AWS Unveils Revolutionary Version of Aurora Database, Eliminating I/O Costs

This week, AWS announced that the Amazon Aurora I/O-Optimized version of their Aurora database would be available to the public. The most notable change in this release is eliminating all database I/O fees, which should lower database expenses for clients with heavy workloads and make their cloud database bills more predictable.

Since no fees are associated with I/O activities, users may save money using the new Aurora setup. It’s now easier for customers to transfer more database workloads to AWS since they can more accurately forecast expenses for their most I/O-intensive workloads, the firm said in a statement.

The goal is, of course, to convince customers to move more workloads. However, cost-conscious CIOs may be interested in such a solution as the number of businesses moving to the cloud grows.

The Duckbill Group is a consulting firm that helps clients reduce their AWS expenditures, and its head cloud economist, Corey Quinn, warns that Aurora Enterprise is more expensive than the regular Aurora database. It’s a different approach to setting prices. As Quinn explained to TechCrunch, “they charge more for this model as a baseline rate, so whether or not it’s a good idea to use it will come down to the specifics of a given workload.”

Channy Yun, who works at AWS, said as much in a blog post announcing the update. When your I/O expenditure reaches 25% of your current Aurora database budget, you can now clearly estimate expenses for even your most I/O-intensive workloads while saving up to 40%. You may save even more money using Reserved Instances,” he stated. As you can see, and as Quinn observes, the devil will be in the specifics of your required task.

According to Constellation Research founder and chief analyst Ray Wang, customers with heavy workloads benefit. “In general,” he said, “you pay an I/O fee every time you read non-cached data and then write that data back to your mySQL or Postgres data.” They’ve discovered an internal solution, and now they’re passing the savings on to consumers as we enter the era of AI, so your prices will go down as a result.

This will be especially useful for clients with data-intensive workloads, such as those associated with artificial intelligence (AI) or seasonal e-commerce (TCE). Depending on anticipated workloads, customers may add new workloads or switch between the conventional Aurora database and the I/O optimized version via the management panel, which can help keep expenses in check.


The release of AWS announced that the Amazon Aurora version marks a significant milestone in the evolution of database technology. By eliminating I/O costs and introducing advanced features, AWS empowers businesses to optimize their data storage systems for enhanced performance, scalability, and security. The revolutionary capabilities of Aurora set a new benchmark in the industry, providing organizations with the competitive edge they need to thrive in the digital age.
