Explanation:

1. 5 common cloud characteristics which are defined by NIST are :

on-demand self-service, broad network access,resource pooling,rapid elasticity and measured service

2.

Elasticity in Cloud computing means that the computing resources can be scaled outward and inward automatically as per the demand.

3.

SaaS stands for Software as a Service,It is a software distribution model where the cloud providers host applications and makes them accessible over the Internet ,which can be accessed anywhere using browser.

4.

EC2 stands for Elastic Compute Cloud,it is a service in AWS using which we can create and run virtual machines on the cloud.
