AWS SNS定价

Question

I have some questions about AWS SNS pricing.

https://aws.amazon.com/sns/pricing/

Includes publish, topic owner operations, and subscriber operations, but not deliveries

I am sending push notification to device.

1. Is it counted as 2 operations? Sending + deleivery?

Includes publish, topic owner operations, and subscriber operations , but not deliveries

2. Get or list are counted as operations?

I am registering device. This is one operation. Now I am recreating device registration, but it has same token, so new endpoint is not created.

3. Is it counted as operation? Same for subscriptions? Same for topics?

I have 5 device endpoints, all of them are subscribed to one topic. Now I am sending message to the topic.

4. How many operations does it cost me? 6 (1 sending + 5 delivery)? 10 (5 sending + 5 delivery)? Another number?

I have 5 device endpoints, all of them are subscribed to one topic. 4 of them are disabled. I am sending message to the topic.

5. How many operations does it cost me?
6. Am paying something for storage of disabled device endpoints? Or should I clean them? Does delete endpoint counted as operation?

** Operation = operation that costs money

Answer 1

Every API call is one operation . (My assumption, but that's the norm.)

You will be charged the delivery charge for each enabled subscriber to a topic when a message is sent to the topic. That is, every time that Amazon SNS is expected to delivery a message to one recipient.
