AWS > Database > Amazon Redshift:
Amazon Redshift is a fully managed, petabyte-scale data warehouse service in the cloud.
Redshift can be configured as follows:
1. Single Node (160Gb)
2. Multi-Node:
2a. Leader Node: Manages Client connections and receives queries.
2b. Compute Node: Store data and perform queries and computations. (Up to 128 compute Node)
Backups:
1. Enabled by default with a 1 day retention period.
2. Maximum retention period is 35 days.
3. Redshift always attempts to maintain at least three copies of your data(the original and replica on the compute node and backup in the S3)
4. Redshift can also asynchronously replicate your snapshots to S3 in another region for disaster recovery.
Priced:
1. Total compute node per node per hour. You will not be charged for leader node hours.
2. Backup
3. Data transfer (only within a VPC, not outside it)
