ECS service auto scaling in AWS - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the minimum number of tasks for ECS service auto scaling.

AWS

MinCapacity: [1]

💡 Hint

Common Mistakes

Setting minimum capacity to 0 disables running tasks.

Using a very high minimum capacity unnecessarily.

The minimum capacity for ECS service auto scaling should be set to a positive integer like 1 to ensure at least one task is running.

medium

Complete the code to define the maximum number of tasks for ECS service auto scaling.

AWS

MaxCapacity: [1]

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

💡 Hint

Common Mistakes

Setting maximum capacity lower than minimum capacity.

Setting maximum capacity to zero disables scaling.

The maximum capacity defines the upper limit of tasks the ECS service can scale to. Setting it to 10 allows scaling up to 10 tasks.

Fix the error in the target tracking scaling policy configuration by completing the missing value.

💡 Hint

Common Mistakes

Setting target value to 0 disables scaling triggers.

Setting target value too high causes insufficient scaling.

The target value for CPU utilization in ECS auto scaling is commonly set to 75% to balance performance and cost.

4fill in blank

hard

Fill both blanks to configure the scalable target resource ID and scalable dimension for ECS service auto scaling.

AWS

ResourceId: [1]
ScalableDimension: [2]

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

Aservice/myCluster/myService

Bservice/myCluster/anotherService

💡 Hint

Common Mistakes

Using incorrect resource ID format.

Using wrong scalable dimension like ecs:task:Count.

The resource ID must specify the ECS service in the format 'service/clusterName/serviceName'. The scalable dimension for ECS service desired count is 'ecs:service:DesiredCount'.

5fill in blank

hard

Fill all three blanks to complete the CloudFormation snippet for ECS service auto scaling target and policy.

AWS

AutoScalingTarget:
  MinCapacity: [1]
  MaxCapacity: [2]
  ResourceId: [3]

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

💡 Hint

Common Mistakes

Setting MinCapacity higher than MaxCapacity.

Incorrect ResourceId format.

MinCapacity is set to 2 to keep at least two tasks running. MaxCapacity is 10 to allow scaling up. ResourceId specifies the ECS service path.
