A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

3-3Cloud Technology and Services

A team runs containers on Amazon ECS and wants no servers to manage and no capacity planning at all. Which capacity option fits?

Amazon EC2 instancesChoosing EC2 capacity means you pick the instance type and the number of them, and you own the scaling and patching of every host.
Amazon ECS AnywhereECS Anywhere registers an external machine, such as an on-premises server, into your cluster. That is more infrastructure to run, not less.
AWS FargateCorrect · your answerCorrect. Fargate is a serverless, pay-as-you-go compute engine, so there are no servers to manage and no capacity planning to do.
EC2 Auto Scaling groupsAn Auto Scaling group keeps a chosen number of EC2 instances alive. It automates the count while leaving everything on those instances to you.

Correct.

Concept

Container orchestration and the machines underneath it are two separate decisions. You choose a scheduler for how tasks run, then choose who owns the hosts those tasks land on.

Why C

When nobody on your side is meant to own a host, the right capacity option is the one with no instances to size, patch or scale. You declare processor and memory per task and pay for what runs.

A Lambda function is processor bound and runs slowly. A colleague suggests raising its memory setting. Does that help?
