A website that I have designed On Premise has a consistent increase in traffic during certain occasions like Christmas & Thanksgiving. The first year saw a 20% average increase while the second year saw a 40% average increase. It is observed that every year I need to spend on new Servers which lie idle after usage. If I use AWS Cloud resources instead, the advantage that I will get is. (Choose the best answer)

Answer options:

A.I can go Global in minutes
B.I can increase speed & agility of my website
C.I do not need to maintain the DNS name
D.I can save on costs due to the elastic nature of the cloud

Correct Answer: D
As seen from the scenario, every year I need to budget for new servers due to an increase in traffic. This adds to my cost, maintenance of the servers that may not be required at other times in the year. Due to the elastic nature of the cloud, I can directly avail cost benefits by using a pay-as-you-go model and dynamically scaling - OUT & scaling - IN my resources when needed.
Option A is incorrect. Although going global is an advantage of using cloud due to availability of multiple regions, it does not account for our scenario
Option B is incorrect. Speed and agility of a website depends on various factors like application architecture / design, application communication etc..Although a cloud can provide a lot of hosting methodologies like Static web hosting using S3, Using a CDN like CloudFront for performance improvement, it does not account for in our scenario
Option C is incorrect. This is not the best advantage that can be achieved in this scenario. This question does not mention anything about DNS names.
Option D is CORRECT. Using the cloud will have a direct impact on my costs of purchasing new servers each year to support the dynamic increase in load.
