Quickly understand reserved instance before purchasing from here.
If you’ve purchased a on demand EC 2 instance and later realized that it would run for a course of time(for ex. 1 year,2 year), you can convert it into reserved instance to save few bucks. Remember reserved instance is just a pricing feature, and no actual conversion is done to your instance.
Here we go -
- The following details of the on-demand instance (which you are reserving) will be required – Platform,Instance Type,Availability Zone.
- Click on the Purchase Reserved Instance Button in your AWS console.
- Click on search after selecting the appropriate details.
- Offering Type -
Light Utilization RI’s – Lowest upfront price,ideal for periodic workloads that only run for couple of hours a day.
Medium Utilization RI’s – Higher upfront price than Light Utilization RIs, but a much lower hourly usage fee,best suited for workloads that run most of the time, but have some variability in usage.
Heavy Utilization RI’s – Highest upfront price,lowest hourly rate,,suitable for instance that run 24 hours.
- Here you go,you can see your purchased instance in the reserved instance tab on left side of the AWS console.
Congratulations ! You just saved some bucks.
