Costs

Pitt-Google Broker makes astronomy data available in Google Cloud services like Pub/Sub, BigQuery, and Cloud Storage. Google provides a baseline level of access for free with no credit card or billing account required. The free tier is structured as a usage quota that renews monthly. Access beyond the free tier is “pay-as-you-go”. Some examples are given in the table below. If you exceed the free-tier quota and have not set up billing, your access will be restricted until the quota renews.

Pricing Examples (as of Aug. 2021)

Service	Activity	Free Tier quota	Price beyond Free Tier
BigQuery	querying data	1 TB per month	$5.00 per TB
Pub/Sub	message delivery	10 GB per month	$40 per TB
