Answer: CodeDeploy Deployment Groups
Overall explanation Correct option: CodeDeploy Deployment Groups You can specify one or more deployment groups for a CodeDeploy application. The deployment group contains settings and configurations used during the deployment. Most deployment group settings depend on the compute platform used by your application. Some settings, such as rollbacks, triggers, and alarms can be configured for deployment groups for any compute platform. In an EC2/On-Premises deployment, a deployment group is a set of individual instances targeted for deployment. A deployment group contains individually tagged instances, Amazon EC2 instances in Amazon EC2 Auto Scaling groups, or both. Incorrect options: CodeDeploy Agent - The CodeDeploy agent is a software package that, when installed and configured on an instance, makes it possible for that instance to be used in CodeDeploy deployments. The agent connects the EC2 instances to the CodeDeploy service. CodeDeploy Hooks - Hooks are found in the AppSec file used by AWS CodeDeploy to manage deployment. Hooks correspond to lifecycle events such as ApplicationStart, ApplicationStop, etc. to which you can assign a script. Define multiple CodeDeploy Applications - This option has been added as a distractor. Instead, you want to use deployment groups to use the same deployment and maybe separate the times when a group of instances receives the software updates.

As a Site Reliability Engineer (SRE) tasked with enhancing the deployment process through scaling and automation, you play a crucial role in ensuring the seamless release of new application versions into production. To achieve a smooth rollout, it is essential that these new versions are deployed incrementally across different sets of EC2 instances, thereby facilitating a gradual transition and minimizing potential disruptions.
Given the need to deploy application updates to multiple groups of EC2 instances at varying times for a smooth transition, which of the following features in AWS CodeDeploy enables this capability?
A
CodeDeploy Agent
B
CodeDeploy Hooks
C
CodeDeploy Deployment Groups
D
Define multiple CodeDeploy Applications
