RDS Read Replica Cost Reduction
Hi all,
In the past few days, we have profiled our RDS read replica instance and the usage of it. We have compiled the data that can be seen in this spreadsheet. Based on that data, we provide a recommendation and a general guideline that can help you to reduce cost for RDS read replica in production environment. For more details, you can read it in this confluence page.
Recommendation
- Please follow our recommendation to downscale/decommission your RDS read replica instance.
- Kindly do analysis on your side to see if our recommendation can be fitted for you. We only give recommendation based on the data we have but we are surely lack of some data e.g: business requirements.
- Red highlighted row means we recommend to decommission the instance. Meanwhile, yellow highlighted row means we recommend to downscale the instance following the "Recommendation" column.
- If your instance isn't provided any recommendation, it means we can't decide any recommendation for you but you can decide what you can do to your instance by following the general guideline provided in the confluence page.
- Please analyse and monitor your instance before and after you change the instance type
- Please update the "Action Item" and "Status" column by the end of next Thursday, 30 April 2020. We would like to know what your plan/decision is to decide our next plan.
Should you have any questions, comments or concerns, kindly discuss it in the thread. Thank you!
