Aurora is compatible with both MySQL and PostgreSQL, enabling seamless migration and integration with existing applications that use these widely adopted database systemsOne of Aurora's standout features is its high scalability. It can automatically scale storage from 10 GB up to 128 TB per database instance, ensuring that applications can handle growing data demands without manual intervention. Additionally, Aurora supports up to 15 low-latency read replicas, which enhance read throughput and enable applications to handle high-volume queries efficientlyAvailability and durability are central to Aurora’s design. It automatically replicates data across multiple Availability Zones (AZs) within a region, providing robust fault tolerance. In the event of an AZ failure, Aurora can automatically failover to a replica, minimizing downtime and ensuring continuous application availability. Its storage engine is engineered for durability, replicating data six ways across three AZs and continuously backing up data to Amazon S3Performance is another key advantage of Aurora. It delivers up to five times the throughput of standard MySQL and up to three times that of PostgreSQL without requiring application changes. This performance enhancement is achieved through a combination of architectural optimizations and efficient use of AWS infrastructureAurora also offers security features, including encryption at rest and in transit, integration with AWS Identity and Access Management (IAM) for fine-grained access control, and compliance with various industry standards. Furthermore, Aurora Serverless provides an on-demand, auto-scaling configuration that automatically adjusts capacity based on application requirements, optimizing costs for variable workloadsFor the AWS Certified Cloud Practitioner, understanding Amazon Aurora is essential as it exemplifies key AWS database services' principles, such as managed services, scalability, high availability, and integration within the AWS ecosystem. Mastery of Aurora supports effective cloud architecture design and data management strategies in AWS environments.
