• 2,250,000 minutes of connection
• 500,000 messages
• 225,000 Registry or Device Shadow operations
• 250,000 rules triggered and 250,000 actions executed

For example, the Free Tier would allow you to run a 50-device workload, where each device:

• Connects for 24 hours a day
• Exchanges 300 messages per day (message size 5 KB or smaller)
• Makes 130 Registry or Device Shadow operations per day (Registry or Device Shadow record size 1 KB or smaller)
• Triggers 150 rule executions per day that invoke one action (processed message size 5 KB or smaller)

The AWS Free Tier is available to you for 12 months starting with the date on which you create your AWS account. When your free usage expires or if your application use exceeds the free usage tiers, you simply pay the above rates. The free usage tier applies across all AWS Regions except GovCloud (US). Your usage is calculated each month across all regions and is automatically applied to your bill. Note that free usage does not accumulate from one billing period to the next.
