AWS Database Services

AWS provide a wide range of database solutions to its users.

Depending upon the nature of the data, security and the cost constraints of the customers various database types serve all users accordingly.

These Databases allow users to build use-case-specific data models, including relational, graph, wide-column, etc. AWS fully manages these databases, freeing users from some maintenance tasks such as server provisioning, patching, and backup, which are time-consuming.


  • Fully Managed: AWS Database services are fully managed services that release many of the setup, management, and monitoring responsibilities from customers.
  • Scalable: AWS provides a set of Databases that are highly scalable. This is true for both the relational and non-relational databases.
  • Highly available: considering its global infrastructure setup and fault tolerance mechanism, AWS provides highly available and reliable services across the globe.
  • Security: Provides secure services due to the implementation of multi-level security systems like network isolation and end-to-end encryption.

Amazon RDSseveral database instances types – optimized for memory, performance or I/O
provides you with six familiar database engines to choose
Amazon Aurora
Oracle Database
SQL Server
AWS Database Migration Service
to easily migrate or replicate your existing databases to Amazon RDS
Amazon RDS on VMwaredeploy managed databases in on-premises
allows you to utilize the same simple interface for managing databases in on-premises VMware environments as you would use in AWS
enabling low-cost hybrid deployments for disaster recovery, read replica bursting, and optional long-term backup retention in Amazon Simple Storage Service (Amazon S3)
