Azure Function
Azure Functions is a serverless computing service and is hosted on the Microsoft Azure public cloud. It is designed to accelerate and simplify application development. The cloud provider takes care of all the headaches of running the server, dynamically managing the resources of the machine, etc. It also provides auto scalability.
Serverless applications, also known as Function-as-a-Service or FaaS, is an offering from most of the enterprise cloud providers in which they allow the users to only write code and the infrastructure behind the scenes is managed by them.
Azure Functions is the event-based serverless application framework which can automatically scale up and down based on the executions that are being triggered. This Microsoft Azure service allows you to run small pieces of code in Node.js, C#, Python, PHP and Java without any infrastructure configurations.
Here, we will see about Azure Function.
Purpose
Azure Functions lets you execute your code in a serverless environment without having to first create a VM or publish a web application.
Key Features
- Intuitive, browser-based user interface - You can write code in the easy-to-use web interface.
- write code in different programming languages
- pay per function execution
- parallel execution when multiple triggers occur
- Supports Continuous Deployment and Integration

Step 5
In this blade, you can able to see many triggers. Search for Blob Storage trigger function here.
- In that, we need to give function name
- Next enter path of Container/Blob
- Choose our storage account

In that, choose account connection as your storage account details and click on create
![Blob Trigger in Azure Portal]()
Now, just view code+Test for Blob trigger function.

And also Test/Run the code
![Blob Trigger in Azure Portal]()
Open the log and check its connected

Step 6
Now, we need to create containers and blob in storage account for getting the log details in functions. So, move to storage account.
![Blob Trigger in Azure Portal]()
Then, click on container and enter the name & access level.
![Blob Trigger in Azure Portal]()
Its looks like this window.
![Blob Trigger in Azure Portal]()
Next, click on upload to upload the file in container
![Blob Trigger in Azure Portal]()
upload the file
![Blob Trigger in Azure Portal]()
Now, its added to container
![Blob Trigger in Azure Portal]()
Output
Now, move to functions and open the logs. we can successfully run our blob trigger function here. The output will look like this.
