Amazon RDS vs Amazon Redshift vs Amazon DynamoDB : Amazon RDS: Amazon Redshift: Amazon DynamoDB: Amazon SimpleDB: Database engine: Amazon Aurora, MySQL, MariaDB, Oracle Database, SQL Server, PostgreSQL: Redshift (adapted PostgreSQL) NoSQL: NoSQL (with limited capacity) Computing resources: Here, Scan reads all table items that offer flexibility, but it can slow down the query processing speed especially for the large tables. By this, you can easily select the database engine of your choice and continue your development process. Multi-AZ deployments for the MySQL, MariaDB, Oracle, and PostgreSQL engines utilize synchronous physical replication. Here the data availability is also present just like RDS but is automatically replicated among three Availability zones within selected region. SimpleDB is used for lightweight and easily managed databases. In this feature, the replica of the full database is stored along with its settings at a completely different and distant location that has a different availability zone as well. DynamoDB is REALLY powerful at scale and reduces a lot of the care in feeding, but it's really different than standard SQL and requires quite a bit of a learning curve. A good mental model for choosing between RDS and DynamoDB could be this: if you’ll be relying a lot on relational data structures, RDS could be a better fit.
