The emergence of 5G network communication, IoT devices, edge computing, and AI has accelerated structural changes within the telecommunications industry, creating new needs and opportunities. To remain competitive, telcos must leverage an operational data layer (ODL) with MongoDB to enhance operational efficiency and provide unique value to customers. An ODL acts as an intermediary between data producers and consumers, centrally integrating and organizing siloed enterprise data. By implementing an ODL with MongoDB, telcos can access a rich document model, boost operational efficiency, and unlock the value of previously siloed enterprise data. This is achieved through capabilities such as flexibility in data structures, speed in development, horizontal and vertical scalability, robust security framework, and modern data platform. Telcos can leverage MongoDB's versatility to cast multiple workloads, store any data type, and adopt a rich query language that executes complex operations. An ODL running in MongoDB Atlas benefits from a multi-cloud strategy, empowering telcos to receive large data volumes and high traffic loads essential for modern applications. By implementing an ODL with MongoDB, telcos can gain operational efficiency, differentiate themselves from competitors, and unlock business opportunities that ultimately enable them to set themselves apart.
