Cloud Databases
Subscriber-centric data architecture for telecoms


Network Function Virtualization (NFV) and the planned 5G service-based architecture will fundamentally transform network (NF) functionality. The network functions will implement more and more cloud native principles. For this purpose, off-line stateless functions are split off, while internal information about subscriber-specific session and registration states are outsourced to an external, cloud-based database. The network functions achieve much better scalability, elasticity and availability, and the network architecture is considerably simplified.

Choosing an appropriate cloud database becomes essential to customer satisfaction as it becomes the foundation of all network capabilities and can significantly improve availability and operational costs.

SilverEngine, with its longstanding experience, helps telecom companies to select the most appropriate databases, define implementation methods, and implement and deploy these technical solutions as well as cloud database and NVF providers to understand and comply with the requirements of an NSP-grade cloud database for the telecommunication industry.

Our approach for cloud databases

To realize a viable cloud database which supports stateless and cloud-native network capabilities, a comprehensive analysis of the current system architecture, data structures, and data distribution is recommended.

On the basis of the actual analysis, the target system architecture is defined and possible transformation and migration scenarios are evaluated. For the effective implementation of a cloud data architecture, a detailed step-by-step plan is defined together with the customer. During the implementation phase, SilverEngine also supports its customers and the change process.


  • As-is analysis

    Analyze current architecture (applications and databases), data structure, data flow and redundancies as well as evaluate and prioritize uses case

  • Definition of target architecture

    Define integrated target system architecture, develop requirements list for cloud database and support selection process related to possible database solutions

  • Design of transformation

    Evaluate different approaches for transformation and migration as well as develop a staged implementation plan

  • Implementation

    Data migraton, project management and provision of technical support

Your benefits

  • Improved customer service and thus, better customer experience

  • Higher speed-to-market of new services and applications

  • Increased customer loyalty

  • Improved performance an scalability as well as reduced OPEX

Our capabilities

SilverEngine is one of the pioneers in implementing Unified Data Repositories (Subscriber Data Management - One-NDS). Right from the beginning, SilverEngine’s team has defined the requirements for cloud databases based on the planned 5G service-based architecture. SilverEngine has in-depth knowledge of the latest technologies and many years of experience in the implementation of scalable, highly available and above all robust data center architectures.

Essential is also SilverEngine’s outstanding know-how regarding concept, architecture and functional and non-functional requirements as defined in the white paper “A Network Data Layer (NDL) Concept for the Telco Industry” issued by ngmn – next generation mobile networks.
