ℹ️ Information: Before deploying Amazon RDS, we need to set up the necessary network infrastructure and security components to ensure proper connectivity and security for our database environment.
💡 Pro Tip: When creating subnets for your RDS deployment, distribute them across at least two Availability Zones to enable Multi-AZ deployments for high availability.
🔒 Security Note: Security Groups act as virtual firewalls that control inbound and outbound traffic. For RDS, configure your security group to only allow traffic on the database port from authorized sources.
⚠️ Warning: DB Subnet Groups must include subnets in at least two different Availability Zones to support Multi-AZ deployments. Without this configuration, you won’t be able to enable the Multi-AZ feature for your RDS instances.
