CHALLENGE
Building a technical foundation
A major Danish energy and telecommunications company aimed to enhance its service and network abstraction layers to support a digital transformation initiative.
The organization required the design and development of new capabilities using a Quarkus-based microservices stack.
Challenges included integrating these new services with existing systems, ensuring seamless collaboration between business and IT stakeholders, and establishing a foundation for continuous integration and deployment.
SOLUTION
Sustainable & scalable architecture
7N assembled a team with expertise across system development, IT architecture, network design, project management, and scrum.
The team was tasked to deliver a stable technical foundation while building internal capabilities for long-term ownership. Key tasks included:
Design and implementation of a scalable Quarkus-based microservices architecture
Continuous integration and system stabilization, including deployment pipelines, pre-validation APIs, and legacy system migration
Team enablement and knowledge transfer to build an internal team that could take ownership of the solution to ensure long-term sustainability
IMPACT
Lasting impact
The team delivered a lasting impact on the organization by elevating key processes and enabling sustainable change:
Successful implementation
Enhanced the client’s service and network abstraction layers, supporting their broader digital transformation journey
Robust foundation
Established integration and support processes, developed internal tooling, and introduced system dashboards
Enabled internal ownership
Facilitated knowledge transfer and team structure initiatives, ensuring the internal team was equipped to manage the IT stack independently
The team worked homogeneously and with clear interfaces, building solid domain knowledge on encryption systems, network provisioning via Cisco NSO and Netbox, TV provisioning via headends, and provisioning of 3rd party VASs.
They managed all relevant processes related to the task with a proactively and solution-oriented approach, which gave the client predictability and a valid basis for estimating tasks. As the client comments:
