AWS Database Certification

• Horizontal Scaling: Understand how to add more nodes for scaling databases like DynamoDB or Amazon Aurora.
• Vertical Scaling: Know when to scale up and down for resource optimization.
• High Availability: Master techniques like Multi-AZ deployment and read replicas to achieve database reliability and high uptime.
In the AWS Database Certification exam, these skills are particularly useful as they relate to designing and maintaining systems that are both cost-efficient and scalable in large-scale production environments.
