Cost optimization pillar in AWS - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to select the AWS service that helps reduce costs by automatically adjusting compute capacity.

AWS

service = "[1]"

Drag options to blanks, or click blank then click option'

AAmazon S3

BAmazon EC2 Auto Scaling

CAWS Lambda

DAmazon RDS

💡 Hint

Common Mistakes

Choosing a storage service instead of compute scaling.

Selecting a database service unrelated to compute scaling.

Amazon EC2 Auto Scaling adjusts compute capacity automatically to optimize costs.

2fill in blank

medium

Complete the code to specify the AWS pricing model that offers the lowest cost for steady-state usage.

AWS

pricing_model = "[1]"

Drag options to blanks, or click blank then click option'

ADedicated Hosts

BOn-Demand Instances

CReserved Instances

DSpot Instances

Attempts:

3 left

💡 Hint

Common Mistakes

Confusing On-Demand with Reserved Instances.

Choosing Spot Instances which are cheaper but not guaranteed.

Reserved Instances provide a lower cost for steady, predictable usage by committing to a term.

3fill in blank

hard

Fix the error in the code to correctly identify the AWS tool used for cost monitoring and budgeting.

AWS

tool = "[1]"

Drag options to blanks, or click blank then click option'

AAWS Config

BAWS CloudTrail

CAmazon CloudWatch

DAWS Cost Explorer

Attempts:

3 left

💡 Hint

Common Mistakes

Choosing CloudTrail which tracks API calls, not costs.

Selecting CloudWatch which monitors performance metrics.

AWS Cost Explorer helps visualize and monitor AWS costs and usage.

4fill in blank

hard

Fill both blanks to create a cost-effective storage class and lifecycle policy in AWS S3.

AWS

storage_class = "[1]"
lifecycle_action = "[2]"

Drag options to blanks, or click blank then click option'

AS3 Intelligent-Tiering

BS3 Standard

CTransition to Glacier

DDelete immediately

Attempts:

3 left

💡 Hint

Common Mistakes

Using S3 Standard which is more expensive for infrequent access.

Deleting data immediately which may cause data loss.

S3 Intelligent-Tiering automatically moves data to the most cost-effective access tier. Lifecycle policies can transition objects to Glacier for cheaper long-term storage.

5fill in blank

hard

Fill all three blanks to define a cost-optimized compute resource with spot pricing, auto scaling, and a budget alert.

AWS

compute_type = "[1]"
auto_scaling = "[2]"
budget_alert = "[3]"

Drag options to blanks, or click blank then click option'

ASpot Instances

BAmazon EC2 Auto Scaling

CAWS Budgets

DOn-Demand Instances

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing On-Demand with Spot Instances for cost savings.

Not using budget alerts to monitor spending.

Spot Instances reduce compute costs by using spare capacity. Auto Scaling adjusts capacity automatically. AWS Budgets helps monitor and alert on spending.
