What is SAP S/4HANA?
SAP S/4HANA (SAP Business Suite 4 HANA) is SAP's next-generation Enterprise Resource Planning (ERP) software designed to run exclusively on SAP HANA, an in-memory database. Launched in 2015, S/4HANA offers real-time analytics, streamlined processes, and advanced user experiences through SAP Fiori. It marks a significant shift from SAP's previous ECC (ERP Central Component) system, representing a modern, agile, and data-driven approach to business management.
Key Versions of SAP S/4HANA
SAP S/4HANA is available in two main deployment options :
1. On-Premise
Installed and maintained on a company's own servers.
Offers maximum customization and control over the system.
Typically suited for larger enterprises with complex business needs and IT infrastructure.
Annual updates are released by SAP.
2. Cloud
Hosted on SAP's cloud infrastructure or other cloud platforms (AWS, Azure, Google Cloud).
Available in three variants:
SAP S/4HANA Cloud Essentials: A public cloud offering with standardized processes and quick deployment.
SAP S/4HANA Cloud Extended Edition (EX): A semi-public cloud option offering more customization and flexibility than Essentials.
SAP S/4HANA Private Cloud: Provides similar flexibility to the on-premise version while being managed in a private cloud setup.
Frequent updates, typically quarterly.
3. Hybrid
Combines on-premise and cloud solutions, enabling businesses to maintain sensitive operations on-premise while leveraging the cloud for scalability and innovation.
