Hi, and welcome to this course on Amazon Aurora! In this course we will be covering all of the essentials that you need to know for Amazon Aurora with some deeper dives into Aurora's features, management, security, storage, and reliability, data management, performance, and also troubleshooting topics.

Amazon Aurora is a proprietary technology from AWS and it is not open sourced, but Aurora is compatible with both MySQL and PostgreSQL databases. And the Amazon Aurora db will have compatible drivers so connections from either engine has been made simple and secure. AWS has made Aurora cloud optimized and Amazon Aurora MySQL has 5x the performance improvement over MySQL on RDS and over 3x the performance over Postgres on RDS plus tons of other performance improvements and features that we will cover throughout this course. One of the key differences we will see is that Aurora's is unique to other databases and its storage automatically grows in increments of 10 gigabytes up to 64 terabytes.

So we start off at 10 gigabytes and as we had more data our Aurora storage automatically grows with our data, so you no longer have to worry about managing your disk. Another cool feature of Aurora is that you can have up to 15 read replicas with Aurora compared to 5 read replicas with MySQL and the replication process to the Aurora read replicas is faster. Failover with Amazon Aurora is instantaneous and Aurora is also highly available. Aws estimates that the cost / pricing for Amazon Aurora is around 20% more than RDS, Aurora is more efficient.



As I said we will be covering all of the essentials of Aurora in this course plus some deeper dives too! Let's get started!!!
