Snowflake’s Expansion: Bringing Cloud Advantages to On-Premises Data

Snowflake’s cloud-native architecture has disrupted the data warehousing world. Its storage and compute layer separation, near-infinite scalability, and pay-as-you-go model have been game-changers. However, Snowflake’s fully cloud-based design historically presented limitations for organizations bound by strict data residency regulations or those reluctant to transition fully to the cloud. Snowflake is addressing this with strategic advancements in hybrid capabilities.

The Evolution of Snowflake: From Cloud-Only to Hybrid

Until recently, Snowflake required all data to be stored within its cloud infrastructure. That’s changing. Here’s why and how:

• Understanding the Need: Security and compliance are paramount for many companies. Regulations like GDPR, healthcare privacy laws, and industry-specific standards often mandate that sensitive data remain on-premises. Additionally, some organizations prefer maintaining local control over core datasets.
• Snowflake’s Response: Snowflake recently introduced the ability to work with on-premises data using External Stages and External Tables. This lets organizations query their existing on-premises data lakes directly from Snowflake without any data movement.

Critical Use Cases for Snowflake with On-Premises Data

1. Hybrid Data Warehousing: Snowflake can now be the centralized analytics platform for your cloud-based and on-premises datasets. Analyze everything in one place, regardless of storage location.
2. Gradual Cloud Migration: Not ready for a complete cloud leap? Start by analyzing existing on-premises data with Snowflake. This “test drive” lets you experience Snowflake’s benefits before committing to a full migration.
3. Data Lake Analytics: If you have an S3-compatible on-premises data lake (like Cloudian HyperStore), you can query and analyze JSON, Parquet, ORC, and Avro files with Snowflake, enjoying the processing power and governance Snowflake provides.
4. Joining Cloud and On-Premises Data: Enrich your analytics! You can now quickly join cloud datasets with on-premises ones within Snowflake.

Benefits of Snowflake’s Hybrid Approach

• Flexibility: Snowflake becomes more adaptable, meeting the needs of a broader range of organizations bound by data location requirements.
• Centralized Control: Get a holistic view of both cloud-based and on-premises data. Snowflake’s governance, security, and user management tools apply even when accessing data on-premises.
• Faster Insights: Unlock new insights by combining traditionally disparate data stores without the complexity of data replication.

Things to Note

• This functionality is evolving, so expect improvements and expanded capabilities over time.
• Performance may vary depending on network connectivity between your Snowflake instance and the on-premises data.
• Additional configuration may be required for on-premises systems to expose data in a format compatible with Snowflake.

The Future of Snowflake and On-Premises

Snowflake’s inclusion of on-premises data marks a significant turning point. It opens up possibilities for organizations that couldn’t previously consider its powerful features. The future likely holds continued innovation in hybrid solutions, making Snowflake an even more compelling choice for a broader range of enterprises.
