What is SAP On Premise?
When SAP started its ERP services, it has to go physically to the place/company i.e. on premise/location where it wanted to install its software.
This software is the one, which is installed and runs on the premise(the work area/building) of that company. All the ERP solutions provided by SAP, i.e. SAP CRM, SAP Suite, SAP HCM, etc., are on premise solutions.
Advantages of SAP On Premise:
- Pre-configured hardware
- Preinstalled software
- Solution validation by SAP and partner
- Reduced Risk
- Increased flexibility and control
Disadvantages of SAP On Premise:
- High Initial Investment
- Hardware Management Required
- Software Update Required

What to choose between On Premise and Cloud?
This is a very important question regarding service selection. SAP provides ECC & ERP services in two ways. Both of them have HANA Database. The selection is purely based on the requirement of the customer. In the given table, we will explain possible conditions where these two services are applicable:
| Feature | SAP On Premise | SAP On Cloud |
| Infrastructure | It is installed within the premise. You have to pay for infrastructure installation. | It is a cloud based service. You need to pay for the service as per your use. |
| Support | The support team of the enterprise can handle it. | Total support dependency is on SAP. |
| Upgrade | Every year new upgrades will be required. | The cloud is upgraded by SAP itself. |
| Functional | Full ERP solution is available | Limited ERP solution is available |
| Investment | Hardware, Software and support team | Payment as per service and time |
You can even choose a hybrid version where you can have functionality and the advantage of both on-premise and on-cloud. For more information, click here.
