The ways that Company A can share data with Company B are:

Create a share within Company A’s account and add Company B’s account as a recipient of that share: This is a valid way to share data between different accounts on different cloud platforms and regions. Snowflake supports cross-cloud and cross-region data sharing, which allows users to create shares and grant access to other accounts regardless of their cloud platform or region. However, this option may incur additional costs for network transfer and storage replication.

Create a separate database within Company A’s account to contain only those data sets they wish to share with Company B Create a share within Company A’saccount and add all the objects within this separate database to the share Add Company B’s account as a recipient of the share: This is also a valid way to share data between different accounts on different cloud platforms and regions. This option is similar to the previous one, except that it uses a separate database to isolate the data sets that need to be shared. This can improve security and manageability of the shared data. The other options are not valid because:

Create a share within Company A’s account, and create a reader account that is a recipient of the share Grant Company B access to the reader account: This option is not valid because reader accounts are not supported for cross-cloud or cross-region data sharing. Reader accounts are Snowflake accounts that can only consume data from shares created by their provider account. Reader accounts must be on the same cloud platform and region as their provider account.

Use database replication to replicate Company A’s data into Company B’s account Create a share within Company B’s account and grant users within Company B’s account access to the share: This option is not valid because database replication cannot be used for cross-cloud or cross-region data sharing. Database replication is a feature in Snowflake that allows users to copy databases across accounts within the same cloud platform and region. Database replication cannot copy databases across different cloud platforms or regions.

Create a new account within Company A’s organization in the same cloud provider and region as Company B’s account Use database replication to replicate Company A’s data to the new account Create a share within the new account and add Company B’s account as a recipient of that share: This option is not valid because it involves creating a new account within Company A’s organization, which may not be feasible or desirable for Company A. Moreover, this option is unnecessary, as Company A can directly share data with Company B without creating an intermediate account.
