Case Study
Maincubes One

B2B customer self-service and customer portal for data centre.

Case Study 
Maincubes One

The Europe-wide data centre operator Maincubes One offers its customers the use of their infrastructure in its own high-security data centres. The operator's core services include the provision of secure buildings, connection to a stable and redundant energy supply, and the provision of high-performance Internet connections for the operation of customer infrastructures (Infrastructure as a Service). The provision of infrastructure is therefore the core service of the data centres and is relevant for billing customers.

Initial situation and Challenge

With the increasing number of new customers, the data centre operator Maincubes One was faced with the challenge of avoiding manual tasks for the preparation of the numerous billing data. At the same time, customers expressed the desire to always have access to up-to-date data regarding the performance of their own infrastructure.


Based on the challenges, a hybrid portal solution based on Intrexx was created, which enables a connection to the power supply and to the internet supply via thousands of sensors. Relevant documents (contracts, invoices, etc.) are provided by the operator of the data centre via one of the portals. In addition, via an extranet, performance data for power and Internet usage is made available to customers in near real time based on sensor technology. The data centre’s customers also have the option of granting authorisations for third-party access to the data centre.


  • Saving costs and resources by avoiding manual effort and using different software solutions for billing services.
  • Consolidation of data from different sources.
  • Transparency towards customers and creation of self-services.


  • Sensors, IoT, Industry 4.0.
  • Process digitisation.
  • Extranet.
  • customer self-service.
  • Data Integration.

Applications based on Intrexx

The hybrid portals were implemented on the basis of the low-code platform Intrexx. Intrexx offers up to five times faster development of business applications than is possible with conventional programming techniques. Citro is a certified Intrexx partner. If Intrexx, then with us.
