About Amazon Redshift
AWS's data warehouse, sitting next to the rest of your AWS data.
Amazon Redshift launched in February 2013, built on top of MPP technology Amazon licensed from ParAccel and modelled on an early PostgreSQL fork. It runs in two shapes: Provisioned, where you size RA3 nodes (compute) against managed storage on S3, and Serverless, where you pay per Redshift Processing Unit (RPU) by the second and AWS scales the compute for you. Both share the same SQL surface and the same storage layer.
What makes Redshift the natural pick for AWS-first teams is what sits around it. Spectrum reads Parquet, ORC and JSON straight out of S3 without loading first. Zero-ETL integrations stream Aurora, RDS and DynamoDB changes into the warehouse without a separate pipeline. Federated Query joins Postgres or MySQL tables live. Redshift ML calls SageMaker from SQL. If your application data, your event logs and your data science already live in AWS, the warehouse stops being a separate destination and starts being the read model on top of what is already there.
