Difficulty: MediumDeployment Strategies

A developer is configuring a blue/green deployment for an Amazon Elastic Container Service (Amazon ECS) service using AWS CodeDeploy. The deployment must shift traffic to the new task set gradually to allow for monitoring, but the entire deployment process must finish shifting 100%100\% of the traffic in less than 1010 minutes.

Which TWO predefined deployment configurations will meet these requirements? (Select TWO.)

  1. CodeDeployDefault.ECSLinear10PercentEvery1MinuteAnswer
  2. CodeDeployDefault.ECSCanary10Percent5MinutesAnswer
  3. C
    CodeDeployDefault.ECSLinear10PercentEvery3Minutes
  4. D
    CodeDeployDefault.ECSCanary10Percent15Minutes
  5. E
    CodeDeployDefault.ECSAllAtOnce

Answer

The configurations CodeDeployDefault.ECSLinear10PercentEvery1Minute and CodeDeployDefault.ECSCanary10Percent5Minutes meet the requirements.
The correct configurations are CodeDeployDefault.ECSLinear10PercentEvery1Minute and CodeDeployDefault.ECSCanary10Percent5Minutes. The linear configuration shifts 10%10\% of traffic each minute, completing the transition in 99 minutes. The canary configuration shifts 10%10\% first, waits 55 minutes, and then shifts the remaining 90%90\%, completing the transition in 55 minutes. Both configurations satisfy the requirements of shifting traffic gradually and completing the deployment in less than 1010 minutes.

Step-by-Step Solution

1
Analyze the requirement to shift traffic gradually.
Discard the all-at-once configuration since it shifts traffic immediately and does not allow for gradual transition or monitoring.
Gradual shifting is a strict constraint specified in the prompt.
2
Calculate the total traffic shifting duration for each remaining configuration.
The 1-minute linear configuration takes 99 minutes, the 5-minute canary configuration takes 55 minutes, the 3-minute linear configuration takes 2727 minutes, and the 15-minute canary configuration takes 1515 minutes.
This determines which configurations complete within the required 10-minute window.
3
Select the configurations that meet the duration constraint.
The 1-minute linear configuration and the 5-minute canary configuration both complete in less than 1010 minutes.
Only these two configurations satisfy both the gradual shifting and the time constraint of less than 10 minutes.
