Event buses
Amazon Web Services Free Tier: Amazon Web Services management events are ingested by the event bus for free.
The EventBridge Event Bus can receive events from Amazon Web Services services, SaaS partners (“partner events”), or from your own applications (“custom events”). Over 250 Amazon Web Services services automatically send events to the event bus, providing visibility into management operations that are performed on resources in your Amazon Web Services account (“Amazon Web Services management events”). Management operations are also known as control plane operations. Some Amazon Web Services services, such as S3, can send data plane events to the event bus after you opt-in (“Amazon Web Services opt-in data events”).
| Ingestion charges | |
| Amazon Web Services management events | Free |
| Amazon Web Services opt-in data events, custom events, partner events | ¥ 6.75/million events |
| Delivery charges | |
| To another event bus | ¥ 6.75/million events |
| To a service in the same account | Free |
| To a service in a different account | ¥ 0.34/million events, except for Amazon Web Services management events, which are priced at ¥ 6.75/million events |
Size of payloads: Each 64 KB chunk of a payload is billed as one event (for example, an event with a 256 KB payload is billed as 4 events).
There is no additional charge for global endpoints. Custom events published to the global endpoint are billed according to the custom events pricing above.
Pricing example
If you deliver 5 million Amazon Web Services management events to a service in a different account in one month, your charges would be calculated as follows:
Monthly Amazon Web Services management events ingested = 5M events (all equal to or less than 64 KB each)
Monthly ingestion charge = 5M * ¥ 0.00/M = ¥ 0.00 per month
Monthly Amazon Web Services management events delivered to a service in a different account = 5M events (all equal to or less than 64KB each)
Monthly delivery charge = 5M * ¥ 6.75/M = ¥ 33.75 per month
Total monthly EventBridge charges = ¥ 33.75 / month
If your SaaS application publishes 5 million events in one month and you send 1 million of those events to a service in a different account, your charges would be calculated as follows:
Monthly partner events ingested = 5M events (all equal to or less than 64 KB each)
Monthly ingestion charge = 5M * ¥ 6.75/M = ¥ 33.75 per month
Monthly partner events delivered to a service in a different account = 1M events (all equal to or less than 64 KB each)
Monthly delivery charge = 1M * ¥ 0.34/M = ¥ 0.34/M per month
Total monthly EventBridge charges = ¥ 34.09 / month
If you publish 10 million of your own events to an event bus in Account A in one month, send 5 million of those events to another event bus in Account B, and then send those events to another service in Account B, your charges would be calculated as follows:
Monthly custom events ingested = 10M events (all equal to or less than 64 KB each)
Monthly ingestion charge = 10M * ¥ 6.75/M = ¥ 67.50 per month
Monthly custom events delivered to another event bus = 5M events (all equal to or less than 64 KB each)
Monthly custom events delivered to a service in the same account = 5M events (all equal to or less than 64KB each)
Monthly delivery charge = (5M * ¥ 6.75/M) + (5M * ¥ 0.00/M) = ¥ 33.75 per month
Total monthly EventBridge charges = ¥ 101.25 / month
API Destinations
API Destinations allows you to send events from EventBridge event bus to any web based application.
China (Beijing)
¥ 3.10 per million invocations for authentication and security.
China (Ningxia)
¥ 3.52 per million invocations for authentication and security.
Size of payload: Each 64 KB chunk of a payload is billed as 1 event (for example, an event with a 256 KB payload is billed as 4 requests). You may incur additional data transfer charges for data out to the internet. You will be billed at standard Amazon Web Services Data Transfer Charges.
Pricing example
If you invoke 2 million events in one month from your EventBus endpoint to a HTTP endpoint in Amazon Web Services China (Beijing) region, your charges would be as follows:
Monthly events = 2M events
Monthly API Destination charges = 2M * ¥ 3.10/M = ¥ 6.20 per month
Pipes
Amazon EventBridge Pipes helps you create point-to-point integrations between event producers and consumers with optional transform, filter and enrich steps.
| Request, after filtering | ¥ 2.90 / million requests entering a Pipe |
Size of payload: Each 64 KB chunk of payload is billed as one request. For example, a batch of events with a 256 KB payload is billed as four requests.
Pricing example
If your source Amazon Simple Queue Service (SQS) queue receives 10 million events in one month, you apply a filter that matches 25% of your records, and you batch five events per request, your charges for sending those matching records to a target would be as follows:
Usage:
Monthly requests sent = 10,000,000 * 25% / 5 = 500,000
Requests after filtering = 500,000
Charges:
Requests after filtering = 0.5M * ¥ 2.90 = ¥ 1.45
Total monthly EventBridge charges = ¥ 1.45
Event replay
| Archive processing | ¥ 2.47 per GB |
| Storage / Month | ¥ 0.195 per GB / Month |
For replay, you are billed as per the custom events pricing above.
Pricing example
If your application published 2 million events in a month, each averaging 6 KB, and you enabled archiving on your development event bus for replay and you replay all of them, your charges would be calculated as follows:
Monthly events = 2M events * ¥ 6.75/M = ¥ 13.50 per month.
Archive Processing = 2M events * 6KB / (1024 * 1024) * ¥ 2.47/GB = ¥ 28.27
Storage Costs = 2M events * 6KB / (1024*1024) * ¥ 0.195/GB = ¥ 2.23 per month
Replayed Events = 2M * ¥ 6.75/M = ¥ 13.50 per month
Total monthly EventBridge charges = ¥ 13.50 (event publishing) + ¥ 28.27 (Archive Processing) + ¥ 2.23 (Storage) + ¥ 13.50 (Replaying) = ¥ 57.50 per month.
Schema Registry
Free tier: Usage of the Schema Registry for Amazon Web Services services schemas and custom schemas is free. The Schema Discovery feature is free for the first 5 million ingested events per month. Some applications may be able to operate within the Free Tier.
Schema Discovery: ¥ 1.04 / million events ingested for discovery, after 5 million free events ingested per month
Size of payloads: Each 8 KB chunk of a Schema Discovery payload is billed as one ingested event (for example, an event with a 16 KB payload is billed as two ingested events).
Pricing example
If your development environment published 2 million events in a month, each averaging 2 KB, and you enabled Schema Discovery on your development event bus, your charges would be calculated as follows:
Monthly events = 2M events * ¥ 6.75/M = ¥ 13.50 per month
Schema Registry = Free
Schema Discovery = 2M events. No additional discovery costs (5M events included in Free Tier)
Total monthly EventBridge charges = ¥ 13.50 (event publishing) + ¥ 0 Schema Registry + ¥ 0 Schema Discovery = ¥ 13.50 per month
