A company is developing a new on-demand video application that is based on microservices. The application will have 5 million users at launch and will have 30 million users after 6 months. The company has deployed the application on Amazon Elastic Container Service (Amazon ECS) on AWS Fargate. The company developed the application by using ECS services that use the HTTPS protocol.

A. configure the ECS services to use the blue/green deployment type and a Network Load Balancer. Request increases to the service quota for tasks per service to meet the demand.

B. configure the ECS services to use the blue/green deployment type and a Network Load Balancer. Implement Auto Scaling group for each ECS service by using the Cluster Autoscaler.

C. configure the ECS services to use the blue/green deployment type and an Application Load Balancer. Implement an Auto Scaling group for each ECS service by using the Cluster Autoscaler.
