# Stop hardcoding AWS Lambda layer ARNs, and use AWS Systems Manager Parameter Store public parameters instead
A recent DEV Community article, titled "Stop hardcoding AWS Lambda layer ARNs, and use AWS Systems Manager Parameter Store public parameters instead," recommends that developers avoid hardcoding AWS Lambda layer ARNs in their code and configurations. The author argues that using AWS Systems Manager Parameter Store public parameters offers a more flexible and maintainable solution. The article likely explains how to retrieve layer ARNs dynamically from Parameter Store, which can simplify updates and reduce the risk of errors from outdated hardcoded values. The post is part of a themed challenge on DEV Community, indicated by the '418challenge' tag, which may influence its presentation but not its technical content. The recommendation is aimed at AWS developers looking to improve their serverless workflows.
Using Parameter Store public parameters for Lambda layer ARNs reduces maintenance overhead and errors from hardcoded values.
