How to find out current region with AWS Lambda

Question

I have a AWS Lambda function written in Java. I want to know if there is a way to find out the AWS region I am currently using through this Lambda function. 

Note: Tried Regions.getCurrentRegion(). It returns null from within an AWS Lambda function.

Answer 1

You can read the AWS_DEFAULT_REGION environment variable and use the Regions.fromNamefunction to parse that into a useable region. The advantage of this is you can use it outside your handler function.

Regions.fromName(System.getenv("AWS_DEFAULT_REGION"))
