Your company is planning to host a web application on a set of EC2 Instances. Based on the initial response, it has now been decided to add a service that would help distribute the traffic across a set of EC2 Instances hosting the application. The main requirements are that the service should be able to scale to a million requests per second. Which of the following would you implement for this requirement?

Answer options:

A.An ECS Cluster
B.A Network Load balancer
C.A Classic Load Balancer
D.An SQS queue

Answer – B
The AWS Documentation mentions the following.
Using a Network Load Balancer instead of a Classic Load Balancer has the following benefits.
· Ability to handle volatile workloads and scale to millions of requests per second.
· Support for static IP addresses for the load balancer. You can also assign one Elastic IP address per subnet enabled for the load balancer.
· Support for registering targets by IP address, including targets outside the VPC for the load balancer.
Option A is incorrect since there is no specific mention in the question on Docker containers.
Option C is incorrect since you need a network load balancer for higher throughput of requests.
Option D is incorrect since there is no mention of the need to distribute messages between components of the application.
