How do you size a data warehouse?

Storage = raw data size / compression ratio (typically 3-10x for columnar). Compute depends on concurrent query users and query complexity. Snowflake: XS warehouse (1 credit/hr) handles 2-5 concurrent medium queries. Scale up for > 10 concurrent users or > 1 TB scans per query.

How does Snowflake credit pricing work?

Snowflake credits: XS = 1 credit/hr, S = 2, M = 4, L = 8, XL = 16. Standard edition: $2-3 per credit. Enterprise: $3-4 per credit. A 1 XS warehouse running 8 hours per day = 8 credits = $16-$24/day. Auto-suspend after 60 seconds of inactivity is critical for cost control.
