Snowflake is provided as Software-as-a-Service (SaaS) that runs completely on cloud infrastructure. This means that all three layers of Snowflake’s architecture (storage, compute, and services) are deployed and managed entirely on a selected cloud platform.
A Snowflake account can be hosted on either of the following cloud platforms:
If your organization’s other cloud services are already hosted on either AWS or Microsoft Azure, your choice of platform can be straightforward (i.e. your Snowflake accounts can all be hosted on the same platform).
However, the platform you choose for each Snowflake account is completely independent from your other Snowflake accounts. In fact, you can choose to host each Snowflake account on a different platform, although this may have some impact on data transfer billing when loading data.
In this Topic:
Differences in unit costs for credits and data storage are calculated by geographical region and not by cloud platform. For more information about pricing as it pertains to a specific region, see the pricing page (in the Snowflake website).
Snowflake supports loading data from files staged in any of the following locations regardless of the cloud platform for your Snowflake account:
- Internal (i.e. Snowflake) stages
- Amazon S3
- Microsoft Azure Blob storage
Snowflake supports both bulk data loading and continuous data loading (Snowpipe). Likewise, Snowflake supports unloading data from tables into any of the above staging locations.

Some data transfer billing charges may apply when loading data from files staged across different platforms. For more information, see Understanding Snowflake Data Transfer Billing.
