Snowflake

Snowflake is a cloud data platform, commonly described as the AI Data Cloud, that allows organisations to store, process, analyse and share data at virtually any scale. Founded in 2012 and headquartered in Bozeman, Montana, the company pioneered a cloud-native architecture that separates storage from compute, so that multiple teams and workloads can access the same data concurrently without contending for resources. This design addresses long-standing limitations of traditional on-premises data warehouses, which required costly capacity planning, struggled with concurrency and made it difficult to share data securely across departments or with external partners.

Snowflake runs on Amazon Web Services, Microsoft Azure and Google Cloud, and its cross-cloud layer enables replication and data sharing between regions and providers. Virtual warehouses provide elastic, independently scalable compute that can be started, resized and suspended automatically, with consumption-based billing for compute and storage. The platform handles structured and semi-structured data such as JSON, Avro and Parquet, supports Apache Iceberg tables, and includes features for data engineering, including Snowpipe for continuous ingestion, streams and tasks for pipelines, and dynamic tables. Snowpark allows developers to write transformations and machine learning code in Python, Java and Scala that executes inside Snowflake, while Snowflake Cortex provides access to large language models, vector search and AI functions directly on governed data. Secure data sharing and the Snowflake Marketplace let organisations publish and consume live datasets and applications without copying data, and Native Apps extend this to packaged software. Governance capabilities cover role-based access control, dynamic data masking, row-level policies, object tagging, lineage and the Horizon catalogue. Snowflake integrates with a broad ecosystem of BI, ETL, data science and reverse ETL tools. It is used by enterprises and digital-native companies across financial services, retail, healthcare, media, technology and the public sector for data warehousing, data lakes, analytics and AI workloads. Pricing starts from around USD 23 with a free trial; there is no permanently free version, and costs scale with consumption.
