as an attribute on the fucntion argument.
Here we are soecifying the HttpTrigger on the first argument of type HttpRequest which will be contain the http request.


public static async Task<IActionResult> Run(

[HttpTrigger(AuthorizationLevel.Anonymous, “get”, “post”, Route = null)] HttpRequest req,

We can also add other arguments to this fucntion like a normal function.

public static async Task<IActionResult> Run(

[HttpTrigger(AuthorizationLevel.Anonymous, “get”, “post”, Route = null)] HttpRequest req, ILogger log)

Azure Web Apps
Azure App Service is used for creating HTTP-based service and could be used for hosting web applications, REST APIs, and mobile back ends.It comes in the is a platform-as-a-service or PaaS deployment model.
It supports the following languages:

  • ASP.NET
  • ASP.NET Core
  • Java
  • Ruby
  • Node.js
  • PHP
  • Python

There are numerous options for hosting web applications in Azure but Web Apps is best option in most cases.You can create web application in azure using the Web Apps in App Service by using either of the following:

  • Portal
  • Powershell
  • CLI

Portal

If you want to create Web App using the portal then you can use the following steps:
1.Select the Web category in the portal

azure portal web app

2.Select the Web App

3.Provide required details such as:

  • WebApp name this should be gloablly unique as it uses the domain .azurewebsites.net
  • Publish method docker or code
  • Stack such as .NET or Java
  • OS Windows or Linux
  • Region Where you want to host your app service
  • App Service Plan Dev/Production or Isolated

CLI

1.Before creating the App service you need to create app service plan.You can create it using the az appservice plan create command

az appservice plan create --name NameOfAppServicePlan --resource-group NameOfResourceGroup --sku FREE

2.Create web app in the newly created App Service plan.

az webapp create --resource-group NameOfResourceGroup --plan NameOfAppServicePlan --name NameOfApp

3.If you want to connect to database then you need to configure it in the Startup classes ConfigureServices method:

services.AddDbContext<DatabaseContext>(options =>options.UseSql("Data Source=localdatabase.db"));
