Cloud & Network Synergy

Cloud Native Core Network enables telecom networks to better serve vertical industries and help industry customers accelerate digital transformation. CNCF defines cloud native technology as it helps the company and organization build and run elastic applications in new dynamic environments such as public cloud, private cloud and hybrid cloud. The representative technologies of Cloud Native include microservices, stateless design, service grids, containerization, immutable infrastructure and declarative APIs. These technologies can build a loose coupling system with good fault tolerance and easy management and observation. With reliable automation methods, cloud native technologies enable developers to easily change the system frequently and predictably. 

Based on cloud-based technologies, software applications can not only fully enjoy the efficient and continuous service capability of the "cloud," but also rapidly and efficiently respond to changing customer requirements. In the face of the changing and differentiated requirements of various industries, the 5G slicing solution needs to be deployed quickly on demand, build cloud native-based 5G core network by making good use of cloud native ideas and models,which will inevitably serve thousands of 5G industry connection requirements for digital transformation. 

The Cloud Native Core Network is required to meet the requirements of the Cloud Native Application Micro-Service Component Selection, Gray Upgrade, and Flexible Deployment, irrelevant to infrastructure. Cloud Native is used as the next-generation virtualized core network architecture. The cloud-native core network application has the following four features:

1. Microservice decoupling: Applications are decoupled into a group of independent microservices, which can be deployed, upgraded, and scaled independently. 

2. Stateless: Stateless design is used for service processing, providing an independent state storage layer. 

3. Automation: Cloud-native applications should be highly automated at all stages, including blueprint design, resources scheduling and orchestration, life cycle management, status monitoring, and policy control and update. 

4. Lightweight virtualization: The container technology can be used to deploy application components in the cloud native application architecture design. This can improve resources usage and achieve fast service delivery and agile application maintenance. In actual deployment, cloud native applications are decoupled from underlying virtualization technologies. They can be deployed in an environment where containers and VMs are combined. 

5. DevOps: Programmability based on telecom network functions is critical to service innovation and ecosystem enrichment. Compared with the traditional network architecture, Cloud Native has the advantages of high efficiency, flexibility, and exposure. It can meet the requirements of 5G software architecture, and has become the best choice for operators to build or replace core network equipment. 

ZTE Cloud Native 5G Network Architecture: Based on Cloud Native Cloud Native architecture, ZTE core network employs lightweight virtualization technology to subdivide network functions into atomic stateless micro-service components. DevOps develops integrated O&M model to meet continuous and rapid service delivery, and implements on-demand slice customization for 5G scenarios through flexible invocation and combination of components. Continuous application integration is continuously released to respond to market requirements. Gray release reduces upgrade risks and improves user experience. Stateless design, faster scaling, and higher reliability .
