This is a data warehouse offered as SaaS (software as a service). This means that users do not need to select, install, configure, or manage hardware, nor do they need to install, configure, or manage software. Maintenance, management, and configuration are handled entirely by Snowflake.
All components run on a public cloud infrastructure. Calculations are performed on virtual instances, and data storage is provided by Snowflake's storage service.
This Cloud Data Warehouse is not based on an existing database or software platform such as Hadoop, but on a new SQL database engine based on an architecture specifically designed for the Cloud.
