ou pay for AWS resources (e.g. EC2 instances or EBS volumes) you create to store and run your application. You only pay for what you use, as you use it; there are no minimum fees and no upfront commitments.

Question 10

How does ECS leverage Fargate?

Answer 10

With Fargate, the concept of server provisioning, cluster management, and orchestration completely goes away. Amazon ECS uses containers provisioned by Fargate to automatically scale, load balance, and manage scheduling of your containers for availability, providing an easier way to build and operate containerized applications.

Question 11

VS Elastic Beanstalk

Answer 11

AWS Elastic Beanstalk is an application management platform that helps customers easily deploy and scale web applications and services.

Question 12

VS Lambda

Answer 12

AWS Lambda is an event-driven task compute service that runs your code in response to “events” such as changes in data, website clicks, or messages from other AWS services without you having to manage any compute infrastructure.

Question 13

What platform does it run on?

Answer 13

Yes. You can use any AMI that meets the Amazon ECS AMI specification. We recommend starting from the Amazon ECS-enabled Amazon Linux AMI.
