What Is AWS Aurora?

AWS Aurora is an AWS database service compatible with MySQL and PostgreSQL and built for the cloud. Its cloud hosted architecture is designed to take full advantage of the elastic scalability in modern cloud environments. Aurora's storage layer is distributed, fault-tolerant, and self-healing, thereby providing you with enterprise-level durability and availability.

The performance of AWS Aurora is up to five times better than typical MySQL databases and three times better than standard PostgreSQL databases. This makes it one of the fastest growing services of AWS. Now that we have a basic understanding of what AWS Aurora is, let's delve into its key features.

Key Features of AWS Aurora

High Performance and Scalability

One of the key features of AWS Aurora is its high performance and scalability. This allows it to handle large amounts of data and traffic without any issues. With its distributed, fault-tolerant, and self-healing storage system, it can scale up to 64 terabytes per database instance.

Moreover, Aurora automatically scales your database’s compute and memory resources in real time, without any downtime. This ensures that your database can handle sudden increases in workloads and still maintain high performance. Aurora's multi-master feature further enhances its performance by allowing reads and writes to be served from multiple instances in a database cluster.

Scalability also comes with Aurora's serverless offering. The serverless option automatically starts, scales, and shuts down an Aurora database, making it ideal for applications with unpredictable or cyclical workloads.

Durability and High Availability

When it comes to data, durability and availability are paramount. AWS Aurora excels in these aspects by providing multiple features that ensure your data is safe, secure, and available when you need it.

Aurora replicates each chunk of your database volume six times across three Availability Zones (AZs). This replication not only provides high durability but also helps in recovery from physical storage failures. Aurora can handle the loss of up to two copies of data without affecting database write availability and up to three copies without affecting read availability.

Aurora's high availability is also enhanced by its failover support for Aurora replicas. In case of a primary instance failure, Aurora automatically fails over to a replica in the same or different AZ without any data loss or downtime.

Compatibility with MySQL and PostgreSQL

AWS Aurora is fully compatible with popular open-source databases MySQL and PostgreSQL. This means that if you're currently using a MySQL or PostgreSQL database, you can migrate to Aurora without any modifications to your existing applications.

This compatibility makes Aurora an attractive choice for businesses looking to leverage the benefits of AWS cloud services while keeping their existing database systems. Aurora's compatibility with these databases extends to all the layers, including the user interface, language support, and most importantly, the data itself.

Moreover, Aurora supports both the community and commercial editions of MySQL, and all the features of PostgreSQL, thereby providing a seamless transition path for users of these databases.

Automated Backups and Snapshots

One of the most critical features of any database system is the ability to recover lost data. With AWS Aurora, you don't have to worry about data loss as it provides automated backups and snapshots.

Aurora automatically backs up your data to Amazon S3, which has a durability of 99.999999999%. These backups are continuous and capture your database's data and transaction logs. This means you can recover your database to any point in time during your backup retention period.

Apart from automated backups, Aurora also allows you to take database snapshots. These snapshots are user-initiated backups of your entire DB instance. You can use these snapshots to restore your database instance to the exact state it was in when the snapshot was taken.

Monitoring and Performance Insights

Monitoring is an essential aspect of managing and maintaining a healthy database system. AWS Aurora provides several features that allow you to monitor your database's performance and troubleshoot any issues.

Aurora integrates with CloudWatch, an AWS service that provides real-time monitoring of AWS resources and applications. With CloudWatch, you can collect and track metrics, collect and monitor log files, and set alarms.

Aurora also provides Performance Insights, an easy-to-use tool that helps you quickly assess the load on your database and determine when and where to take action. Performance Insights offers a simple visual explanation of database performance and can handle thousands of concurrent connections to the database.
