AWS Lambda can handle a few requests per day or a thousand requests per day. One can even scale an application automatically or by adjusting the individual units of consumption. This eliminates the need to add or remove servers which can be resource-intensive.

Amazon charges you only for each millisecond that your code executes, and on the number of times, your application triggers the code. Hence. you pay only for the compute time that your application uses and save up to 17% on overall development cost.

Serverless applications have built-in availability and fault tolerance, avoiding the need to create such capabilities. If one server fails, the system will keep running on a different machine. You can even access the abundance of such resources available easily to all.

You can integrate with other AWS services easily to create functionally complete applications. You have the privilege to configure triggers to invoke a function in response to events, HTTP requests, and other in-app activities. Lambda allows you to build, run, and operate your applications without provisioning or managing servers.

The ability to pipeline requests into a single Lambda function for monitoring is hugely beneficial. You can monitor application activity such as APIs calls, errors, and code performance in real-time. You can even use the event-based architecture to deploy, execute, and measure changes within milliseconds.
