Relational database technologies on Azure and AWS

RDS and Azure relational database services

Azure provides several different relational database services that are the equivalent of AWS' Relational Database Service (RDS). These include:

Other database engines such as SQL Server, Oracle, and MySQL can be deployed using Azure VM Instances.

Costs for AWS RDS are determined by the amount of hardware resources that your instance uses, like CPU, RAM, storage, and network bandwidth. In the Azure database services, cost depends on your database size, concurrent connections, and throughput levels.
