I am planning to buy 5 x t3a.xlarge reserved instances for 3 years.
After the 3rd year I am planning to buy 3 x t3a.2xlarge instances to provide reservation for the t3a.xlarge instances whose reservation is still running.
Will the t3a.2xlarge provide discount to the t3a.xlarge instances?
Does this apply to RDS for db.t3.xlarge?
