SNS send same push notification to millions of user synchronously

Question

I have created a platform application and have multiple application endpoints in it.
I have to send a push notification to all of the application endpoints in a go(simultaneously). I don't want to publish to each endpoint one by one, is there any way to do so?

Answer

Just [subscribe](https://docs.aws.amazon.com/sns/latest/dg/sns-create-subscribe-endpoint-to-topic.html) those endpoints to a topic and [publish to the topic](https://docs.aws.amazon.com/sns/latest/dg/mobile-push-send-topicmobile.html).
