Summary
We are thrilled to announce that Powertools for AWS Lambda (Python) now offers AWS Lambda layers in the AWS China region cn-north-1.
New AWS China Lambda Layer ARNs
You can now use Powertools for AWS Lambda (Python) Lambda layers in the AWS China regions, enhancing customer experience by making our pre-packaged Lambda layers available in this AWS partition.
To take advantage of the new layers, you need to update your functions or deployment setup to include one of the new Lambda layer ARN from the table below:
AWS China (cn-north-1)
| Architecture | Layer ARN |
|---|---|
| x86_64 | arn:aws-cn:lambda:cn-north-1:498634801083:layer:AWSLambdaPowertoolsPythonV3-{python_version}-x86_64:{version} |
| ARM | arn:aws-cn:lambda:cn-north-1:498634801083:layer:AWSLambdaPowertoolsPythonV3-{python_version}-arm64:{version} |
