I have a requirement where my application, in AWS account A, needs to broadcast that a new resource is created, to AWS accounts: B, C and D.
I was thinking of implementing a solution, where an SNS Topic in Account A, publishes to SQS Queues Accounts: B, C and D (FanOut Pattern).
Question: Is it possible to use SNS Topics in account B, C and D rather than SQS Queues?
Basically, is it possible to subscribe one SNS Topic to another?
I was not able to find anything that concretely answered the question.
>Solution :
No. Amazon SNS is not an available subscription type.
You could subscribe an AWS Lambda function and that Lambda function could send messages to desired SNS topics.
