Stop patching your own SQL Server VMs. RDS automates backups, software patching, and high availability.
With one click, RDS creates a synchronous 'Standby' replica in a different Availability Zone. If the primary DB fails, RDS automatically fails over to the standby. Your .NET connection string stays the same. This is 'Mission Critical' architecture.
Create up to 5 read-only copies of your DB. **Architect Tip:** Point your reporting tools and dashboard queries to the **Read Replica** to keep your primary DB fast for write operations (Transactions).
Q: "Should I use RDS or Aurora?"
Architect Answer: "Use **Amazon Aurora** (PostgreSQL/MySQL compatible). It's built specifically for the cloud, 5x faster than standard MySQL, and can auto-scale storage up to 128TB. It also features 'Serverless' mode, which can shut down the DB when not in use to save money during development."
