AWS Certified Cloud Practitioner (CLF-C01)- AWS Lambda

The video provides an overview of AWS Lambda, a service that enables serverless computing by executing code in response to events without managing servers. It highlights the cost efficiency of Lambda compared to EC2, as users only pay for compute time used. The video explains Lambda's event-driven nature, supporting languages, and user responsibilities. It also covers Lambda's limits, such as memory allocation and execution time, and presents use cases like processing S3 uploads and IoT data. The video concludes with a preview of AWS Elastic Beanstalk.

What is a key advantage of AWS Lambda over EC2 instances?

• Lambda supports unlimited execution time.

• Lambda charges only for the compute time used.

• Lambda requires manual scaling.

• Lambda allows direct server access for configuration.

How does AWS Lambda execute code?

• By running continuously on a server.

• By responding to specific events.

• By using a dedicated server for each function.

• By requiring manual start and stop.

Which of the following is a responsibility of the user when using AWS Lambda?

• Handling load balancing manually.

• Ensuring the code is bug-free.

• Managing the underlying infrastructure.
