Cloud data warehouse originates from the concept of the data warehouse but hosted in the cloud. In a data warehouse, integrated data from multiple systems that are presented as reports and analytics often help businesses in making their important decisions. Data warehouses are optimized so that they can store lots of information. The information stored is sourced from a combination of Customer Relationship Management (CRM) systems, accounting systems, product sales systems, etc. Data warehouses offer data in an easily understandable structure (aka schema) to help the end-users analyze and interpret accordingly.
Data warehouses were initially built to store large volumes of data. The data stored was directly related to its computing. Hence, data warehouse services proved to be inefficient, cost-wise, as some data were required to be stored only for the short term. This scenario led to the invent of cloud data warehousing.
Cloud data warehouse is storing data using a network of remote servers hosted on the internet. With a huge increase in data over the past decades, cloud data warehouse serves as a more efficient and cost-effective manner for data storage, performance, simplicity and much more. When compared to traditional data warehousing, features that stand-out for cloud data warehousing are scalability, cost, time to market, and performance.
