3.3 Identify AWS compute services.
Objective 3.3 sits in Cloud Technology and Services, which carries 34% of the Cloud Practitioner exam. The questions below are original, written from the official objective title above, and each explanation cites the AWS page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A team runs containers on Amazon ECS and wants no servers to manage and no capacity planning at all. Which capacity option fits?
The 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 this answer
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.
- AChoosing EC2 capacity means you pick the instance type and the number of them, and you own the scaling and patching of every host.
- Correct. Fargate is a serverless, pay-as-you-go compute engine, so there are no servers to manage and no capacity planning to do.
- CECS Anywhere registers an external machine, such as an on-premises server, into your cluster. That is more infrastructure to run, not less.
- DAn Auto Scaling group keeps a chosen number of EC2 instances alive. It automates the count while leaving everything on those instances to you.

Sample question 1 of 3
A nightly transform takes about 40 minutes to complete. Why is an AWS Lambda function a poor fit for it?
Sample question 2 of 3
A team must choose an EC2 instance type for a new application. What does the instance type determine?
Sample question 3 of 3
A Lambda function is processor bound and runs slowly. A colleague suggests raising its memory setting. Does that help?
