RDS
RDS (Amazon Relational Database Service) is Amazon's way of providing ready-to-use databases in the cloud. Think of it like renting a fully-managed database instead of building and maintaining one yourself. It's similar to having a landlord take care of all building maintenance while you just live in the apartment. Companies use RDS because it saves them time and effort - Amazon handles all the complicated parts like backups, updates, and security. This is part of Amazon's cloud services (AWS), and it's popular among companies that want their databases to be reliable without having to hire a large team of database experts.
