Answer / Shailesh Kumar Singh

On-Demand instances in Amazon Web Services (AWS) are flexible, pay-as-you-go virtual servers that can be launched quickly and used for short-term workloads or unpredictable traffic patterns. Reserved instances are long-term commitments to reserve capacity at a lower price than on-demand instances for a fixed period of time. They can provide significant cost savings for applications with steady state, predictable usage.
