AWS credit with Spot instance

Yes, AWS credits are valid for use with Spot Instances! In fact, using Spot Instances is a great way to stretch your AWS credits further as they are significantly cheaper than On-Demand Instances.

Points to note:

Credits don't cover upfront costs: Keep in mind that AWS credits cannot be applied to upfront fees associated with certain services like Reserved Instances.

Spot Instances can be interrupted: Since Spot Instances are unused capacity, AWS can reclaim them if needed. This means your instance might be interrupted, so make sure your workload is tolerant of such interruptions.
