Summary

Let’s quickly summarize what we have learned in the Database module:

Relational Database Service (RDS)

Amazon RDS simplifies relational database management with automated scaling, backup, and monitoring.

  • It supports popular database engines like PostgreSQL, MySQL, and Aurora.

  • Developers choose instance classes, types, and EBS storage options based on workload needs.

  • Deployment options include Single-AZ, Multi-AZ Instance, and Multi-AZ DB Cluster for varying availability and scalability.

  • Multi-AZ DB Clusters enable automatic failover and read scalability with semi-synchronous replication.

Amazon Aurora

Amazon Aurora is a cloud-optimized relational database service compatible with MySQL and PostgreSQL.

  • Aurora clusters feature fault-tolerant, multi-AZ distributed storage with independent compute scaling.

  • High availability is built-in, with automatic failover among Aurora Replicas across AZs.

  • Aurora global databases enable low-latency reads and disaster recovery across multiple AWS regions.

  • Automated backups and manual snapshots offer flexible data recovery and cloning options.

  • Aurora Serverless v2 provides auto-scaling database capacity for variable and unpredictable workloads. ...
