Lambda Layer

Lambda-layer and lambda-layer-version in Amazon Web Services (AWS) are closely linked, as they both play a critical role in the efficient deployment of serverless applications. Lambda-layers are packages of code, libraries, and other dependencies that can be used across multiple AWS Lambda functions. This functionality allows developers to reduce code duplication and prevents the need for complex versioning strategies. By using a single layer, developers can make changes to the underlying resources without having to update each individual function. Lambda-layer-versions represent specific instances of layers that have been published. An up-to-date version of the layer is created whenever changes are made to its contents or configuration settings, allowing developers to deploy new versions with minimal effort and keep track of their progress over time. These versions can also be deployed independently from any functions that may be relying on them, allowing for more granular control over deployments and updates.
