Traditional data warehouse models have worked well for a long time. They were the backbone of many business intelligence strategies—with clearly defined data pipelines, standard reporting, and historical data storage.
But the reality of our business has changed:
- Data sources are exploding: IoT, CRM, ERP, social media, weblogs - data is coming from all directions.
Speed matters: Decisions must be made in real time, not based on last week's report.
Use cases are dynamic: Today we need a sales forecast, tomorrow an AI-based customer classification.
This dynamic breaks down the rigid structures of traditional data warehouses.
Reality vs. Expectation: The Challenge of Migration
A common misconception is that modernizing or migrating an existing data warehouse to the cloud is a quick process. However, as the Eckerson Group report makes clear, it is “not quick or easy.” The authors describe the transition as a “challenging multi-step process” that spans many phases: from schema and data migration to ETL adjustments to the integration of metadata, security concepts, and applications.
Especially in mature system landscapes, this process can take months – often involving budget and resource commitments, uncertainty, and change processes. In short: a project that demands a lot before it delivers any benefits.
Out-of-the-box – what does that mean?
An “out-of-the-box data warehouse” does not refer to a product in a box that we just need to plug in. It represents a new way of thinking:
- Modularity instead of monolith: Small, reusable data modules instead of huge tables.
- Cloud-native architecture: Flexibility, scalability, and cost control - without your own data center.
- Self-service for business users: Data must be available where decisions are made - even without an IT ticket.
- Automation and AI: ETL is a thing of the past. Today we talk about ELT, automated data mapping, and semantic data modeling with the support of machine learning.
And yes, it can be done even faster. Companies such as Konica Minolta demonstrate that a modern data warehouse can be up and running within a day, including connections to relevant data sources. This makes “out-of-the-box” not just a promise, but a reality.
