AWS Solutions Architect EC2 (100% accurate)

What is EC2? correct answers Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing you to quickly scale capacity, both up and down, as your computing requirements change. What is the general conscious around AWS Pricing correct answers While the number and types of services offered by AWS have increased dramatically, our philosophy on pricing has not changed. You pay as you go, pay for what you use, pay less as you use more, and pay even less when you reserve capacity. Projecting costs for a use case, such as application hosting, can be challenging, because a solution typically uses multiple features across multiple AWS products, which in turn means there are more factors and purchase options to consider.
