AeroTech's Enterprise Data Warehouse Migration to Cloud
Data Warehousing and Business Intelligence
Medium
💼 Scenario
AeroTech is an aerospace manufacturer with $6 billion in annual revenue that has operated an on-premises data warehouse for 15 years. The warehouse contains 20 TB of historical data spanning manufacturing quality, supply chain, financial, and customer service domains. It currently supports 2,500 business users and 400 scheduled reports.
The on-premises infrastructure is reaching end-of-life and requires a $5 million hardware refresh. The CIO proposes migrating to a cloud-based data warehouse platform instead, projecting a 40% cost reduction over five years. However, the migration faces several challenges: complex ETL pipelines with 800 jobs running on legacy tools, 400 reports that need to be validated post-migration, data residency requirements for defense contract data that must remain in specific geographic regions, and a business requirement for zero downtime during migration.
The analytics team also wants to modernize the architecture to support real-time dashboards (current latency is 24 hours), self-service analytics, and integration with a new data science platform for predictive maintenance models.
