Python boto3- How to work on cross region

Question

I started writing my lambda function using python and boto3,

I managed to work on every region separately but I didn't see how I can work in a few regions together.

This is how I announce my client:

region= 'ap-southeast-2'
ec2 = boto3.client('ec2', region_name=region)

If I do not give it a region it will run on the region you created your lambda function on, which is something I don't want.

Did anyone did it before?

Answer 1

If you do not give it a region it will use the region your Lambda function is running in.

If you want to make AWS API calls in multiple regions via Boto3 you will have to create a client object for each region, and make separate API calls for each region.
