Azure MACC vs AWS EDP vs Google CUD: Cloud Commitment Contracts Compared

Why Cloud Commitment Contracts Have Become a Strategic Priority

Multi-cloud is now the enterprise default. According to Gartner's 2025 cloud survey, 87% of enterprises use two or more cloud providers, with 43% using three or more. What was once an exception — running workloads across Azure, AWS, and Google Cloud simultaneously — is now routine. And with multi-cloud normalisation comes a new class of commercial challenge: managing commitment contracts across multiple vendors simultaneously, without allowing any single vendor to capture more commitment than the organisation's actual trajectory justifies.

The three major cloud commitment vehicles — Azure's Microsoft Azure Consumption Commitment (MACC), AWS's Enterprise Discount Programme (EDP), and Google Cloud's Committed Use Discounts (CUD) — share a common purpose but differ substantially in structure, flexibility, negotiating dynamics, and the strategic leverage they create for the buyer. Understanding those differences is prerequisite to negotiating any one of them effectively, and essential for managing a multi-cloud commitment portfolio that maximises discount while protecting flexibility.

This analysis focuses on the commercial and contractual dimensions of each programme, with particular emphasis on how each creates negotiating leverage and how multi-cloud buyers can use the existence of competing commitment discussions to improve outcomes with all three vendors. The full Azure MACC mechanics are covered in depth in the dedicated MACC leverage guide; this article provides the comparative cross-vendor context.

Azure MACC: The Microsoft Cloud Commitment

The Microsoft Azure Consumption Commitment is Microsoft's primary mechanism for securing enterprise cloud revenue. Under MACC, the organisation commits to consuming a defined dollar amount of Azure services over a 1–5 year period. In return, Microsoft provides a credit balance that draws down against eligible Azure consumption, and — when properly negotiated — commercial discounts on the Azure rate card and EA-level commercial concessions.

MACC Structure and Drawdown

A MACC commitment is typically structured as an annual commitment with quarterly minimum drawdown requirements, though the specifics are negotiable and vary significantly from the standard terms. The commitment is denominated in USD and can draw down against most Azure services — though certain marketplace services, non-Azure Microsoft services, and some preview-tier services are excluded from eligible consumption.

MACC credits are applied automatically against eligible Azure invoices. The billing mechanics mean that if monthly Azure consumption exceeds the pro-rated MACC drawdown rate, pay-as-you-go charges appear on the invoice alongside MACC credit drawdown. If consumption is below the commitment rate, the deficit accumulates and must be consumed by the end of the commitment period or the shortfall is invoiced.

The risk of under-consumption — committing more than the organisation actually consumes — is the primary commercial risk in MACC negotiations. Microsoft's account team will almost always propose a MACC at the high end of plausible consumption, because the minimum commitment billing protects Microsoft's revenue regardless of actual usage. Negotiating the MACC size down to a defensible consumption forecast with upside optionality is one of the most important outcomes an independent advisor delivers.

MACC as EA Leverage

The commercial value of a MACC extends beyond the direct Azure credit. A large MACC commitment creates internal Microsoft approval justification for Azure rate card discounts, M365 commercial concessions, and overall EA terms that are not available without such a commitment. This linkage — between MACC size, Azure discounts, and EA-wide commercial terms — is covered in detail in the MACC leverage analysis and the multi-cloud white paper.

AWS Enterprise Discount Programme: The AWS Equivalent

The AWS Enterprise Discount Programme (EDP) is the closest AWS equivalent to MACC. Under EDP, an organisation commits to a minimum spend on AWS services over a 1–5 year period in exchange for a percentage discount off the AWS pay-as-you-go rate. Unlike MACC, which provides a credit balance, EDP provides a discount applied to consumption directly — there is no credit balance that can be under-drawn.

EDP Discount Structure

EDP discounts are negotiated as a percentage off the AWS list price, applied to all eligible AWS service consumption during the commitment period. The discount rate is a function of commitment size and duration, with larger and longer commitments yielding higher discounts. Typical enterprise EDP discounts range from 10–25%, with outliers at both ends depending on the organisation's consumption profile and alternative-provider leverage.

EDP discounts are applied before Reserved Instance and Savings Plan discounts — meaning an EDP discount of 15% is applied to the pre-RI list price, with RI discounts then applied on top of the discounted EDP rate. This stacking mechanism means the effective savings from combining EDP and RI are additive, potentially reaching 60–75% versus pay-as-you-go for stable committed workloads.

EDP vs MACC: Structural Differences

The key structural difference between EDP and MACC is the billing mechanism. MACC operates as a credit balance — you pay the committed amount and draw it down against consumption. EDP operates as a rate discount — you pay for what you consume at a discounted rate, with a minimum spend commitment that may result in shortfall billing if consumption falls below the committed level.

From a cash flow perspective, MACC's upfront credit structure can be advantageous for organisations with capital budget availability — the MACC credit is pre-purchased, reducing period-over-period operating expenditure. EDP's consumption-discount structure is typically better for organisations with opex-constrained budgets or uncertain consumption forecasts.

Google Cloud CUD: The Google Commitment Mechanism

Google Cloud's Committed Use Discounts (CUD) differ from both MACC and EDP in a fundamental way: they are primarily a technical commitment mechanism rather than a commercial contract mechanism. Standard CUDs — available at resource level through the Google Cloud Console — provide 1- or 3-year commitments to specific compute resources in exchange for 37–55% discounts. These are analogous to Azure Reserved Instances or AWS Reserved Instances, not to MACC or EDP.

The Google equivalent of a commercial commitment contract — comparable to MACC or EDP — is the Google Cloud Platform Commitment (GCP Commitment), negotiated directly with Google Cloud sales as part of an enterprise commercial agreement. These are sometimes called Flexible CUDs or are structured as consumption commitments within a Google Cloud agreement, and are not available through the self-service Console.

GCP Commercial Commitments vs Standard CUD

Standard GCP CUDs are resource-level commitments (vCPU, memory) in specific regions, providing fixed discounts that are determined by the commitment type (general-purpose, memory-optimised, accelerator-optimised) rather than negotiated commercially. They function similarly to Azure RIs and can be combined with Google's Sustained Use Discounts (SUDs) for additional savings on eligible compute.

Negotiated GCP commercial commitments function more like MACC or EDP — they involve a minimum spend commitment over a multi-year period in exchange for rate card discounts and commercial terms. These are less structurally standardised than Azure MACC or AWS EDP, which means they are more customisable but also more opaque and harder to benchmark. Google's commercial teams are significantly less process-driven than Microsoft's in this area, which creates more room for negotiation but also more risk of unfavourable structure if the buyer lacks experience.

Head-to-Head: MACC vs EDP vs CUD

Multi-Cloud Leverage: Using Competing Commitments to Improve All Three

The most underutilised aspect of multi-cloud commercial strategy is the leverage that commitment discussions with one vendor create in negotiations with the others. This leverage is real, quantifiable, and consistently underexploited by organisations that negotiate each vendor relationship in isolation.

The Mechanics of Cross-Cloud Leverage

Cloud commitment negotiations are ultimately competitions for share of wallet. When Microsoft's account team understands that the organisation is in active EDP or GCP commitment discussions, the internal commercial justification for offering better Azure MACC terms — higher rate card discount, more flexible drawdown terms, shorter minimum commitment period — becomes defensible within Microsoft's approval process.

The leverage works because cloud vendors' account team incentives are structured around share-of-wallet growth, not just absolute revenue. Offering a 20% Azure rate card discount to win or retain cloud spend that might otherwise go to AWS is internally justifiable in a way that offering a 20% discount with no competitive context is not.

How to Structure Multi-Cloud Commercial Negotiations

Effective multi-cloud commitment negotiation requires three things that most organisations lack: independent visibility into the commercial norms for each vendor, the ability to run concurrent negotiation timelines without creating commitments prematurely, and a credible alternative posture with each vendor.

The credible alternative posture is the most difficult to establish. Telling Microsoft's account team that "we might put more workloads on AWS" is not credible if Microsoft can see from the MACC drawdown that Azure usage is growing consistently. The posture is credible when there is genuine architectural optionality — workloads that could run on either platform — and when the organisation has demonstrated willingness to make architecture decisions based on commercial terms.

For organisations with genuine multi-cloud architecture, the starting position for any cloud commitment negotiation should be explicit acknowledgement that the commitment structure being negotiated will determine workload allocation decisions. This positions the commitment discussion as a commercial competition rather than an administrative process — which is exactly the frame that unlocks better commercial terms from all three vendors.

Three Traps to Avoid in Cloud Commitment Negotiations

Trap 1: Committing Before Negotiating

The most common mistake enterprise buyers make in cloud commitment negotiations is accepting the vendor's proposed MACC, EDP, or CUD terms and committing before negotiating commercial terms. Once the commitment is signed, leverage evaporates. The vendor has the revenue certainty they sought; they have no commercial reason to offer rate card discounts that they could have withheld until signing.

The correct sequence is: receive the proposal, evaluate it, open a commercial negotiation, and sign only after commercial terms — including rate card discounts, minimum commitment adjustments, and drawdown flexibility provisions — have been agreed in writing.

Trap 2: Committing at the Maximum Plausible Consumption

Cloud account teams propose commitment levels at the top of the plausible consumption range because minimum commitment billing protects their revenue. Buyers who accept the proposed commitment level and subsequently under-consume pay for the shortfall — effectively paying full price for cloud services they did not consume. The correct commitment level is the floor of the organisation's credible consumption range, with contractual provisions for upward adjustment if consumption exceeds forecast.

Trap 3: Treating the Commitment as a Procurement Exercise

Cloud commitments that are managed as procurement transactions — review, approve, sign — never achieve the commercial terms available through genuine negotiation. The organisations that achieve best-in-class outcomes treat cloud commitments as strategic commercial negotiations, with executive sponsorship, competitive positioning, and independent advisory support. The financial stakes justify this treatment: a £20M cloud commitment negotiated at 15% better commercial terms is a £3M improvement — from the same spend, with no change to technical architecture.

For Azure specifically, the interaction between MACC negotiation and the broader EA renewal — including M365 licensing, Software Assurance, and Copilot commercial terms — is covered in the Complete Guide to Microsoft EA Negotiation and our EA Negotiation advisory service.

For Azure-Primary Organisations: The MACC Priority

Organisations whose primary cloud is Azure — typically those with significant Microsoft 365 deployments, on-premises Microsoft infrastructure, or enterprise-wide Microsoft product commitments — have a unique commercial dynamic. The MACC is not just an Azure commitment; it is part of a broader Microsoft commercial relationship that encompasses the EA, SA, M365, and increasingly Copilot.

For these organisations, the MACC negotiation should be embedded in the EA renewal process rather than conducted as a separate Azure commercial discussion. The leverage is maximised when Microsoft sees the total commercial relationship at risk — not just the Azure component. Organisations that negotiate the EA and MACC separately give Microsoft the ability to manage the commercial economics of one to offset concessions on the other. Negotiating them together prevents this dynamic.
