AWS Certified Developer Associate DVA-C02 Practice Question

The best method to manage shared dependencies in serverless functions is to utilize Layers. By doing so, developers can deploy common libraries and dependencies as a distinct layer that multiple functions can then reference. This approach centralizes dependency management and decreases the size of each function's deployment package, simplifying updates and maintenance. Adding shared dependencies directly to each function’s deployment package unnecessarily increases the size of the packages, which can result in longer deployment times and challenges in maintaining consistency across functions. Rebuilding the entire application for shared dependency updates is both inefficient and not directly related to the deployment of the serverless functions. Using a configuration management service like AppConfig is not suitable for code dependencies, as its purpose is adjusting application behavior without requiring code updates.
