Amazon Relational Database Service (RDS) provides several advantages to a database administrator:

1. Managed Service: Amazon RDS is a managed service that takes care of all the maintenance, backups, patch management, failure detection, and recovery.

2. Scalability: Amazon RDS allows easy scaling of your database. You can scale up or down your database's compute and storage resources based on your application's demand.

3. High Availability and Reliability: Amazon RDS provides high availability and reliability by offering Multi-AZ deployments. In case of a failure, Amazon RDS performs automatic failover to the standby so that database operations can resume quickly without manual intervention.

4. Security: Amazon RDS provides several layers of security for your database. These include network isolation using Amazon VPC, encryption at rest using keys you create and control through AWS Key Management Service (KMS), and encryption of data in transit using SSL.

5. Cost-Effective: You pay very low rates and only for the resources you actually consume. There are no upfront costs or long-term commitments.

6. Performance: Amazon RDS supports the most demanding database applications. You can choose between two SSD-backed storage options: one optimized for high-performance OLTP applications, and the other for cost-effective general-purpose use.

Please note that the claim of 99.99999999999% reliability and durability is not accurate. Amazon RDS Service Level Agreement guarantees a Monthly Uptime Percentage of at least 99.95% for Multi-AZ deployments and 99.5% for Single-AZ deployments.
