Converting from rds on-demand to rds reserved instance #174

Closed yasinkayade closed 1 year ago

yasinkayade commented 2 years ago

Hi,

I use aws rds postgresql to store data (rds on demand instance type). Is it possible to convert it to a reserved instance without creating a new instance via CLI or console? On the internet there is pretty much info about ec2, but cannot see about rds.

Hello, from closely reading this page, https://aws.amazon.com/rds/reserved-instances/#2, I believe the answer is 'yes.' As I understand this, you can create a reservation using the same specifications (DB instance class size) as your on-demand instance. After you create the reservation, the new billing method (reserved) is automatically applied to your instance. You can't delete a reservation after you create it, however. Rather, you need to delete the instance associated with the reservation.

See this section of the RDS User Guide for more information about reserved instances. https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_WorkingWithReservedDBInstances.html

In the RDS Console (left-hand navigation menu) you see Reserved instances. Start there to create a reserved DB instance. Here's an example that shows creating a reservation using the "No upfront" option. reserved_instances_create_page

Hope this helps.
