Objective 1.2

CLF-C02

Identify design principles of the AWS Cloud.

Objective 1.2 sits in Cloud Concepts, which carries 24% of the Cloud Practitioner exam. The questions below are original, written from the official objective title above, and each explanation cites the Amazon Web Services (AWS) page it rests on.

A worked example

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

1-2Cloud Concepts

A team skips full scale load testing because a permanent copy of production would cost too much to keep. Which design principle answers that?

Drive architectures using dataDriving architecture with data means collecting evidence from a running workload. It tells you what to change, not how to afford a test rig.
Improve through game daysGame days rehearse an event in production. Useful, but the blocker here is paying for a second environment, not a lack of practice.
Test systems at production scaleCorrect · your answerCorrect. The cloud lets you create a production-scale test environment on demand and decommission it once the testing is finished.
Consider evolutionary architecturesEvolutionary architecture is about revisiting decisions over the life of a system. Here the obstacle is the price of an environment.

Correct.

Concept

A rented environment can be built for an afternoon and thrown away. That changes which experiments are worth running, not only how they are paid for.

Why C

You stand up a full size copy on demand, run the load through it, then delete it, so the bill is a few hours of compute rather than a second data center.

Source

Test systems at production scale: In the cloud, you can create a production-scale test environment on demand, complete your testing, and then decommission the resources. Because you only pay for the test environment when it's running, you can simulate your live environment for a fraction of the cost of testing on premises…
