Episode 99: On-Demand vs. Reserved vs. Spot Instances

In this episode, we provide a detailed comparison of On-Demand, Reserved, and Spot Instances, helping you decide which option is best for your AWS workloads. On-Demand Instances are the most flexible and allow you to pay for compute capacity by the hour or second, making them ideal for unpredictable workloads. However, they can be more expensive compared to other options. We’ll explain when to use On-Demand Instances for testing, development, or workloads with unpredictable traffic patterns, and how to manage costs by adjusting your usage.

Next, we’ll explore Reserved Instances, which offer significant savings for long-term, predictable workloads. We’ll discuss how Reserved Instances provide discounts in exchange for a one- or three-year commitment, and how to plan your capacity to maximize savings. Lastly, we’ll cover Spot Instances, which are ideal for flexible, fault-tolerant workloads that can tolerate interruptions. Spot Instances are much cheaper but come with the risk that AWS might reclaim capacity if demand for resources increases. By the end of this episode, you’ll be able to make informed decisions about which EC2 pricing model to use for your specific needs.
