Usage of retention	Assuming 100% retention of data and an average event size of 2 KiB over 30 days (5 GiB), and when charged US$0.50 per GiB, the charge is US$2.50.
Total charge	US$7.50 per month

Eventarc Standard pricing

The total Eventarc Standard billable charge is the combined charge of Eventarc and its transport layer, Pub/Sub.

Eventarc Standard billable component	Pricing
The first 50,000 chargeable events in every calendar month	Free
Events from Google sources	US$0 per million events published
Events from Pub/Sub sources	US$0 per million events published
Events from other sources	US$1 per million events published (free while in Preview)

Note the following:

• If you pay in a currency other than USD, the prices listed in your currency on Cloud Platform SKUs apply.
• Usage of the Pub/Sub transport layer is billed at standard Pub/Sub rates.
• For Pub/Sub sources, Eventarc can use the existing Pub/Sub topic used by the event provider when publishing events.
• Events using Cloud Audit Logs incur Cloud Logging charges and event receiver services incur any applicable charges; for example, Cloud Run.
• Events larger than 64 KB are considered multiple events. Each 64 KB portion of a payload is billed as 1 event. For example:
  • 64.001 KB event—2 events billed
  • 257 KB event—5 events billed
  • 512 KB event (maximum event size)—8 events billed

Billing examples

These examples assume events using Cloud Audit Logs are typically 2 KB.

Google event source example

Scenario: A Cloud Run service receiving one 2 KB event every minute for a month (43,200 events) at a rate of 2 KBps from a Google source such as Cloud Storage using Cloud Audit Logs.

Usage of Eventarc	US$0 per million events published for 43,200 events. The charge is US$0.
Usage of the Pub/Sub transport layer	Assuming one Pub/Sub topic with one subscription and the subscriber is consuming all generated events. Pub/Sub has a total transmission rate of 4 KBps (2 KBps ingress and 2 KBps egress). Over 30 days this is 0.0095 TiB of data. The billable data volume is 0.0095 TiB, and when charged at US$40 per TiB, the charge is US$0.38. However, the free tier of the first 10 GB would reduce the charge to US$0.
Total charge with free tier	US$0 (Eventarc) + US$0 (Pub/Sub) = US$0
Total charge without free tier	US$0 (Eventarc) + US$0.38 (Pub/Sub) = US$0.38

Pub/Sub event source example

Scenario: A Cloud Run service receiving one 512 KB event every second for a month (2,592,000 events) at a rate of 1 MBps from a Pub/Sub source.

Usage of Eventarc	US$0 per million events published for 2,592,000 events. The charge is US$0.
Usage of the Pub/Sub transport layer	Assuming one Pub/Sub topic with one subscription and the subscriber is consuming all generated events. Pub/Sub has a transmission rate of 2 MBps (1 MBps ingress and 1 MBps egress). Over 30 days this is 4.715 TiB of data. The billable data volume is 4.715 TiB, and when charged at US$40 per TiB, the charge is US$188.60. However, the free tier of the first 10GB would reduce the charge to US$188.20.
Total charge with free tier	US$0 (Eventarc) + US$188.20 (Pub/Sub) = US$188.20
Total charge without free tier	US$0 (Eventarc) + US$188.60 (Pub/Sub) = US$188.60
