Answer the following general questions with respect to serverless computing:

$1.$ What is serverless computing? Give three examples of applications that fit into this novel model. For each example

application, give concrete arguments that support the suitability of serverless computing to the application. Also, discuss what

serverless computing cannot do$?$

$2.$ What are the main differences between PaaS $($Platform as a Service$)$ and FaaS $($Function as a Service$)$ delivery models?

$3.$ One key aspect of Cloud Computing is economics. That is$,$ the question of whether Cloud Computing is a costeffective endeavor. FaaS is $$ideal$$ for short and asynchronous computations, such as the creation of a thumbnail for each

image file that is uploaded to an object store $($e$.$g$.,$ Amazon S$3),$ but not for all applications.
