● Microservice architecture: The essence of the SBA is based on the three principles of “self-contained, reusable, and independent management”. The network function, which is designed with the concept of “high cohesion, low coupling”, is divided into a series of small services. Each service focuses on a single business function, running in an independent process. With clear boundaries between services, it uses a lightweight communication mechanism to communicate and cooperate with each other to achieve a complete application. Based on this, operators can flexibly customize the networking according to business needs.
● Self-service: Based on the Microservice architecture, from the aspects such as blueprint design, resource scheduling and orchestration, lifecycle management, application state monitoring, control strategy update, a high degree of automation is achieved and effective linkage between the various links is made to achieve a closed-loop feedback mechanism, which can achieve one-click deployment, full autonomy, and efficient management of services.
● Lightweight virtualization: Compared to virtual machines, container technology, which has the advantages such as rapid scaling-in/out, lightweight, and high performance, is rapidly and widely used in the IT industry. The cloud native application and the underlying virtualization technology are decoupled, and can be deployed in the container technology to achieve resource utilization improvement, fast service delivery, and service agile maintenance. The ZTE 5G Common Core Solution supports both virtual machine-based and container-based deployments.
● Stateless: The 5G Common Core Solution adopts the stateless layered design. User access and session information is stored in the data sharing layer. Each Microservice instance in different locations can obtain the latest state of the user through the data sharing layer. Stateless application designs enable separation of applications from data, enabling rapid network resiliency and failure recovery.
