To successfully deploy application revisions in AWS CodeDeploy for EC2/on-premise instances, the first step is to create an application within CodeDeploy. This application serves as a logical grouping for the deployments. Next, a deployment group is specified, which organizes the instances targeted for the deployment and can include settings like tags or Auto Scaling groups. Following that, the deployment configuration is defined, which outlines how the deployment should be carried out, such as whether it should be a "blue/green" or "in-place" deployment. Finally, you upload the revision of the application code, typically in the form of a ZIP or TAR file that contains the application files and the AppSpec file, which defines how the application should be deployed.

The other options do not accurately reflect the procedure for deploying applications using AWS CodeDeploy. They either include components irrelevant to the CodeDeploy service or omit crucial steps necessary for the deployment process. For example, defining a service and creating a target group are more aligned with Amazon ECS or Elastic Load Balancing rather than CodeDeploy.
