How does serverless computing work?

Cloud providers offer serverless computing functions through Function as a Service (FaaS). Developers code these functions on serveless platform in below steps:

1. Coding the Functionality: The developer codes specific application functionality.
2. Event Definition: The developer then specifies the event/HTTP request to trigger that function.
3. Execution: The cloud service provider execute the function on command.
4. The user sees the result of the executed function inside the application.
