Episode 57: EC2 Purchasing Options (On-Demand, Reserved, Spot, Savings Plans)

In this episode, we cover the different EC2 purchasing options available to help you optimize costs and flexibility when using AWS. EC2 offers four main purchasing models: On-Demand Instances, Reserved Instances, Spot Instances, and Savings Plans. We’ll start by explaining On-Demand Instances, which allow you to pay for compute capacity by the hour or second, with no long-term commitments. This model provides maximum flexibility but can be more expensive if you have long-running workloads.

Next, we’ll dive into Reserved Instances, which allow you to commit to using EC2 instances for a one- or three-year term in exchange for significant discounts compared to On-Demand pricing. Spot Instances provide even deeper discounts by allowing you to bid for unused EC2 capacity, but they can be interrupted if AWS needs the capacity back. Finally, we’ll discuss Savings Plans, which provide flexible pricing for long-term compute usage in exchange for a commitment to a consistent amount of usage over one or three years. By the end of this episode, you’ll understand how to choose the right purchasing option to balance cost, flexibility, and capacity for your workloads.
