Scheduled Reserved Instance: Perfect for workloads with predictable and recurring schedules (like 12 hours on Sunday). This is cost-efficient and ensures uninterrupted instances.
Convertible Reserved Instance: Allows flexibility to change instance types, sizes, or OS during the term. However, they are not ideal for short, predictable schedules like 12 hours on Sunday. Scheduled Reserved Instances are a better fit.
Spot Instances can be interrupted at any time. They do not guarantee uninterrupted operations.
