AWS CloudWatch logs in multiple regions

Question

I created a lambda function in us-east-1 and sns topic to send notifications to a slack channel.

Now I also want to use logs from a service in us-west-2 to trigger the notifications but I can't because they are in different regions.

Whats the best way to handle this? I could just copy the Lambda function/sns topic into us-west-2 but that seems redundant....

Thanks

Answer 1

I decided to go with separate lambda functions in each region.

Since Network Manager is only available in US West 2 and the messages being processed will be specific to that region.
