In December 2020, SAP announced it would end support for the SAP ECC by 2027. There will be no further extensions this time, according to SAP CEO Christian Klein. This change will have a significant impact, particularly for organizations still using the SAP Business Suite 7.
According to various Gartner reports, over 50% of SAP ECC customers have yet to migrate to SAP S/4HANA. If your organization is among them, it’s crucial to start planning your migration now. SAP experts estimate that it will take around 2-3 years to complete the migration to SAP S/4HANA.
As you plan the migration, it’s important to consider various factors that can significantly impact your business. One key consideration is choosing between the SAP S/4HANA private cloud and SAP public cloud.
What is SAP S/4HANA Public Cloud Edition?
SAP Public Cloud is a cloud-based deployment model offered by SAP that utilizes a “multi-tenant architecture,” where multiple customers share the same software instance and infrastructure while keeping their data secure and isolated.
It is designed to provide standardized processes, rapid implementation, and automatic updates, making it a cost-effective solution for businesses looking to adopt enterprise resource planning (ERP) solutions quickly.
It offers a subscription-based pricing model and includes pre-configured best practices tailored for specific industries. It is managed entirely by SAP, covering infrastructure, security, and maintenance, allowing companies to focus on their core business operations without the need for extensive IT overhead.
Key characteristics include quarterly updates managed by SAP, limited customization options, and a lower total cost of ownership (TCO) compared to traditional on-premise or private cloud solutions.
SAP Public Cloud is ideal for small to medium-sized businesses (SMBs) or organizations that seek a scalable, flexible, and efficient ERP system with minimal complexity.
Not every SAP S/4HANA is SaaS. For example, SAP HANA Cloud is DBaaS, whereas SAP S/4HANA Cloud is SaaS.
What is SAP S/4HANA Private Cloud Edition?
SAP S/4HANA private cloud is a cloud-based deployment model from SAP. Instead of the multi-tenant architecture, the S/4HANA private cloud, as the name suggests, provides a dedicated, single-tenant ERP environment.
It offers extensive customization and integration capabilities similar to on-premise deployments while leveraging cloud infrastructure managed by SAP.
Comparison Between the SAP S/4HANA Public and Private Cloud Edition
| Features | SAP S/4HANA Public Edition | SAP S/4HANA Private Edition |
|---|---|---|
| Deployment Model | Multi-tenant, shared environment with standard configurations. | Single-tenant, dedicated environment with full control over infrastructure. |
| Deployment Speed | Faster due to pre-configured processes and standardized setup | Slower due to custom configurations and integration requirements |
| Infrastructure Control | No access to underlying infrastructure layers | Greater control over VMs, network, and storage |
| Customization Capabilities | Limited to standard configurations and minor in-app extensibility | Extensive customizations (ABAP code, custom modules, UI changes) |
| Integration Capabilities | Pre-defined SAP integration scenarios and third parties. | Supports complex SAP and non-SAP integrations. |
| Update and Upgrade Management | Quarterly automatic updates managed by SAP | Flexible, customer-controlled upgrades |
| Data Model Modification | Limited to creating custom fields via in-app tools. Standard table modifications are not supported, which can limit data structuring for specific business processes. | Full flexibility to modify SAP standard tables and data models, create custom fields, and even modify data structures. |
| DevOps Pipeline | Follows SAP’s standard DevOps and continuous integration (CI) tools. Custom deployment pipelines are not allowed, and changes are restricted to configuration-based deployments. | Custom DevOps pipelines can be set up, enabling custom code deployments, testing environments, and dedicated QA processes. |
| Analytics and Reporting | Integration with SAP Analytics Cloud is supported, but customization is limited to in-app reports. Advanced reporting using custom code or data extraction is not possible. | Allows integration with SAP BW, SAP Analytics Cloud, and third-party analytics tools. Full access to customized reports using CDS Views, ABAP, and other data extraction tools. |
| Performance | Performance may vary due to shared infrastructure | Consistent performance with dedicated resources |
| Scalability | Automatic scalability but can be impacted by multi-tenant load | Scalable but may require manual provisioning and approval |
| Security and Compliance | Standard security policies, limited configuration options | Enhanced security controls support advanced compliance needs |
| Licensing and Cost | Lower cost with standardized pricing and shared resources | Higher cost due to dedicated resources and flexibility |
| Extensibility | Limited extensibility, focus on “keep the core clean” principle | Deep extensibility with custom development and integrations |
| Industry-Specific Requirements | Best for standardized industries like retail, services, public sector | Suitable for complex industries like manufacturing, automotive |
| Pain Points | Limited flexibility, compatibility with enforced updates | Complexity, higher TCO, longer deployment time |
| Target Audience | Small-to-medium businesses prefer rapid deployment | Large enterprises needing complex ERP landscapes |
