Zorluk: OrtaDeployment Strategies

A developer needs to deploy a new version of an application to an active AWS Elastic Beanstalk environment. The application must maintain 100% of its instance capacity to handle traffic during the deployment process. The deployment must be completed within the existing environment without creating a second, separate Elastic Beanstalk environment. Which two deployment strategies will meet these requirements? (Select two.)

  1. Rolling with additional batchCevap
  2. ImmutableCevap
  3. C
    Rolling
  4. D
    All at once
  5. E
    Blue/Green (Environment Swap)

Cevap

The correct strategies are 'Rolling with additional batch' and 'Immutable' because they both maintain full capacity throughout the deployment process and run entirely within the existing Elastic Beanstalk environment.
The correct strategies are the 'Rolling with additional batch' and 'Immutable' deployment strategies. The 'Rolling with additional batch' strategy launches a temporary batch of instances first, ensuring that the environment's capacity never drops below 100% during the rolling update. The 'Immutable' strategy launches a full set of new instances in a temporary Auto Scaling group, ensuring full capacity is maintained, and performs a clean switchover within the existing environment once health checks pass.

Adım Adım Çözüm

1
Analyze the capacity requirement
The application must maintain 100% capacity. This rules out standard 'Rolling' (which reduces capacity by the batch size) and 'All at once' (which takes all instances offline).
Determining which deployment strategies preserve capacity.
2
Analyze the environment boundary constraint
The deployment must occur within the existing environment. This rules out 'Blue/Green (Environment Swap)' because it requires provisioning a new, separate Elastic Beanstalk environment.
Filtering out strategies that require multiple environments.
3
Identify matching strategies
'Rolling with additional batch' and 'Immutable' both run in the existing environment, provision temporary instances to maintain 100% capacity, and clean up the extra instances afterward.
Selecting the remaining compliant strategies.
