SAP RISE Deployment Options: Public vs Private vs Sovereign Cloud

SAP Private Cloud Deployment Options – Public vs Private Edition vs Sovereign

Introduction – Why Deployment Model Matters

Deciding how to deploy SAP in the cloud isn’t just a technical choice – it’s also a major business and contractual decision. SAP’s RISE offering provides multiple cloud deployment options, and each comes with different costs, flexibilities, and risks.

The model you choose will impact how much you can customize the system, how often it changes, what you pay, and what terms you’re locked into.

In other words, picking the right deployment model can mean the difference between a smooth cloud journey and a challenging one.

This guide breaks down the differences and helps you weigh these options (and negotiate the best deal) like an SAP licensing expert.

RISE Public vs Private Cloud

Public Cloud Edition (Multi-Tenant SaaS): This is SAP’s multi-tenant cloud offering – a shared environment where many customers use the same standardized S/4HANA system. The focus here is on standardization and simplicity.

SAP updates everyone’s system on a quarterly schedule, so you’re always on the latest version. The trade-off is limited customization: you cannot alter core SAP code or heavily modify processes. Instead, you adopt SAP’s best practices and use permitted extensions for any unique requirements.

The upside is faster deployment and the lowest cost option (resources are pooled for economies of scale).

Contracts for the public edition are largely fixed – you get a subscription with pre-defined services and little room to negotiate terms beyond basic pricing and duration.

Private Cloud Edition (Single-Tenant Managed Cloud): This is a dedicated instance of S/4HANA reserved for your organization, hosted by SAP or a hyperscaler. It offers much more control and flexibility.

You can retain your ABAP custom code, perform more extensive configurations, and even run industry-specific add-ons that the public cloud might not allow.

You also have a say in the upgrade schedule – updates aren’t pushed automatically without your agreement. For example, you might schedule major upgrades annually or during a quiet period for your business.

This model is ideal if you have complex integrations or unique processes that the public cloud can’t accommodate. Naturally, the cost is higher than the public edition because you’re paying for dedicated infrastructure and services.

On the plus side, a private edition contract is negotiable. You can work with SAP on specifics like how the system is sized, what service levels are offered, and even get credit for existing licenses (through conversion credits).

In short, the private edition gives you a tailored cloud environment at a premium price, with the flexibility to preserve what makes your business unique.

SLA and Update Cycles

The cadence of updates and how downtime is managed differ significantly between public and private options:

Public Cloud – Automatic Quarterly Updates: In the public cloud, SAP rolls out new features and fixes on a fixed quarterly cycle for all customers.

The benefit is continuous innovation – you’ll always have the latest capabilities without needing a big upgrade project. SAP sets a standard SLA (uptime/support) and uniform maintenance windows for all customers.

The downside is you give up some control. You must be prepared to test and refine your processes on a quarterly basis.

Frequent updates are manageable for simpler organizations, but can be challenging if you have many integrations or strict change controls. And remember, you cannot opt out of these quarterly updates – when SAP pushes it, it happens.

Private Cloud – Customer-Aligned Updates: In the private edition, updates are scheduled in consultation with you.

SAP provides improvements, but you decide when to apply them within an agreed window. This allows you to align major upgrades with your internal plans, significantly reducing the risk of disruption.

You also have the flexibility to schedule maintenance windows (e.g., downtime on weekends or off-hours) instead of following a fixed calendar. This yields a more stable environment – if an update needs extra testing due to custom code, you can delay it until you’re ready.

The trade-off is that you might not get new features as quickly as public cloud customers. Private edition users generally accept slower feature releases in exchange for greater stability and control. In short, the public cloud moves fast and drives innovation, while the private cloud moves at a controlled pace to minimize risk.

Sovereign Cloud (Sovereign Edition)

SAP’s Sovereign Cloud is a special variant of the private cloud for organizations with strict data residency and compliance requirements. It’s basically the private edition restricted to a specific country/region (using local data centers and staff) to meet local laws.

This is particularly relevant for government agencies and industries such as defense, banking, and healthcare, where regulations require that sensitive data remain within specific boundaries.

In a Sovereign Cloud scenario, your system is hosted under additional safeguards: data won’t leave the specified country/region, and access is restricted to vetted personnel in that locale.

These extra measures typically come with higher costs – often a defined surcharge on top of normal private cloud pricing (to cover things like dedicated infrastructure and compliance overhead).

There may also be some functional limitations (for example, certain services might be unavailable until they meet sovereignty standards).

Ensure SAP is transparent about the sovereign premium and clearly defines its responsibilities. From a contractual standpoint, you’ll sign addenda covering data residency and compliance.

Choose the sovereign option only if you truly need it – it’s the priciest and most restrictive model, but sometimes it’s the only way to comply with local laws. When you do, negotiate carefully to ensure compliance requirements are met without unnecessary costs.

Licensing & Contract Implications

The deployment model you choose also affects your licensing and contract flexibility:

• Public Cloud: This is a subscription service that bundles software, infrastructure, and support together. You typically pay per user (or similar metric) for access. Contracts are standardized, meaning you accept SAP’s cloud terms with little room for negotiation. SAP may offer conversion credits for on-premise licenses, but essentially, you’re signing a new subscription contract.
• Private Cloud: With a private edition, the contract is more customizable. You can negotiate specifics like how your system is sized (and how scaling is handled), maintenance timing, and even what additional components are included. Importantly, you should discuss how your existing SAP investments can be credited – many RISE deals allow you to offset costs by converting your existing maintenance into subscription credits (avoiding double-payment). Overall, you have more leverage: push for better SLAs, include exit options, and align the contract with your project timeline.
• Sovereign Cloud: This is typically an add-on to a private cloud contract that includes additional provisions. Expect a price uplift for the sovereign environment. It’s critical to confirm exactly how much extra you’re paying and what you’re getting for it (e.g., dedicated local support or compliance audits). The contract will have clauses ensuring data residency and local data handling. These contracts are the most restrictive – negotiate carefully to ensure compliance requirements are met without unnecessary costs or loopholes.

Public vs Private vs Sovereign at a Glance

Here’s a quick comparison of the three RISE deployment options:

Choosing the Right Deployment Model

Here are some general guidelines:

• Public Cloud – best for relatively standard processes and a need for speed and low cost. If you can adapt to SAP’s templates and have limited IT resources, the public edition offers quick value. Just be sure you can handle the quarterly update rhythm and the limited flexibility.
• Private Cloud – choose this if you have unique requirements or heavy integrations that a standard solution won’t support. This option lets you carry over vital customizations and control the timing of changes (useful if you have critical business periods or validation needs). You will pay more, but that premium buys you continuity for your specialized processes and a tailored environment.
• Sovereign Cloud – pick this only when regulations require it (for example, in government or defense projects where data must stay under a specific jurisdiction). It’s the most expensive option (often at least 15–20% more) and can come with limitations due to compliance needs. In these cases, the decision is driven by legal necessity rather than IT preference. Ensure SAP clearly outlines how it meets your compliance requirements and why the extra cost is justified.

Real-World Scenarios

To illustrate, here are a few example scenarios:

• Government Agency (Strict Data Laws): A national government department must move to S/4HANA, but is legally required to keep all data and systems within the country’s borders. Sovereign Cloud is the clear choice, and the premium cost is simply the price of compliance in this case.
• Global Manufacturer (Highly Customized ERP): A manufacturing conglomerate runs an SAP ERP with extensive custom ABAP programs and specialized add-ons. For them, the Private Cloud edition is essential. It enables a seamless transition to S/4HANA without compromising the unique capabilities that drive their business. They’ll budget for the higher subscription cost, justified by avoiding the disruption of redeveloping their complex custom solutions.
• Mid-Market Company (Standard Needs): A growing company with straightforward processes and a small IT team is implementing SAP for the first time. The Public Cloud edition is the most sensible choice. It offers rapid deployment, lower cost, and requires less IT oversight. For now, the public cloud ticks all the boxes of cost and simplicity for them.

FAQs

Q: Can we switch from Public to Private later if needed?
A: Yes, but it’s essentially a re-implementation with a new contract – not a simple switch. If you foresee this possibility, consider negotiating terms up front to ease a future transition.

Q: Is the Sovereign Cloud slower to get updates?
A: Often yes – updates roll out more slowly in a Sovereign Cloud to meet compliance, so that you may lag behind public cloud features.

Q: Can we use our existing SAP licenses to reduce RISE costs?
A: Not directly, but negotiate for credits – SAP can convert the value of your existing licenses into a discount so you don’t pay twice.

Five Expert Recommendations

1. Never leave the update policy vague. Get in writing how often and when SAP will update your system, and what control you have.
2. Leverage SAP’s urgency. Use SAP’s eagerness to move you off ECC (with its looming support deadlines) as leverage to get better pricing or terms, especially for the private edition.
3. Demand transparency on Sovereign fees. If Sovereign Cloud is on the table, insist SAP itemize the extra costs and justify each one – don’t pay a compliance premium without clarity.
4. Don’t pay twice for licenses. If you already own SAP licenses, negotiate conversion credits or BYOL terms in your private cloud deal to account for that value.
5. Choose with the future in mind. Don’t just pick the cheapest or easiest option for today – consider your growth and innovations over the next 5–10 years. The right choice will support your business as it evolves.
