Amazon Relational Database Service

I'm reading about RDS. I am understanding DB instances are simply EC2s where Amazon installs DB engines. Is that correct? AWS says that the DB instance is an isolated database environment in AWS cloud. What does it mean? How can it isolate?

Hi,

RDS is a managed service. So, yes, it runs on EC2 instances. But, you don't manage / operate them (patching, availability, redundancy, snapshotting, etc.). So, your effort is very reduced compared to a use case where you would create the EC2 instances yourself.

The second stage in getting rid of the "undifferentiated heavy-weight lifting" is to go serverless with Aurora Serverless: https://aws.amazon.com/rds/aurora/serverless/

Aurora will additionally take care of autoscaling for you. Additionally, the model is more pay-as-you-use: it proves cheaper than RDS where the utilization of your dbms is low. With RDS, you pay per hour even if you don't use the db.

Have a good start with RDS / Aurora

    Thank you for your answer. I have another question about the isolated database environment. What is an isolated database environment? Please answer me.

    Isolated means that you have no access to the operating system and have to use the published API interfaces to manage the engine.
