Snowflake Cloud Provider Integration

Snowflake provides deep integration with all major cloud providers, enabling seamless connectivity, security, and performance optimization for cloud-native workloads.

What is Cloud Integration?

• Connects natively to AWS, Azure, and GCP
• Provides PrivateLink for secure, private connectivity
• Enables cross-cloud data sharing without data movement

Architecture Overview

The Snowflake multi-cloud architecture connects to three major cloud providers:

Snowflake Data Cloud provides multi-region capabilities with consistent APIs across all providers.

Integration Features

• Networking — PrivateLink, VPC peering
• Security — IAM, KMS, encryption
• Storage — S3, Blob, GCS
• Compute — Lambda, Functions

AWS Integration

S3 External Stage

-- Create storage integration
CREATE OR REPLACE STORAGE INTEGRATION s3_integration
  TYPE = EXTERNAL_STAGE
  ENABLED = TRUE
  STORAGE_PROVIDER = S3
  STORAGE_AWS_ROLE_ARN = 'arn:aws:iam::123456789:role/snowflake-role'
  STORAGE_ALLOWED_LOCATIONS = ('s3://my-bucket/data/');

-- Create external stage
CREATE OR REPLACE STAGE s3_stage
  URL = 's3://my-bucket/data/'
  STORAGE_INTEGRATION = s3_integration
  FILE_FORMAT = (TYPE = 'PARQUET');

AWS PrivateLink

-- Configure PrivateLink
CREATE OR REPLACE ACCOUNT LEVEL PARAMETERS
SET PRIVATE_ENDPOINT = 'vpce-1234567890abcdef0.snowflake.us-east-1.vpce.amazonaws.com';

-- Verify connection
SELECT SYSTEM$TYPE_OF_CONNECTION();

Azure Integration

Blob Storage Stage

CREATE OR REPLACE STORAGE INTEGRATION azure_integration
  TYPE = EXTERNAL_STAGE
  ENABLED = TRUE
  STORAGE_PROVIDER = AZURE
  AZURE_TENANT_ID = 'your-tenant-id'
  AZURE_STORAGE_ALLOWED_LOCATIONS = ('azure://myaccount.blob.core.windows.net/mycontainer/');

CREATE OR REPLACE STAGE azure_stage
  URL = 'azure://myaccount.blob.core.windows.net/mycontainer/data/'
  STORAGE_INTEGRATION = azure_integration;

Azure Private Link

CREATE OR REPLACE ACCOUNT LEVEL PARAMETERS
SET PRIVATE_ENDPOINT = 'privatelink.snf-abc123.database.windows.net';

GCP Integration

GCS Stage

CREATE OR REPLACE STORAGE INTEGRATION gcs_integration
  TYPE = EXTERNAL_STAGE
  ENABLED = TRUE
  STORAGE_PROVIDER = GCS
  GCS_STORAGE_ALLOWED_LOCATIONS = ('gcs://my-bucket/data/');

CREATE OR REPLACE STAGE gcs_stage
  URL = 'gcs://my-bucket/data/'
  STORAGE_INTEGRATION = gcs_integration;

Cross-Cloud Data Sharing

-- Share data across clouds
CREATE SHARE cross_cloud_share;
GRANT USAGE ON DATABASE my_db TO SHARE cross_cloud_share;
GRANT USAGE ON SCHEMA my_schema TO SHARE cross_cloud_share;
GRANT SELECT ON TABLE my_table TO SHARE cross_cloud_share;

-- Consumer account (different cloud)
CREATE DATABASE shared_data FROM SHARE provider_account.cross_cloud_share;
SELECT * FROM shared_data.my_schema.my_table;

Security Integration

Key Management

-- AWS KMS encryption
CREATE OR REPLACE STORAGE INTEGRATION encrypted_s3
  TYPE = EXTERNAL_STAGE
  STORAGE_PROVIDER = S3
  STORAGE_AWS_ROLE_ARN = 'arn:aws:iam::role/snowflake-role'
  STORAGE_AWS_KMS_KEY_ARN = 'arn:aws:kms:us-east-1:123456789:key/12345678-1234-1234-1234-123456789012';

-- Azure Key Vault
CREATE OR REPLACE STORAGE INTEGRATION encrypted_azure
  TYPE = EXTERNAL_STAGE
  STORAGE_PROVIDER = AZURE
  AZURE_TENANT_ID = 'tenant-id'
  AZURE_ENCRYPTION_TYPE = 'AZURE_KEY_VAULT'
  AZURE_KEY_URL = 'https://mykeyvault.vault.azure.net/keys/mykey';

Network Security

-- IP restrictions
ALTER ACCOUNT SET NETWORK_POLICY = 'restricted_policy';

-- Network policy
CREATE OR REPLACE NETWORK POLICY restricted_policy
  ALLOWED_IP_LIST = ('203.0.113.0/24', '198.51.100.0/24')
  BLOCKED_IP_LIST = ('192.0.2.0/24');
