A global telecom firm is planning to launch a new application for its premium customers. This application requires ultra-low latency to EC2 application servers hosted in AWS cloud infrastructure. All application data need to be uploaded to Database servers with optimum latency. IT Head is concerned for the end-to-end connectivity from mobile users to the application servers. As an AWS Consultant, you have been instructed to work on a solution to reduce the number of hops & ensure the latency threshold is committed to end-users.
Which of the following can be deployed to meet the requirement?

Answer options:

A.Create an AWS Wavelength zone within the telecom provider facility & launch Amazon EC2 instance within this zone. Deploy Database servers in the parent region connecting to this AWS Wavelength.
B.Create an AWS Wavelength zone at the nearest edge location & launch Amazon EC2 instance within this zone. Deploy Database servers in the parent region connecting to this AWS Wavelength.
C.Create an AWS Wavelength zone at the nearest edge location & launch Amazon EC2 instance within this zone. Deploy Database servers in the same VPC created in the AWS Wavelength zone.
D.Create an AWS Wavelength zone within the telecom provider facility & launch Amazon EC2 instance within this zone. Deploy Database servers in the same VPC created in the AWS Wavelength zone.

Correct Answer – A
AWS Wavelength can be deployed with Telecom Provider IT infrastructure to provide low latency for mobile users to applications servers deployed on an EC2 instance within AWS cloud. With AWS Wavelength, Compute & Storage services can be launched.AWS Wavelength is connected back to the AWS region for communication with other AWS services. In the above case, application servers can be launched within the EC2 instance in AWS Wavelength deployed at telecom provider facility & database servers can be launched in AWS Region.
Option B is incorrect as creating an AWS Wavelength at the edge location is not a valid option.
Option C is incorrect as creating an AWS Wavelength at the edge location is not a valid option. Also, Database servers need to be deployed in the parent region & not in the AWS Wavelength zone.
Option D is incorrect as Database servers should be created in the parent region & not in AWS Wavelength Zone.
