Requirements for operation in the ems Cloud #
Operation in the ems Cloud requires certain prerequisites to ensure optimal use of the platform. These requirements offer simple and effective use without the need for your own infrastructure.
The ems Cloud is completely browser-based. This means that all users can access the platform via a modern web browser without having to install additional software. This enables seamless integration into different working environments and significantly reduces maintenance costs.
Browser requirements #
To ensure the best performance and security when accessing the ems Cloud, it is necessary to always use the latest version of a supported browser. The following browsers are supported:
- Google Chrome (latest version)
- Mozilla Firefox (latest version)
- Microsoft Edge (latest version)
- Apple Safari (latest version)
Please check your browser regularly for updates to ensure that you are using the best functions and security standards.
Requirements for operation on the customer infrastructure (OnPremise) #

The following list is an example configuration. The exact requirements for the infrastructure are determined by the customer through parameters such as reliability etc.
Infrastructure requirements #
Database server #
The database server contains the central database of the ems system. Special users are also set up on the database server to enable access for the various programs and update systems.
- SQL Server 2016 (or newer)
- Database size approx. 300 MB per year
The Express Edition is available for up to 20 users, after that the Standard Edition is required
Document storage #
The document repository contains the documents that are created as files in the ems system. All documents are integrated by the ems system and the user has no access to the direct data.
- Fileshare under NTFS with access by service users
The storage requirement depends on the use
Websites #
- Windows Server 2019 (or newer)
- IIS (included in Windows Server)
- Storage space for websites approx. 200MB
Depending on the availability requirements, an NLB system should be used to distribute the load.
If external access to the websites via a proxy is not possible, an additional dedicated web server can be placed in the DMZ.
Application server #
- Windows Server 2019 (or newer)
- IIS (included in Windows Server)
- Microsoft .net 4.8 Framework
- Crystal Reports Runtime 13 (provided by SUBRIS)
The application server can optionally be operated on the same server as the websites.
Connections #
- External DNS entry URL and certificate for using ems Web via the Internet
- Access to the e-mail server with authorizations to send e-mails
Obligations and tasks of the customer #
Licensing #
The customer shall ensure the licensing of the servers.
This applies in particular to the Microsoft licenses for Windows Server and the SQL database.
Data security and backup #
The customer decides for himself how the backups are carried out.
Confidentiality #
The data structure and system parameters that are accessible to the customer are subject to confidentiality.
Change on-premise operation / cloud operation #
It is possible to switch between on-premise operation (operation at the customer’s premises) and cloud operation or vice versa at any time.
The following components must be migrated:
- ems database
- ems file storage
