Amazon Web Services (AWS) completely changed the way that IT infrastructure is deployed. It is available on demand and is cost-effective. Amazon Redshift is one of the hundreds of AWS services and it is one of the most popular cloud data warehouses. It is fast, secure, and petabyte-scale. Redshift combines the following two important technologies:
- Columnar data store or column-oriented database
- Massively parallel processing (MPP)
You can learn more about MPP and column databases on the Internet. You can find more information about Redshift at AWS's documentation: https://docs.aws.amazon.com/redshift/index.html
