Question 3
Which AWS service allows you to run and manage Docker containers without managing the underlying servers using a serverless compute engine?
Answer: AWS Fargate is a serverless compute engine for containers that works with Amazon ECS and EKS, removing the need to provision or manage EC2 instances.
Question 4
What AWS service automatically deploys, scales, and manages web applications without requiring you to manage the underlying infrastructure?
Answer: AWS Elastic Beanstalk automatically handles deployment, capacity provisioning, load balancing, and scaling for web applications, while you retain full control of the underlying resources.
