Some of the main use cases in which AWS Lambda can be used are as follows:
- Web Application: We can integrate AWS Lambda with other AWS Services to create a web application that can scale up or down with zero administrative effort for server management, backup or scalability.
- Internet of Things (IoT): In the Internet of Things applications, we can use AWS Lambda to execute a piece of code on the basis of an event that is triggered by a device.
- Mobile Backend: We can create Backend applications for Mobile apps by using AWS Lambda.
- Real-time Stream Processing: We can use AWS Lambda with Amazon Kinesis for processing real-time streaming data.
- ETL: We can use AWS Lambda for Extract, Transform, and Load (ETL) operations in data warehousing applications. AWS Lambda can execute the code that can validate data, filter information, sort data or transform data from one form to another form.
- Real-time File processing: AWS Lambda can also be used for handling any updates to a file in Amazon S3. When we upload a file to S3, AWS Lambda can create thumbnails, index files, new formats etc in real-time.
