Reserved instances are not actually physical instances, but a discount applied to the bill incurred from on-demand instances. AWS RDS reserved instance is one of the many other services that help you optimize your cloud cost.
Reserved instances are available in three payment options:
- No upfront (billing is done according to a discounted hourly rate)
- Partial upfront (some part of the cost paid in advance and rest of the remaining hours in the term are billed according to the applied discount)
- All upfront (Full payment done in advance without any additional cost)
Therefore, you can reserve your instances since it is one of the best cost optimization practices.
