This course is designed to span approximately three hours, encompassing a diverse range of learning materials and activities. Throughout this course, learners will engage with various educational resources, including video content on the Aurora database, reading materials to deepen understanding, graded quizzes to assess comprehension, and thought-provoking discussion prompts to encourage collaborative learning and critical thinking.

Yes, Amazon Aurora supports both MySQL and PostgreSQL database engines, offering customers the flexibility to choose the one that best suits their needs. It provides a managed, highly available, scalable database service compatible with MySQL and PostgreSQL, ensuring seamless migration and operation. This allows users to leverage the performance and reliability benefits of Aurora while maintaining compatibility with their preferred database technology.

Aurora differs from traditional Amazon RDS in several key ways. It is designed for high performance and scalability. It uses a distributed architecture replicating data across multiple availability zones, ensuring high availability and fault tolerance without complex configurations or failover procedures. Traditional RDS databases typically require manual setup for replication and failover.

To enhance the performance of Amazon Aurora, it is advisable to employ read replicas to scale read operations, utilize caching mechanisms, fine-tune queries and indexes, and make the most of Aurora's auto-scaling features. Additionally, it is crucial to consistently monitor database performance and adjust configurations to suit the specific workload demands.

To optimize costs, consider utilizing Aurora Serverless for applications with intermittent or unpredictable workloads. Implementing intelligent auto-scaling configurations can help minimize costs during periods of low activity. Analyzing and optimizing database configurations and instance sizes based on the actual workload can also contribute to cost optimization.

Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:

• The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.

• The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.

You will be eligible for a full refund until two weeks after your payment date, or (for courses that have just launched) until two weeks after the first session of the course begins, whichever is later. You cannot receive a refund once you’ve earned a Course Certificate, even if you complete the course within the two-week refund period. See our full refund policy.
