Business information stored in a cloud based data warehouse is accessible and available for analytical processing in a cloud. Data is usually gathered from a variety of sources, then restructured and brought into the warehouse via data pipes. Users then can access the stored data via SQL and link it to business intelligence or analytics. Cloud infrastructure enables companies to scale up or down with computing power if they need it for workloads. This can enhance flexibility and accessibility and help to decrease physical server usage. Other security measures such as access controls, encryption, monitoring, and backups can help safeguard contents stored on the computer.
