Explanation/Reference:
Explanation:
The AWS Reserved Instance provides the user with an option to save some money by paying a one-time fixed amount and then save on the hourly rate. It is advisable that if the user is having 30% or more usage of an instance per day, he should go for a RI. If the user is going to use an EC2 instance for more than 2200-2500 hours per year, RI will help the user save some cost. Here, the instance is not going to run for less than 1500 hours. Thus, it is advisable that the user should use the on-demand pricing.
