For Snowflake, we had four main use cases. The first use case was related to a data warehouse, and my banking client wanted to move his SQL Server database to Snowflake. All the source systems were also on Oracle and file-based systems, and the target data warehouse was SQL Server. From SQL Server, the client wanted to move to Snowflake.
The second use case was related to a chat or messaging client. They were using EMR Hadoop as their data warehouse, but it was not performing, so we had to move the EMR Hadoop to Snowflake.
The third use case was related to a ServiceNow compliance system, where ServiceNow was using SAP HANA for its reporting data warehouse, but it was too slow. It was not performing, and it was causing a lot of problems. We moved that ServiceNow compliance system from SAP HANA to Snowflake.
The fourth use case was related to a huge SQL Server database for a banking client. We moved the entire SQL database to Snowflake.
