You've set up a continuous delivery service using AWS CodePipeline, which automates the steps for deploying your application. The pipeline is configured to use your source code stored in a CodeCommit repository, builds it using AWS CodeBuild, and deploys it with AWS Elastic Beanstalk. Every time you commit changes, this setup triggers an automatic deployment. However, you are experiencing prolonged deployment times specifically because resolving dependencies on your 100 target EC2 instances is taking a significant amount of time.

What could you do to improve the performance of this deployment process with minimal modifications to your existing code?
