What Is a Data Warehouse — A Quick Recap
A data warehouse is a centralized repository designed for analytics and reporting, storing historical data from multiple operational systems in a format optimized for queries and insight generation.
Unlike transactional systems, data warehouses are built for:
✔ Fast analytical queries
✔ Complex joins across domains
✔ Historical trend analysis
✔ Data integration from diverse sources
How to Use This Guide
Each section includes:
- Tool Overview

1️⃣ Amazon Redshift
Overview:
AWS’s flagship cloud data warehouse — fully managed, massively parallel processing (MPP), and deeply integrated with the AWS ecosystem.
Architecture Diagram Prompt
A high-level diagram showing Redshift clusters (compute + storage), data ingestion via AWS Glue and Kinesis, S3 as long-term storage, and BI tools like QuickSight querying through JDBC/ODBC. Include auto-scaling and concurrency scaling layers.
Cost Model
Pricing components:
Compute nodes: charged per hour
Storage: per GB/month
Data transfer: depending on region
Concurrency scaling: extra charges
Reserved instances: up to 75% off
Redshift Spectrum allows querying data directly on S3 (pay per TB scanned).
When NOT to Use
❌ You need real-time analytics — Redshift is strong for batch loads.
❌ You have unpredictable workload spikes without reserved planning — concurrency scaling can get expensive.
2️⃣ Google BigQuery
Overview:
A serverless, fully managed data warehouse with truly elastic scaling. BigQuery separates compute and storage, and charges mostly on data processed.
Architecture Diagram Prompt
Show BigQuery’s serverless model with separated storage and compute, data ingested via Dataflow/Cloud Pub/Sub, and dashboards like Looker accessing via BigQuery API.
Cost Model
Two main models:
✔ On-demand pricing: pay per TB scanned
✔ Flat-rate: predictable monthly compute
Storage: priced per GB monthly.
Streaming inserts: additional cost.
When NOT to Use
❌ You want predictable low-cost small workloads with minimal query volume — on-demand scanning charges may be high for small teams.
❌ You’re locked into non-Google ecosystems (complex connectors needed).
