Flexible pricing model offering discounts in exchange for consistent usage commitment, without being tied to specific instance types. Like a gym membership that works at any location in the chain.
A company commits to $1000/hour of compute spending and gets 30% discounts across EC2, Fargate, and Lambda regardless of which services they use.
All four are commitment-based discount models. AWS and Azure offer spend-based compute savings plans that apply broadly across eligible compute usage. GCP CUDs provide discounts for committing to a level of resource usage (often vCPU/RAM or specific services) for a term. OCI offers discounts tied to committed spend (often via Universal Credits commitments) rather than reserving a specific instance.
