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.

CodePudding user response：

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.
