Snowflake CI/CD Part 2 – Build Secure DEV / UAT / PROD Infrastructure

Описание: This is Part 2 of the Snowflake CI/CD Series.

In this episode, we build the environment architecture required for production-grade DevOps in Snowflake.

CI/CD without environment isolation is not CI/CD — it’s just scripting.

🔎 What We Build

In this session we create:

Dedicated virtual warehouses (DEV, UAT, PROD)

Separate databases per environment

Isolated schemas

Environment-specific deploy roles

Passwordless CI/CD service users

RSA key-based authentication

Least-privilege role design

This mirrors real enterprise production environments used in regulated industries such as NHS, Finance, and Government.

🏗 Architecture Pattern

We implement:

One Snowflake account

Three logical environments

Environment-specific warehouses

Environment-specific roles

Dedicated CI/CD users per stage

This ensures:

Safe promotion (DEV → UAT → PROD)

Controlled privilege boundaries

Reproducible deployments

Secure automation via GitHub Actions

🧱 SQL Covered in This Video

We create:

WH_DEV, WH_UAT, WH_PROD

NHS_DEV, NHS_UAT, NHS_PROD

ROLE_DEV_DEPLOY, ROLE_UAT_DEPLOY, ROLE_PROD_DEPLOY

CICD_DEV, CICD_UAT, CICD_PROD

RSA key-based authentication setup

📌 Why This Matters

Most Snowflake demos:

Use a single warehouse

Use a single database

Ignore separation of duties

Ignore security posture

Real production systems require:

Role isolation

Warehouse cost boundaries

Privilege scoping

Secure service accounts

This is how you design Snowflake for production.
