Introduction to Snowflake

Introduction to Snowflake

Snowflake is a cloud data warehouse service that organizations can use to store and analyze data.
Snowflake is a Software-as-a-Service (SaaS) application that uses an SQL database engine with an architecture designed for the cloud.
The Snowflake architecture comprises the following three layers, which sets Snowflake apart from other data warehouses with its additional functionalities and capabilities:
  • Database Storage. When you load data to Snowflake, Snowflake reorganizes and stores the data in the Snowflake database. You can access the data stored in the Snowflake database through SQL query operations.
  • Query Processing. Snowflake processes all queries in the query processing layer. The processing layer contains all the compute resources that Snowflake needs to run queries. For example, Snowflake uses CPU, memory, and temporary storage to run queries.
  • Cloud Services. The cloud services layer contains all the different components that Snowflake needs to process the user requests. For example, Snowflake uses authentication, infrastructure management, and access control services to process user requests.
