Choosing between Cloud ERP and a traditional on-premise ERP system is now one of the most important strategic IT decisions for mid-sized companies. The decision is no longer simply about where the software is hosted. The chosen operating model also affects investment costs, speed of innovation, IT workload, data security, and a company’s long-term competitiveness.
In this article, you will learn about the differences between the two models, their respective advantages and disadvantages, and which operating model is suitable for which business scenarios. We also explain why SAP Cloud ERP, in particular, is increasingly establishing itself as a future-proof solution for many mid-sized companies.

What is Cloud ERP?
A Cloud ERP system is enterprise software delivered entirely over the internet. The provider handles operations, infrastructure, maintenance, updates, and security measures. Companies access their ERP solution through a browser or apps and usually pay for it through a subscription model (Software-as-a-Service).
Typical cloud-based ERP solutions include:
- SAP Cloud ERP
- Microsoft Dynamics 365
- Oracle Fusion Cloud ERP
Unlike traditional ERP systems, companies do not need to build or operate their own server infrastructure.
Cloud-based ERP is becoming increasingly important, especially for mid-sized companies. According to the Bitkom Cloud Report 2025, 90% of German companies now use cloud applications. At the same time, 47% of all IT applications are already operated from the cloud, while 62% of companies state that they would no longer be able to operate effectively without cloud solutions. (Cloud Report 2025 – Status Quo und Trends in Wirtschaft und Politik | Bitkom Research)
This development clearly shows that the cloud is no longer a vision of the future; it is increasingly becoming the standard.
What does on-premise ERP mean?
With an On-Premise-ERP system, the software is installed and operated on the company’s own servers.
The company itself is responsible for:
- Hardware
- Server operations
- Backups
- Security updates
- Release upgrades
- Maintenance
- Databases
- Monitoring
This operating model was the standard for decades and remains widespread today, particularly in long-established SAP environments.
Its greatest advantage is maximum control over infrastructure and systems. At the same time, however, it requires considerable operational and administrative effort.
Cloud ERP vs. On-Premise: The Key Differences
| Criterion | Cloud ERP | On-Premise ERP |
|---|---|---|
| Investment | ongoing costs (subscription) | high upfront investment |
| Infrastructure | provided by vendor | own data center |
| Updates | automatic | separate internal project |
| Maintenance | vendor | internal IT team |
| Scalability | very high | limited |
| Availability | global | dependent on the corporate network |
| Innovation | continuous | release-dependent |
| Implementation time | usually significantly shorter | often longer |
The biggest difference is not the technology itself, but the operating model.
While on-premise primarily offers control, cloud-based ERP focuses on standardization, automation, and continuous innovation.
Costs: Upfront Investment or Ongoing Operating Model?
Cost is one of the most common decision criteria.
Many companies initially assume that an on-premise system is less expensive because there are no recurring license costs.
However, this view does not tell the whole story.
Actual operating costs also include:
- Server
- Databases
- Hardware replacement
- Backup infrastructure
- Monitoring
- Maintenance contracts
- Energy
- Internal administrators
- External service providers
- Upgrade projects
A cloud-based ERP model shifts these costs into a transparent monthly operating model.
This results in:
- lower initial investment
- predictable operating costs
- no hardware investments
- lower maintenance costs
Mid-sized companies in particular benefit from this greater predictability.
Flexibility and Scalability
Companies are constantly changing.
New locations.
New employees.
New legal entities.
New markets.
A modern ERP system must support these changes.
Cloud-based ERP makes it possible to add users, storage, or functionality at short notice.
With traditional on-premise systems, growth often means:
- new servers
- additional databases
- larger storage systems
- new infrastructure projects
This difference is particularly significant for companies expanding internationally.
Security: Is Cloud ERP Really Secure?
Many companies still associate on-premise systems with greater security.
In reality, this perception has changed significantly in recent years.
Professional cloud providers invest billions in:
- Data centers
- Encryption
- High availability
- Security Monitoring
- Disaster Recovery
- Certifications
- Penetration testing
For mid-sized companies, achieving this level of security internally is often not economically feasible.
The Bitkom Cloud Report 2025 also shows which criteria companies prioritize when selecting a cloud provider: IT security, data protection, compliance, as well as performance and stability are each considered crucial by 99% of the companies surveyed.
The key question is therefore less about Cloud oder On-Premise, and more about:
How professionally is the respective infrastructure operated?
Updates and Innovation
One of the biggest differences lies in software updates.
On-Premise
New versions must be:
- planned
- tested
- installed
- migrated
- documented
completed.
This often results in upgrade projects lasting several months.
As a result, companies often remain several versions behind the latest software release.
Cloud ERP
This model takes a different approach.
New features are delivered regularly.
As a result, companies continuously benefit from:
- new ERP features
- AI support
- Automation
- Security updates
- regulatory changes
- performance improvements
SAP’s cloud-based ERP offering, in particular, continues to evolve without every update turning into a major project.
Maintenance and Internal IT Workload
An on-premise system requires permanent internal resources.
Typical tasks include:
- Server administration
- Database maintenance
- Monitoring
- Backup
- User administration
- Patch management
- System maintenance
However, mid-sized companies are finding it increasingly difficult to recruit qualified SAP Basis or infrastructure specialists.
A cloud-based ERP solution significantly reduces this workload.
Internal IT teams can focus more on:
- Digitalization
- Process optimization
- Data quality
- Business departments
- Innovation
instead.
Instead of operating infrastructure, IT becomes a business partner.
Cloud ERP and SAP: Why Standardization Is Becoming Increasingly Important
The ERP landscape is currently undergoing fundamental change.
While traditional ERP systems were heavily customized, SAP is now deliberately pursuing a different approach.
With SAP’s cloud ERP offering, standardized business processes, regular innovation, and a so-called Clean Core are at the center of the strategy.
Custom extensions are implemented outside the ERP core, for example via the SAP Business Technology Platform (SAP BTP).
The result:
- lower maintenance effort
- greater upgradeability
- faster innovation
- less technical debt
Mid-sized companies benefit particularly from this approach because they can adopt new functionality more quickly and reduce the long-term effort required for custom developments.
When Is Cloud ERP a Good Fit?
The model is particularly suitable for companies that
- want to grow,
- are establishing international locations,
- want to reduce the burden on their IT teams,
- want to establish modern processes,
- want to use AI and automation,
- want to future-proof their ERP landscape.
Companies with limited internal IT resources benefit particularly from this operating model.
When Can On-Premise Still Make Sense?
Despite all the advantages, there are situations in which on-premise can still make sense.
For example, when
- extensive custom developments are already in place,
- regulatory requirements mandate self-hosting,
- significant infrastructure investments have already been made,
- a large internal SAP Basis team is available.
Hybrid scenarios can also make sense.
Gartner expects that by 2027, around 90% of companies will adopt hybrid cloud strategies that combine cloud and on-premise systems.
Why Is the Market Clearly Moving Toward the Cloud?
The ERP strategies of many companies are currently changing fundamentally.
In addition to cost efficiency, speed of innovation, AI, and automation now play a decisive role.
Gartner also forecast worldwide public cloud spending to grow to USD 723.4 billion in 2025, an increase of 21.5% compared with the previous year. (Gartner Forecasts Worldwide Public Cloud End-User Spending to Total $723 Billion in 2025)
Cloud-based ERP is therefore increasingly becoming the standard for modern enterprise software.
Not because on-premise is inherently bad.
But because companies today need to respond to market changes much faster than they did ten years ago.
Conclusion
The decision between cloud-based ERP and on-premise ERP is not purely a technical question; it is a strategic decision that shapes the future of your company.
While on-premise remains justified in certain scenarios, many mid-sized companies benefit from a modern cloud-based ERP system: lower barriers to entry, predictable costs, automatic updates, high scalability, and continuous innovation. SAP’s cloud ERP solution in particular demonstrates how standardization and flexibility can be combined without neglecting security or compliance requirements.
Companies planning a new ERP implementation or modernization should therefore consider not only their current requirements but also their future development. A future-ready ERP system must grow with the company, integrate new technologies such as AI, and remain economical to operate over the long term.

FAQ
A cloud-based ERP system is provided as a service over the internet and operated by the vendor. With on-premise, the company installs and operates the ERP software itself on its own infrastructure.
Yes. Leading cloud providers meet high security, data protection, and compliance standards and continuously invest in protecting their data centers. For many mid-sized companies, this level of security exceeds what they can achieve with their own IT infrastructure.
SAP’s cloud-based ERP solution offers automatic updates, high scalability, integrated innovations such as AI capabilities, standardized processes, and lower operating and maintenance effort compared with traditional on-premise systems.
Not necessarily. Although the licensing models differ, hardware, operations, maintenance, upgrades, and internal IT resources generate significant ongoing costs for on-premise systems. A comprehensive assessment of total cost of ownership (TCO) is therefore essential.
Cloud-based ERP is particularly suitable for mid-sized companies that want to reduce the burden on IT, grow faster, use modern technologies, and remain flexible over the long term.
