Building a Cloud Data Warehouse

Project Overview
A software development company partnered on an ambitious project to build a state-of-the-art Cloud Data Warehouse designed to support comprehensive reporting and ad hoc analysis. The primary objective was to create a scalable, flexible data platform capable of handling diverse data processing needs while enabling future growth in advanced analytics.
Key Objectives
- Develop a robust Cloud Data Warehouse for reporting and analysis
- Support batch and near real-time data processing
- Facilitate advanced analytics capabilities
- Ensure scalability through multi-tenant architecture

Key Roles and Responsibilities:
The success of the project was driven by a dedicated team with distinct roles:
- Data Platform Design: Architecting a scalable and flexible data platform
- Data Architecture: Implementing Lakehouse principles for modern data management
- Pattern Development: Designing best practices for data architecture
- ETL Design: Crafting robust ETL techniques for efficient data processing

The platform was engineered using the Medallion Architecture, enhancing data quality and governance across bronze, silver, and gold layers. The hybrid cloud approach leverages AWS, GCP, and Snowflake, ensuring flexibility, resilience, and scalability.
Key architectural highlights include:
- Multi Cloud Deployment: Combining AWS and GCP for optimal performance and reliability
- Multi-Tenancy Design: Supporting diverse client requirements with isolated data environments
- Lakehouse Implementation: Bridging the gap between data lakes and data warehouses
- Metadata-Driven Frameworks: Automating data ingestion, ETL, and orchestration to prevent vendor lock-in
Core Functionalities:
The platform’s advanced capabilities are built through metadata-driven frameworks, delivering:
- Data Ingestion: Automated and scalable ingestion pipelines
- Data Transformation: Seamless loading of data into silver and gold zones
- Orchestration: Efficient management of workflows and data pipelines
- Data Reconciliation: Ensuring data consistency and accuracy
- Schema Evolution: Dynamic handling of schema changes with automated downstream updates
- Data Quality: Continuous monitoring and improvement of data integrity
Project Achievements:
- Successful implementation of a multi-tenant multi cloud data platform
- Development of automated pipelines with dynamic schema evolution handling
- Enhanced data quality and governance through metadata-driven processes
- Scalable architecture ready to support future advanced analytics initiatives
- Increased operational efficiency through automation of code, scripts, and data workflows

Tools and Technologies
The platform leverages cutting-edge technologies to meet company‘s business needs:
- AWS Services: Lambda Functions, AWS Glue, AWS S3
- GCP Services: Cloud Storage, Cloud Functions
- Data Warehouse: Snowflake
Impact and Success
The company’s Cloud Data Warehouse has transformed the company’s data landscape, providing a reliable, scalable, and flexible platform for data-driven decision-making. The multi-tenant, hybrid architecture ensures that diverse client requirements are met, while the metadata-driven framework enables rapid adaptation to evolving business needs. This project has laid the foundation for future growth in advanced analytics, positioning the company at the forefront of data innovation.
