Pricing Example 1
A blog application has 50,000 monthly active users that each perform 100 searches. These searches generate 5,000,000 AppSync query operations per month, with an average response size of 3 kilobytes (KB).
|Query operation charges||5 million x $4.00 per million operations= $20.00|
|Data transfer charges||3 KB x 5 million = 15 million KB = 14.3 GB * $0.09 = $1.29|
|Total AppSync charges||$20.00 + $1.29 = $21.29|
Pricing Example 2
A chat application has 2,500 monthly active users. Each user has the app open for an average 1,500 minutes per month, posts 1,000 messages per month, and receives 1,000 messages per month from other users. This results in 2,500,000 data modification operations per month and 2,500,000 real-time updates per month.
|Data modification operation charges||2,500 users x 1,000 sent messages x $4.00 per million operations = $10.00|
|Data transfer charges||1KB X 2.5 million – 2.5 million KB = 2.4GB X $0.09 = $0.21|
|Real-time update charges||2,500 users X 1,000 received messages X $2.00 per million updates = $5.00|
|Connectivity charges||2,500 clients x 1,500 minutes x $0.08 per million connection-minutes = $0.30|
|Total AppSync charges||$10.00 + $0.21 + $5.00 + $0.30 = $15.51|
