Your company is planning to move to the AWS Cloud.
You need to give a presentation on the cost perspective when moving existing resources to the AWS Cloud.
Considering Amazon EC2, which of the following is an advantage from the cost perspective?
Click on the arrows to vote for the correct answer
A. B. C. D.Answer - C.
One of the advantages of EC2 Instances is the per-second billing concept.
This is also given in the AWS documentation.
With per-second billing, you pay for only what you use.
It takes the cost of unused minutes and seconds in an hour off of the bill.
So, you can focus on improving your applications instead of maximizing usage to the hour especially if you manage instances running for irregular periods of time, such as dev/testing, data processing, analytics, batch processing and gaming applications.

https://aws.amazon.com/ec2/pricing/When moving existing resources to the AWS Cloud, it is important to consider the cost perspective. Amazon EC2 (Elastic Compute Cloud) is a web service that provides resizable compute capacity in the cloud, designed to make web-scale cloud computing easier for developers.
Out of the given options, option C is the correct answer: "The ability to only pay for what you use" is an advantage from the cost perspective. This is because with Amazon EC2, you can launch as many or as few virtual servers as you need, configure security and networking, and manage storage. You only pay for what you use, which means you don't have to make any upfront investments and don't need to worry about capacity planning.
Option A, "Having the ability of automated backups of the EC2 instance, so that you don't need to worry about the maintenance costs" is incorrect because while automated backups can help with the maintenance of the EC2 instance, it does not directly affect the cost perspective.
Option B, "The ability to choose low cost AMI's to prepare the EC2 Instances" is incorrect because while choosing a low cost AMI (Amazon Machine Image) can help reduce costs, it is not an inherent advantage of Amazon EC2 itself.
Option D, "Ability to tag instances to reduce the overall cost" is incorrect because while tagging instances can help you track and manage your resources, it does not directly reduce the overall cost.
In conclusion, the advantage from a cost perspective when moving existing resources to the AWS Cloud with Amazon EC2 is the ability to only pay for what you use.
