Overview of S/4 HANA Public and Private Cloud Editions

It is important for CIOs (Chief Information Officers) to understand the capabilities of the “S/4 HANA” deployment options as they compare their deployment with public and private clouds. S/4 HANA is an ERP (Integrated Business) application based on the in-memory data processing product ‘SAP HANA’, and is a continuation of SAP’s ‘ERP Central Component’ (ECC).

S/4 HANA is available in public and private clouds. In addition to being available in the on-premises version, a hybrid model that combines the cloud and on-premises software is also available. All of these versions incorporate the user interface (UI) of SAP’s application group “SAP Fiori”.  When CIO evaluates whether S/4 HANA will be used in public cloud or private cloud, it is necessary to carefully consider several factors. You must determine the best option to meet your needs in terms of cost, ease of implementation, industry specificity, and data security.

Overview of S / 4 HANA Public Cloud Edition and Private Cloud Edition

The public cloud version of S/4 HANA is Software as a Service (SaaS). This is a multi-tenant version of the software, where all tenants (user companies) share the same cloud. Therefore, it is low in cost and high in efficiency as well as excellent in scalability. In other words, it can be used to upload data for each tenant, turn on and off the required and unnecessary functions, and is general-purpose, cloud-native ERP software that can be used immediately. Preparation is ready in a few weeks.  

SAP will be responsible for the infrastructure management of public cloud version S/4 HANA and regular maintenance of the system. This includes upgrades and patches. SAP also ensures data cybersecurity, governance and compliance.

Difference between Public Cloud And Private Cloud

Public cloud is a cloud service provided to general users among services operated by cloud computing (cloud service). This service is widely offered to a large number of unspecified users such as various companies, organizations, or individuals. You do not have to maintain dedicated hardware, and you can use the server and network system as you need. If you want to use the services of a specific company, it is a form that can be used immediately if you apply online. The public can freely manage data anywhere via the Internet without being aware of where the data is, so that it can be translated as “public”.

Private cloud refers to a form in which companies build their own cloud computing system and provide cloud services to departments and group companies in the company. It can be said that it is not a broad-opened service like the public cloud, but a form of service provision in a narrower range. With private clouds, you can design and manage systems within a company like traditional in-house systems, enabling flexible service design. Also, in terms of security, you can apply your own security policy, so you can operate flexibly after establishing strong security.


Cloud computing is an area of ​​increasing interest in the IT industry.  The reason is that if you can use cloud-based “virtualization” infrastructure effectively, you have the potential to outperform traditional data centers in the areas of performance, scalability, and even security. I can do it. In that sense, it is possible to realize optimal IT service operation by understanding the features of both public cloud and private cloud and linking them while using them in the right place. Operation of both systems in the right place is the key to the success of future IT strategies.
