AWS EC2 On-demand capacity reservation is another new feature has been announced recently. This feature mainly focusing the customers who want to use a specific instance type on a particular availability zone for a long or short period. We just tried it and wanted to explain about how to use this properly.
If you are running any massive batch workload on a particular time frame with high-end instance type, then you can think about this feature. (another choice is Spot instances, but im looking from the instance type perspective).You are re-deploying the entire stack from Cloudformation, and you are confident about the instance type then you can reserve the instance type before launching the stack and make the reservation until your next deployment. If you know any other use cases, please comment below.
