Question
A company is migrating an on-premises relational database server to the AWS cloud and wants to minimize the administrative overhead of database maintenance tasks.
A. Amazon DynamoDB
B. Amazon EC2
C. Amazon Redshift
D. Amazon RDS
Answer
D. Amazon RDS
Explanation
Amazon RDS is a fully managed relational database service that handles routine database tasks such as provisioning, patching, backup, recovery, failure detection, and repair. It supports multiple database engines, including MySQL, PostgreSQL, Oracle, SQL Server, and Amazon Aurora.
When migrating an on-premises relational database to the AWS Cloud, minimizing administrative overhead is a key consideration. Among the provided options, Amazon RDS (Relational Database Service) is the most suitable choice. Here’s why:
Fully Managed Service
Amazon RDS automates routine database management tasks such as:
- Provisioning
- Software patching
- Backup and recovery
- Failure detection and repair
This eliminates the need for manual intervention, allowing organizations to focus on their applications rather than database maintenance.
High Availability and Scalability
Amazon RDS supports Multi-AZ deployments, automated backups, and read replicas for scaling read-heavy workloads. These features ensure reliability and performance without requiring extensive administrative effort.
Familiar Database Engines
RDS supports popular relational database engines like MySQL, PostgreSQL, MariaDB, Oracle, and SQL Server. This compatibility allows seamless migration with minimal changes to existing applications.
Why Not the Other Options?
A. Amazon DynamoDB: While DynamoDB is a fully managed NoSQL database service, it is not designed for relational database use cases. It lacks support for SQL-based queries and relational data models.
B. Amazon EC2: Running a database on EC2 requires manual management of the operating system, database software, backups, scaling, and patching. This approach increases administrative overhead compared to RDS.
C. Amazon Redshift: Redshift is optimized for data warehousing and analytics workloads rather than transactional relational databases. It is not ideal for general-purpose relational database migration.
Key Takeaways for the CLF-C02 Exam
- Amazon RDS is the go-to solution for reducing operational complexity in relational database management.
- It automates critical tasks like backups, patching, and scaling, making it a cost-effective and efficient choice.
- Understanding the use cases of AWS services like RDS, DynamoDB, EC2, and Redshift is essential for passing scenario-based questions in the AWS Certified Cloud Practitioner exam.
By selecting Amazon RDS, companies can streamline their cloud migration process while ensuring high availability and minimal administrative burden.
