Answer is C. https://aws.amazon.com/eventbridge/ Amazon EventBridge is a serverless event bus that makes it easier to build event-driven applications at scale using events generated from your applications, integrated Software-as-a-Service (SaaS) applications, and AWS services. https://docs.aws.amazon.com/AmazonECS/latest/developerguide/AWS_Fargate.html AWS Fargate is a technology that you can use with Amazon ECS to run containers without having to manage servers or clusters of Amazon EC2 instances.

Answer is C. Explanation: cost effective means serverless is best way to go. A-RIs would be running continuously once purchased and eventhough we get upfront discount,its still being charged for 1/3 yr reservation B-Lambda can only run 15 mins max C-Fargate is best choice,it is serverless D-ECS is based on EC2s which need to be provisioned

I thought of Lambda but when I looked at 2 hours then it makes sense to go for ECS fargate option.

C. Use an Amazon Elastic Container Service (Amazon ECS) Fargate task triggered by an Amazon EventBridge (Amazon CloudWatch Events) scheduled event. Fargate is cheaper than EC2
