Topic 1 Question 223
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 solutions architect needs to implement updates to the application by using blue/green deployments. The solution must distribute traffic to each ECS service through a load balancer. The application must automatically adjust the number of tasks in response to an Amazon CloudWatch alarm.

Which solution will meet these requirements?
- 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.
- 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.
- 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.
- Configure the ECS services to use the blue/green deployment type and an Application Load Balancer. Implement Service Auto Scaling for each ECS service.

- 正解だと思う選択肢: D
  A and B are out, it says the app uses HTTPS. C is out because we have Fargate and there is no Cluster Auto Scaling there. So, it's D because we have Service Auto Scaling. -> https://repost.aws/knowledge-center/ecs-fargate-service-auto-scaling

- 正解だと思う選択肢: C
  AB are eliminated because of NLB C has Auto Scaling Group with Cluster Autoscaler: As per ChatGPT - By implementing an Auto Scaling group for each ECS service using the Cluster Autoscaler, you can automatically adjust the number of tasks (containers) based on the demand. The Cluster Autoscaler scales the ECS tasks in response to CloudWatch alarms, allowing you to scale the infrastructure up or down to handle the increasing number of users.

  Answer is D. For those voting C, remember that it's on Fargate, so there is no such cluster autoscaling.
