Aurora

• Proprietary database by AWS
• Data is replicated to 6 Replicas in 3 AZ
• Auto healing capability
• Multi AZ
• Auto scaling read-replica
• Storage from 10GB to 64TB
• Aurora Global database for DR and Latency Uses
• Need to provision EC2 Instance and EBS Volume
• Using Aurora Serverless does not require instance and volume
• 5x faster than regular RDMS
• Support MAX 15 Read Replicas
• We can create custom endpoint for
• Production Database
• Reporting queries
• Built in reader-endpoint can be used for distribute the traffic between read-replicas
• If DB Primary Instance fails, it create a new DB Instance in the same AZ as the Original Instance and done by Best Effort basis
• Read Replicas can be used to avoid un necessary downtime
• With binlog replication, another aurora cluster can be used as read replica. Aurora cluster can be same or different region
• Aurora auto scaling policy can be used to adjust performance
• Based of number of connections (when the lambda function is using the database)
