Amazon RDS Key Features
1. High Availability
Amazon RDS provides high availability through the Multi-AZ (Availability Zone) feature. This ensures that your database remains operational even in the event of an infrastructure failure.
2. Scalability
With Amazon RDS, you can easily scale your database instance up or down based on your application's needs. This can be done either manually or through the use of RDS Auto Scaling.
aws rds modify-db-instance --db-instance-identifier your-db-instance-id --allocated-storage 100
3. Automated Backups
RDS provides automated backups of your database, allowing point-in-time recovery. Backups are taken daily and retained for a user-defined period.
4. Security
Amazon RDS offers several layers of security including encryption at rest and in transit, security groups, and VPC isolation.
aws rds create-db-instance --db-instance-identifier your-db-id --master-username your-username --master-user-password your-password --allocated-storage 20 --db-instance-class db.t2.micro --engine mysql --vpc-security-group-ids your-security-group-id
5. Monitoring and Performance
Amazon RDS integrates with Amazon CloudWatch for monitoring database performance metrics and logs. It allows you to set alarms for certain metrics, aiding in performance optimization.
6. Multi-Database Support
RDS supports several database engines including MySQL, PostgreSQL, MariaDB, Oracle, and SQL Server, allowing users to choose the right database for their application.
