Learn Azure Serverless Functions in a Weekend - Azure Functions to Process Blob Storage

This lecture covers the development of an Azure function that triggers when a BLOB is added to a container. The function processes the BLOB content and saves the output to another container. The lecture explains creating a BLOB storage trigger, processing the BLOB content by decoding it to UTF-8, and adding a binding to write the processed content to a target container. The session concludes with testing the function chain to ensure proper BLOB processing and storage.

What triggers the Azure function discussed in the lecture?

• An HTTP request

• A new BLOB added to the container

• A timer event

• A database update

What is the main purpose of the second Azure function?

• To send an email notification

• To create a new BLOB container

• To process and decode BLOB content

• To delete old BLOBs

Which format is used to decode the BLOB content?

• Base64

• UTF-8

• UTF-16

• ASCII

What line is added to the BLOB content during processing?

• Analyzed by the script

• Verified by the user

• Checked by the system

• Processed by the function two

What is the direction of the binding used in the function?

• None

• Both

• In

• Out

What happens to the BLOB after it is processed by the second function?

• It is deleted

• It is archived

• It is moved to a different storage account

• It is written to a target container

What is the expected outcome after the function app is started?

• The function fails to start

• The function processes existing BLOBs

• The function creates a new BLOB

• The function sends a notification
