Managed Databases

Stop patching your own SQL Server VMs. RDS automates backups, software patching, and high availability.

1. Multi-AZ Deployments

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.

2. Read Replicas

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).

3. Architect Insight

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."
