Prerequisite Steps

Overview of Prerequisites

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.

Required Network Components

  1. Create a Virtual Private Cloud (VPC)
  2. Create Subnets across multiple Availability Zones
  3. Create Security Group for Amazon EC2 instances
  4. Create Security Group for Amazon RDS DB instances
  5. Create DB Subnet Group for Amazon RDS

💡 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.
