EDP vs MACC vs CUD: AWS, Azure and Google Compared

EDP vs MACC vs CUD is the comparison every enterprise faces before committing serious spend to a hyperscaler. The three programs look similar on a slide and behave very differently under pressure. This page lays them side by side from the buyer seat so you can see where each one helps you and where each one bites.

EDP vs MACC vs CUD at a glance

The AWS Enterprise Discount Program, the Microsoft Azure Consumption Commitment, and Google Committed Use Discounts share one idea. You promise spend, you get a discount. Underneath, the mechanics diverge in ways that decide your real risk. As of June 2026, the headline differences sit in how each handles unused spend, term length, and flexibility.

AWS EDP is a spend commitment over a 1 to 5 year term that unlocks tiered discounts scaling with the committed amount, typically from around one million dollars of annual spend. It stacks on top of Reserved Instances and Savings Plans, and overcommitment leaves a shortfall you must pay. Azure MACC commits you to a fixed dollar amount of Azure and Marketplace eligible consumption over the term, tied to the Microsoft Customer Agreement or an Enterprise Agreement, and unused commitment is generally lost. Google offers resource based and spend based Committed Use Discounts over 1 to 3 years, plus automatic Sustained Use Discounts that need no commitment at all.

The practical lesson is that the headline discount tells you little on its own. What decides the value of EDP vs MACC vs CUD is how each program treats the spend you do not use, how long it locks you in, and how much of your bill actually qualifies for the discount. Read those three things first and read the percentage second, because a deep rate on a narrow, rigid commitment can be worth far less than a modest rate on a broad and flexible one.

How each program penalises a miss

This is where EDP vs MACC vs CUD matters most. Under AWS EDP, falling short of the committed spend leaves a shortfall you pay anyway, so an aggressive ramp is the trap. Under Azure MACC, unused commitment is generally forfeited at term end rather than refunded or rolled over, so the trap is committing a fixed amount you cannot fully consume.

Google splits the risk. Resource based CUDs bill for the committed capacity whether or not you use it, which punishes committing to instances a workload may outgrow or retire. Spend based CUDs are more flexible across instance types. Sustained Use Discounts carry no commitment and so no penalty, but they do not double stack with CUDs on the same resource, as of June 2026.

Which program protects the buyer best

No program is buyer friendly by default. Each is priced to favour the seller, and each can be shaped in negotiation. The protective moves are consistent across all three. Commit to the floor of your confident usage, keep the ramp behind your forecast, broaden eligible spend, and strip out or diary any auto renewal.

GCP gives the most built in flexibility through automatic Sustained Use Discounts and instance flexible spend based CUDs, which suit volatile estates. AWS EDP rewards scale and stacks cleanly with Reserved Instances and Savings Plans, which suits a large, stable estate that can also optimise underneath. Azure MACC can deliver strong value when Marketplace inclusion is negotiated, but the lost use rule makes right sizing essential. The right choice follows your workload predictability, not the seller pitch.

How to run the comparison for your own deal

Start from your real consumption, not the provider forecast. Model committed spend against a conservative flat year, then test each program against that floor. Price the effective discount after exclusions, not the headline rate, and weigh the cost of lock in across a multi year term that removes future leverage.

Benchmark all three even if you intend to stay single cloud, because a credible alternative is leverage. An independent review paid only by the buyer can pressure test the numbers and the contract language before you sign.

How term length changes the EDP vs MACC vs CUD decision

Term is where the three programs feel most different over time. AWS EDP can run up to five years, which suits a buyer with a stable, growing estate that wants to lock a deep tier, but a five year term also removes future leverage for a long stretch. As of June 2026, the discount scales with the committed amount, so the temptation is to commit big and long. Resist it unless the underlying usage is genuinely predictable.

Azure MACC is tied to the term of the Microsoft Customer Agreement or Enterprise Agreement, so the commitment lives inside a wider contract you are also negotiating. That can help, because Marketplace inclusion and broader concessions can be traded across the whole agreement, but it also means the commitment is harder to isolate and right size on its own.

GCP committed use discounts run one to three years, the shortest of the three, and pair with automatic Sustained Use Discounts that carry no term at all. For a buyer who values the option to change course, that shorter horizon is itself a form of protection. The right term is the one that matches how far ahead you can honestly forecast, not the one that maximises the headline discount.

Reading the three programs against your own estate

The comparison only resolves once you map it onto your real spend. A buyer running a large, steady production estate on AWS will weigh the EDP tiers against years of consistent usage and may commit confidently. A buyer mid migration, refactoring workloads to run leaner each quarter, is far safer with GCP flexibility or a conservative MACC sized to the floor of consumption.

Mixed estates complicate the picture. Many enterprises run primary spend on one cloud and meaningful workloads on another, which raises the single cloud versus multicloud commitment question. Committing deeply on every provider multiplies your overcommitment risk, so the disciplined move is to commit only where usage is predictable and keep the rest flexible.

Whichever program leads, the protective principles hold. Commit to the floor, ramp behind the forecast, broaden eligible spend, price the effective discount after exclusions, and strip or diary any auto renewal. The program is the vehicle. The discipline is what keeps the commitment from becoming a liability.
