AWS RDS Database Table of Contents Overview When to Use Quick Start Reference Guides Best Practices Overview Amazon RDS simplifies relational database deployment and operations. Support multiple database engines with automated backups, replication, encryption, and high availability through Multi-AZ deployments. When to Use PostgreSQL and MySQL applications Transactional databases and OLTP Oracle and Microsoft SQL Server workloads Read-heavy applications with replicas Development and staging environments Data requiring ACID compliance Applications needing automatic backups Disaster recovery scenarios Quick Start Minimal working example: # Create DB subnet group aws rds create-db-subnet-group \ --db-subnet-group-name app-db-subnet \ --db-subnet-group-description "App database subnet" \ --subnet-ids subnet-12345 subnet-67890 # Create security group for RDS aws ec2 create-security-group \ --group-name rds-sg \ --description "RDS security group" \ --vpc-id vpc-12345 # Allow inbound PostgreSQL aws ec2 authorize-security-group-ingress \ --group-id sg-rds123 \ --protocol tcp \ --port 5432 \ --source-security-group-id sg-app123 # Create RDS instance aws rds create-db-instance \ --db-instance-identifier myapp-db \ --db-instance-class db.t3.micro \ --engine postgres \ --engine-version 15.2 \ // ...
