Understanding Amazon RDS (Relational Database Service) – Complete Beginner Guide
Introduction
As part of my learning journey at Millennium Software Solutions, I learned about Amazon RDS (Relational Database Service), one of the most important database services in AWS.
Managing databases manually can be complex and time-consuming. Amazon RDS simplifies this process by allowing users to create, manage, and scale databases without worrying about hardware, operating systems, backups, or maintenance.
In this article, I will explain Amazon RDS in a simple and beginner-friendly way.
What is Amazon RDS?
Amazon RDS stands for:
Relational Database Service
It is a managed database service provided by AWS.
RDS helps users create and manage databases in the cloud without handling server administration tasks.
In simple words:
Amazon RDS allows you to run databases in AWS without installing and maintaining database servers manually.
What is a Database?
A database is a collection of organized data.
Examples:
Student Records
Employee Information
Banking Data
Customer Details
E-commerce Product Information
A database helps store, retrieve, update, and manage data efficiently.
Why Do We Need Amazon RDS?
