Cevap

The Immutable and Rolling with additional batch deployment policies both ensure that capacity is never reduced during the update.
The Immutable and Rolling with additional batch deployment policies both maintain 100%100\% of the environment's provisioned capacity during an update. Immutable launches a temporary Auto Scaling group to deploy the new version, while Rolling with additional batch launches an extra batch of instances before updating existing ones. In both cases, the existing healthy capacity is never reduced.

Adım Adım Çözüm

1
Analyze the capacity requirement during deployment
The application requires 100%100\% of its provisioned capacity to be active at all times.
To prevent performance degradation during the update process.
2
Evaluate in-environment Elastic Beanstalk deployment policies
Immutable deployment deploys to a new temporary Auto Scaling group before switching, and Rolling with additional batch launches an extra batch of instances before updating existing ones. Both keep existing instances fully operational.
To select the strategies that do not take existing capacity offline without replacement.
