Snowflake Architecture Diagram

The Snowflake Architecture refers to the unique design of the Snowflake Data Platform, a cloud-based data warehouse solution built for handling large-scale data storage, processing, and analysis. Unlike traditional data warehouses, which often have rigid and complex architectures, Snowflake's architecture is designed to be simple, scalable, and highly flexible, making it ideal for modern data-driven businesses.

The platform is built on top of cloud infrastructure (available on AWS, Microsoft Azure, and Google Cloud), providing users with the ability to separate storage, compute, and services. This separation enables users to scale each component independently based on their needs, which makes Snowflake an ideal choice for businesses that require both elasticity and performance at a cost-effective price.

Snowflake's architecture is built around three core layers:

1. Storage Layer:

• All data is stored here.

• Snowflake uses a centralized storage model to handle structured and semi-structured data (e.g., JSON, Avro, Parquet) in a single location.

2. Compute Layer:

• This layer consists of virtual warehouses that handle computational workloads.

• These warehouses scale up or down based on demand, ensuring optimal performance.

3. Cloud Services Layer:

• The cloud services layer manages metadata, query optimization, security, and infrastructure.

• It enables seamless data processing and supports multi-user collaboration.

• Multi-Cluster Shared Data Architecture: Allows users to scale compute resources dynamically so that different workloads (e.g., data loading, querying, and analytics) don't interfere with each other.

• Support for Structured and Semi-Structured Data: Snowflake's versatility accommodates diverse datasets.

• High Availability & Elastic Scalability: Snowflake's design ensures cost-efficiency and seamless integration with analytics tools.

Snowflake's architecture separates its components to allow independent scaling, cost efficiency, and high performance. When a query or data transformation is initiated, Snowflake follows these steps:

1. Data Retrieval: Pulls data from the storage layer (optimized for structured and semi-structured data).

2. Data Processing: Virtual warehouses in the compute layer handle the data query or transformation.

3. Orchestration: The cloud services layer manages the process, ensuring efficient query execution without data conflicts or resource limitations.

• Scalability: Independent scaling of compute and storage resources.

• Flexibility: Supports structured, semi-structured (JSON, Avro), and unstructured data.

• Cost Efficiency: Pay-per-use pricing ensures businesses only pay for what they use.

• Performance Optimization: Advanced query optimization and multi-cluster architecture ensure fast performance.

• Zero Maintenance: Fully managed platform eliminates the need for infrastructure maintenance.

• Security: End-to-end encryption, role-based access control, and compliance with industry standards ensure data safety.

• Data Sharing: Real-time, secure data sharing without replication.

Snowflake employs several strategies to optimize performance:

• Automatic Query Optimization: Ensures efficient execution plans for queries.

• Result Caching: Reduces query times by caching results.

• Elastic Scaling: Dynamically adjusts compute power to meet workload demands.

• Partitioning and Clustering: Automatically organizes data for efficient retrieval.

• Materialized Views: Speeds up query execution by precomputing results.
