Amazon’s RDS	Amazon’s DynamoDB	Amazon’s ElastiCache	Amazon’s Redshift
It is a managed Relational database.	It is NoSQL database.	It is an in-memory data store.	It is a data warehouse.
Provides service with easy setup. It is easy to operate and could be scaled in the cloud.	It is fast and flexible that provides a NoSQL database service for the application in a consistent and single millisecond latency at required scale.	It could be deployed, operated and scaled effortlessly operated in an open source compatible in memory data store.	It is simple, fast and cost effective fully managed data warehouse to manage the data using the SQL and existing Business Intelligence tools.
It is used in OLTP (Online Transaction Processing) systems.	It can be used in the system that requires millisecond read latency at required scale.	It can be used in the system that requires sub- millisecond response time.	It is used for the OLAP (On Line Analytical Processing) systems.
It supports read replicas across regions and gets backup at Amazon S3.	It uses streams to replicate the data to a table and to another table and does not require any backup.	Replicas are provided based on the read scaling and gets backup automatically.	Data gets replicated automatically and gets backup in Amazon S3.
It resides inside the Virtual Private cloud	It does not resides inside the Virtual Private Cloud	It performs based on the “memcached” or “Redis” in the cloud.	It resides inside the Virtual Private cloud
