If 2M requests result in 1 Gb network traffic, each message is 500 bits (~60 bytes). Theoretically, that's 1K messages per batch. Even if practically that number is much lower (around 100 per batch), the cost ends up becoming around $3,000 for the messages and $9,000 for the network, so roughly $12,000 per month.
