Question

My cost in RDS Services (specifically ExtendedSupport: Yr1-Yr2: MySQL5.7) went up from $0 in february to $178.19 in March and $254.34 in April. And I have no idea why.
I have 4 Databases with MySQL5.7 Engine but I do not know which one is causing the rise in expenses. In the meantime, I will pause all de DB untill I can solve this.
Please help me so I can learn how to check which is the instance causing the rise in my costs (and in how much each one contributes).

Answer

Oleksii, thank you!

Its good to know that. How can I move them to a free tier? And how can I check how much CPU consumed each of my databases?

Best regards,
Fernando.

Answer

The RDS Extended Support price you are charged depends on the MySQL version, AWS Region, and the number of calendar years since standard support expired for that version.

https://aws.amazon.com/rds/mysql/pricing/#Amazon_RDS_Extended_Support_costs

If you are running a DB instance on RDS for MySQL 5.7, this version reaches end of standard support on February 29, 2024. If you are deployed in US East (Ohio), you will be charged $0.100 per vCPU-hr between March 1, 2024 to February 28, 2026. Starting March 1, 2026, you will be charged $0.200 per vCPU-hr.

Verify that the instances haven't been upgraded or changed.

If you are still unable to determine the cause of the cost increase, consider opening a support ticket with AWS. They can provide more detailed insights into billing issues and specific charges.
