In other words, they are a distribution mechanism for artifacts. The layers can be versioned, and each version is immutable. An AWS Lambda layer is a ZIP archive that contains libraries, a custom runtime, or other dependencies. Lambda functions can be configured to reference these layers. The layer is then extracted to the `/opt` directory in the function execution environment. Each runtime looks for libraries in a different location under the `/opt` folder, depending on the language. \ No newline at end of file diff --git a/src/data/roadmaps/aws/content/116-lambda/102-custom-runtimes.md b/src/data/roadmaps/aws/content/116-lambda/102-custom-runtimes.md index 69918f769..3280009bd 100644 --- a/src/data/roadmaps/aws/content/116-lambda/102-custom-runtimes.md +++ b/src/data/roadmaps/aws/content/116-lambda/102-custom-runtimes.md @@ -1 +1,3 @@ -# Custom runtimes \ No newline at end of file +# Custom Runtimes + +AWS Lambda supports several preconfigured runtimes for you to choose from, including Node.js, Java, Ruby, Python, and Go.

This setup process adds to the function's execution time, and is particularly noticeable in situations where low latency is critical. Cold start times also vary based on the memory size, with bigger lambda functions taking longer times to start.
