:chart:Your AWS bill is about to change with new pricing for Aurora
Aurora's new IO-Optimized mode flips the economics
TL;DR
AWS is changing its pricing model for Aurora, making reads 25% faster without extra cost. But smaller databases may not benefit from the $0.20/GB-month premium.
Aurora's new IO-Optimized mode promises to boost read performance by 25% without incurring additional costs. However, this comes with a catch: only larger databases will see significant savings due to the $0.20/GB-month premium. If you're running Postgres on RDS or Aurora Serverless v2, pay attention – your AWS bill might change soon.
Key Points
Aurora's new IO-Optimized mode boosts read performance by up to 25%, outpacing RDS by a significant margin
The $0.20/GB-month premium only pencils out above ~100K read IOPS per instance, making it a worthwhile investment for high-traffic sites
Smaller databases may not see significant savings due to the new pricing model, with some users reporting no more than 5% cost reduction
Aurora Serverless v2 gets IO-Optimized mode automatically starting November 1, so be sure to monitor your performance and adjust as needed
IO-Optimized mode is available for all Aurora database engines, including PostgreSQL, but requires a minimum instance size of db.r5.xlarge
Why It Matters
If you're running Postgres on RDS or Aurora Serverless v2, the new pricing model could impact your AWS bill. Smaller databases might not see significant savings, but larger ones will benefit from faster read performance. For example, if you have a large e-commerce database with 500K read IOPS per instance, the $0.20/GB-month premium is likely to pay off.
