SAP S/4HANA Cloud Deployment of Choice
SAP S/4HANA can be deployed in a public cloud or private cloud.

A Public Cloud deployment is recommended if a customer has the ability and mindset for a transformational project, low landscape complexity, and can start with a clean system.
The implementation will include:
- A complete, modern, SaaS ERP solution with full public cloud benefits.
- The fastest path to innovation and lowest total cost of ownership (TCO).
- A clean Cloud ERP solution without converting old/legacy ERP processes and configurations.
- To reimagine business processes and take advantage of standardized best practices.
A Private Cloud deployment is recommended if a customer has plans for a long-term evolutionary journey to the cloud with high landscape complexity including mostly fragmented, highly customized systems.
The implementation will include:
- A rapid conversion of their existing SAP ERP/ECC environments to a modern, cloud-based architecture. A new implementation with a clean system is also possible.
- Full SAP S/4HANA on premise scope and functionality as a subscription and lower TCO based on the cloud model.
- Ability to safeguard prior investments including ECC customizations, configurations, and partner add-ons including SOLEXs and certified solutions.
- SaaS landscape at your own pace with the ability to extend and enhance as required.
Infrastructure Provider of Choice
A cloud software a service (SaaS) solution requires infrastructure to host the solution. Infrastructure refers to the physical server(s) where your software is installed. A building with many rooms full of these servers is called a data center. SAP has its own data centers, and we partner with other companies that provide infrastructure services, who we call, hyperscalers.
Our hyperscaler providers include: Microsoft Azure, Amazon Web Services, Google Cloud, and Alibaba Cloud. When customers use an Infrastructure as a Service (IaaS) provider, they do not have to buy the physical hardware or employ in-house experts to maintain it. The classic "on premise" concept refers to a customer purchasing and owning their own servers on company property, and installing and maintaining their software in these servers.

For the public cloud deployment, SAP is the default infrastructure provider. This enables us to offer customers the lowest TCO with a complete, packaged SaaS offering.
For the private cloud deployment, customers can choose their preferred infrastructure provider from our hyperscaler providers, SAP, or in special cases, the customer's own data center. These special cases are reserved for customers in regulated industries, public sector, or in countries with data residency requirements.
