Cloud Native Architecture

Cloud Native Accelerate the Digital Transformation of Communications Industry


Cloud native technologies empower organizations to build and run scalable applications in modern, dynamic environments such as public, private, and hybrid clouds. Containers, service meshes, microservices, immutable infrastructure, and declarative APIs exemplify this approach.These techniques enable loosely coupled systems that are resilient, manageable, and observable. Combined with robust automation, they allow engineers to make high-impact changes frequently and predictably with minimal toil. With cloud-based technologies, you can better leverage your business to “cloud” or migrate it to the cloud platform to enjoy efficient and continuous service capabilities of the “cloud”. When you face the deployment of various cloud-based and 5G on-demand slicing solutions, using Cloud Native thinking and models to build a cloud-based 5G core network is bound to accelerate the digital transformation of the entire communications industry.

Cloud Native Core Network Features


The core network architecture design requirements can meet the flexible deployment of network elements, open service capabilities, and 5G network slicing. Cloud Native is the next generation virtualized core network architecture. The cloud-based core network applications have the following four features:
1. Microservice: Applications are constituted in the granularity of stateless microservices.
2. Automation: Cloud Native applications should be highly automated at all stages, including blueprint design, resource scheduling and orchestration, lifecycle management, status monitoring, and policy control updates.
3. Lightweight virtualization: In the Cloud Native application architecture design, container technology can be used to deploy application components. This improves resource utilization and enables fast service delivery and agile application maintenance. In actual deployment, Cloud Native applications are decoupled from underlying virtualization technologies. They can be deployed in a mixed environment of containers and VMs.
4. DevOps: Programmability based on telecom network capabilities is critical to service innovation and ecosystem richness. Cloud Native is more efficient, flexible, and open than traditional network architectures. It can meet the needs of 5G software architecture and has become the best choice for operators to build or replace the core network equipment.

ZTE Cloud Native 5G Core Architecture


Based on the Cloud Native architecture, ZTE Common Core uses lightweight virtualization technologies to divide network functions in details into atomic stateless micro-service components. The DevOps development operation and maintenance integration model satisfies the continuous and rapid delivery of services and achieve scenario-oriented slicing on-demand customization of 5G through flexible invocation and integration of components. The continuous integration and release of applications responds to the market demands more rapidly. Grayscale release reduces upgrade disks and promotes user experiences. ZTE Common Core provides stateless designs for faster scaling and higher reliability.
