Explanation
Snowflake's architecture is divided into three main layers: Cloud Services, Query Processing (virtual warehouses), and Database Storage. The Database Storage layer is responsible for persisting all data loaded into Snowflake. When data is ingested, Snowflake automatically reorganizes it into its proprietary internal format - optimized, compressed, and columnar - and stores it in cloud object storage (e.g., S3, Azure Blob, GCS). Users never interact directly with the underlying files; Snowflake manages all storage organization transparently. Cloud Services handles authentication, metadata, and query optimization, while Query Processing executes the actual compute workloads.
