Difference between reserved instance and on-demand instance

 

Reserved instance, spot instance and on-demand instance use-cases

Reserved Instances provide you with a significant discount compared to On-Demand instance pricing. In addition, when Reserved Instances are assigned to a specific Availability Zone, they provide a capacity reservation, giving you additional confidence in your ability to launch instances when you need them.

Standard Reserved Instances provide you with a significant discount compared to On-Demand instance pricing and can be purchased for a 1-year or 3-year term. The average discount off On-Demand instances varies based on your term and chosen payment options (up to 40% for 1-year and 60% for a 3-year term). Customers have the flexibility to change the Availability Zone, the instance size, and networking type of their Standard Reserved Instances.

Convertible Reserved Instances provide you with a significant discount compared to On-Demand Instances and can be purchased for a 1-year or 3-year term. Purchase Convertible Reserved Instances if you need additional flexibility, such as the ability to use different instance families, operating systems, or tenancies over the Reserved Instance term.

Amazon EC2 On-Demand Instances Although it is suitable to run non-interruptible workloads for a period of three years, it entails a higher running cost compared to Reserved or Spot instances. In fact, this is actually the most expensive type of EC2 instance and not the cheapest one.
