New technical solutions

In order to underline the innovative approach of the Wirtschafts-Service-Portal.NRW (WSP.NRW), we continuously focus on the use of new technologies as well as creative and at the same time pragmatic solutions. The WSP.NRW is therefore in a continuous agile development.

The following pages contain information on architecture, new technical solutions and the connection of new basic components.

Microservice architecture

Based on a microservice architecture and various open source software solutions, the EfA minimum requirements are met. As a result, application services can be integrated as microservices of the WSP.NRW as well as application services or microservices co-used via the WSP.NRW. In contrast to a monolithic, i.e. self-contained and independent architecture, this approach offers the following advantages:

Flexibility: The effort required to adapt individual components is
less than a monolithic application. There is a higher
technical flexibility.
Scalability: Extensions of the components can be made by connecting
be carried out by interface without further ado.
Failure-proof: Due to the simplified analysis and the encapsulation of the
Components are given a higher reliability.

In addition, an architecture based on microservices is able to flexibly implement new functionalities without having to force a complete new development of the portal. Thanks to this modular system, the WSP.NRW is able to react quickly to new framework conditions and implement them in an agile and demand-oriented manner.

ELSTER company account with mailbox 2.0

Every year, companies have around 200 contacts with different authorities. In order to enable uniform access and a central mailbox, the ELSTER company account was created.

For companies (single companies, partnerships, corporations) and associations, the portal and associated account ‘My Business Account’ has been created, which unifies nationwide communication between companies and institutions. The connection is realized via the ELSTER/NEZO interface. The authentication options offered are:

  • ELSTER certificate file (one-time identification by post)
  • ID card with online ID card function (card reader/ID card app2 for mobile devices)
  • Signature card in conjunction with the ElsterAuthenticator software
  • Security stick in connection with the software ElsterAuthenticator

Registration via ELSTER is also possible for private individuals.

Content and meaning of the ELSTER company account and the mailbox 2.0

With the mailbox 2.0, the ELSTER mailbox is expanded and expanded by other functions, such as the acceptance of messages via the Internet. As a result, documents from the WSP.NRW can be legally delivered to the corresponding mailboxes of citizens and companies.

For applicants, this means that decisions or documents from many procedures are delivered and stored centrally in the respective mailbox.
