Once you have a clear understanding of these aspects, it's essential to look at the unique tech context of Snowflake and BigQuery. In short, three main factors set these two cloud data warehouses apart: cloud environment, ease of use, and scalability. Let's break these aspects down.

Snowflake is a multi-cloud data warehouse solution that runs on top of Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure. This flexibility allows organizations to choose the cloud provider that best fits their needs or even operate across multiple cloud environments.

BigQuery, on the other hand, is a fully managed, serverless data warehouse developed by Google. It is an integral part of the GCP and leverages Google's Dremel technology to enable fast and scalable analytics.

The distinction between these data warehouses becomes more evident when considering their respective target markets and ease of use. Snowflake is designed to cater to organizations of all sizes, offering flexibility and control over resource allocation with its separation of storage and compute resources. This independence allows for fine-grained management of costs and performance tuning.

BigQuery, in contrast, targets businesses that prefer a hands-off approach to resource management. Its serverless architecture abstracts away the underlying infrastructure, allowing users to focus on their data and analytics without worrying about provisioning or scaling resources.

Another point to ponder is whether your current infrastructure relies heavily on GCP or other cloud providers. BigQuery might have the upper hand if your organization is deeply invested in the GCP ecosystem due to its seamless integration with other Google Cloud services. However, if your organization uses a diverse set of cloud services or is not tied to a specific cloud provider, Snowflake's multi-cloud support and flexibility might be more suitable.
