Explanation

Virtual warehouses are clusters of compute resources in Snowflake's multi-cluster shared data architecture. Their primary responsibility is executing queries - they load data from storage into memory and perform the actual computation for DML and SELECT operations. Infrastructure management and metadata management are handled by Snowflake's cloud services layer. Query parsing and optimization are also handled by the cloud services layer. Permanent storage of micro-partitions is handled by Snowflake's centralized storage layer, not virtual warehouses.
