What this card says
What it is
RDS (Relational Database Service) is a database that AWS runs for you: MySQL, PostgreSQL and more.
You still use normal SQL.
Why companies use it
AWS handles the server, patches and automatic backups.
Why it matters for security
“Managed” does not mean your data is safe by default.
AWS secures the platform. You must keep it private, use strong passwords and limit who can connect.
| Task | MySQL on your own EC2 | Amazon RDS MySQL |
|---|---|---|
| Install and OS patching | You | AWS |
| MySQL minor upgrades | You | AWS (maintenance window you choose) |
| Backups | You write mysqldump + cron | Automated daily backups + transaction logs |
| High availability | You build replication | Tick Multi-AZ |
| SSH to the database server | Yes | No – only the MySQL port |
