A company experienced partial downtime during the last deployment of a new application. AWS Elastic Beanstalk split the environment’s Amazon EC2 instances into batches and deployed a new version one batch at a time after taking them out of service. Therefore, full capacity was not maintained during deployment.
The developer plans to release a new version of the application, and is looking for a policy that will maintain full capacity and minimize the impact of the failed deployment.
Which deployment policy should the developer use?
A . Immutable
B . All at Once
C . Rolling
