Snowflake vs Redshift

Snowflake and Redshift are the most widely compared cloud data warehouses. Snowflake pioneered the separation of compute and storage; Redshift has rapidly evolved to compete.

Architecture Differences

Snowflake's three-layer architecture (cloud services, compute, storage) allows fully independent scaling. Virtual warehouses can be created, resized, and destroyed in seconds. Multi-cluster warehouses automatically add compute for concurrent query spikes.

Redshift's traditional architecture ties compute and storage together in nodes, though Redshift Managed Storage (RA3 nodes) now decouples them somewhat. Redshift Serverless provides auto-scaling but is architecturally different from Snowflake's native approach.

Performance Characteristics

Snowflake requires minimal tuning: micro-partitioning happens automatically, and the query optimizer handles most optimization. Redshift delivers excellent performance when properly tuned with appropriate distribution keys, sort keys, and compression encodings.

For teams without dedicated data engineering resources, Snowflake's automatic optimization is a significant productivity advantage. For teams willing to invest in tuning, Redshift can match or exceed Snowflake's performance.

Trade-offs

Snowflake's multi-cloud support is its strongest differentiator. Running on AWS, Azure, and GCP allows organizations to avoid cloud lock-in and enable cross-cloud data sharing. Redshift is AWS-only.

Snowflake's Data Marketplace creates a network effect: access third-party datasets, share data securely with partners, and monetize your own data. Redshift's data sharing is limited to within AWS accounts.

Cost Optimization

Snowflake's credit-based pricing with per-second billing and auto-suspend minimizes waste. Redshift's reserved instances offer up to 75% savings for committed capacity. For cost-conscious data platform design, the optimal choice depends on workload predictability.

Real-World Usage

Snowflake powers Capital One, Adobe, and NBC Universal. Redshift serves Netflix, Nasdaq, and McDonald's. Market momentum has favored Snowflake, but Redshift's rapid innovation keeps it competitive.
