Summary
Our focus in this chapter was optimizing compute services on AWS. We spent the first section of the chapter diving deep into billing mechanisms that benefit steady-state workloads. RIs and SPs are perfect for covering workloads that require compute resources to be on consistently throughout the year.
We unpacked how billing works for both options and concluded that SPs are preferable to RIs because of their flexibility and lower maintenance requirements. Because both options offer the same discount rates, there is little reason to choose RIs over SPs. Cost Explorer provides reports and recommendations to help you with your RI/SP purchasing strategy.
We also explored Spot as another option for compute services. Spot is ideal for flexible and interruptible workloads because of the deep discount AWS provides. However, we must be mindful of how we architect workloads using Spot due to the interruptible nature of Spot resources. We reviewed mechanisms to keep our workload...
