Short version: does each Application on TTN require a separate AWS Integration instance?
I have added another application to my (Community) console and I am receiving messages. I already have an existing application that connects to an AWS IoT integration and it is working perfectly. I need to add the new application to AWS IoT but I am not clear whether it is necessary to create an entirely new AWS integration instance for this new application, or if I can use the same CloudFormation stack and Role ARN with both applications simultaneously.
Since the integration is responsible for creating and deleting AWS IoT objects (for each end node on TTN) I thought there might be a conflict if two separate TTN Applications access the same AWS Integration instance. If, however, the AWS integration is “smart enough” to manage multiple TTN Applications then a second instance is not necessary.
