Hi Everyone, I am new to Pulumi AWS using python , wanted to understand how to manage same stack let say dev and create and update resources for different regions ? is it even possible or i need to create stack for each aws region ?

You can manage stacks in multiple AWS regions inside a single stack by using explicit resource providers: https://www.pulumi.com/docs/concepts/resources/providers/#explicit-provider-configuration

Thanks @white-balloon-205 will try this out for our use case,

I would recommend to split into different stacks, this will allow you to test changes on one region before commiting to all
