How does this approach of data warehouse grow so rapidly in popularity? What are its use cases? How can it be a valuable addition to your business’s operations? Let’s find out.

What is a cloud data warehouse?

A cloud data warehouse is an enterprise-level data platform hosted in the cloud, designed for analyzing and generating reports from structured and semi-structured data gathered from various sources. 

It provides a centralized repository for organizing and accessing data from various sources to support business intelligence, analytics, and decision-making. 

Cloud data warehouses typically offer the following key features: 

• Massively parallel processing (MPP): These warehouses support big data applications by using MPP architecture, where multiple servers operate in the form of clusters. This setup enables fast query performance by distributing processing tasks and managing numerous input/output (I/O) operations simultaneously. 

• Columnar data storage: MPP warehouses generally use columnar databases, which store data by columns rather than rows. This format is more cost-effective and flexible for analytics, significantly accelerating aggregate queries commonly used in reports and insights generation. 

Traditional data warehouse vs. Cloud data warehouse: How to differentiate them  

Let’s compare them based on SIX factors: Location, cost, flexibility and scalability, security, maintenance, and integration.  

Location 

A key difference between the two approaches is their deployment model. On-premise data warehouses are hosted and managed within a company’s own data centers, requiring significant upfront investment in hardware and infrastructure. In contrast, cloud data warehouses are hosted on third-party cloud platforms, enabling companies to access and manage their data remotely. 

• On-premise: Requires physical servers and dedicated data centers. The organization is responsible for purchasing, installing, and maintaining the hardware. 

• Cloud: Operates on a third-party provider’s infrastructure. Companies can deploy, access, and manage their data through an internet connection, reducing the need for physical infrastructure. 

Cost 

The responsibility for managing infrastructure differs significantly between cloud and on-premise data warehouses.
