In her October 12, 2018 presentation at the Linux Foundation’s Open Source Networking Days in Shanghai, Wenjing Chu described its Kubernetes-and-Docker baseline and design goals for security, observability, validation, and automated deployment. The talk and the project documentation are historical; the sources cited here do not establish whether Clover is maintained or suitable for new deployments today.
What is Clover?
Chu’s slide deck defines Clover as “a framework stack to develop network services as cloud native micro-service applications that can be developed, deployed and operated with high degree of automation.” In this context, a network service could be a software network function, including an application or a management, control, or data plane function. The talk identified Kubernetes and Docker containers as Clover’s baseline. Wenjing Chu’s presentation

That framing made Clover a framework for composing and operating network functions as software services, rather than a single networking application or a hardware device. Its scope included the operational work around a service as well as the service itself.

What did the 2018 talk say cloud native meant for networking?
The presentation organized Clover’s aims around several challenges that arise when network functions are built and run as microservices:
#1 Best Overall
- Segmentation, traffic control, and security: applying service-mesh concepts to control communication among service components and provide unified security.
- Visibility and operations: tracing, monitoring, and visibility intended to help debug services and operate them.
- Validation: automating checks of network-service characteristics.
- Continuous deployment: automating service rollout and related operations.
- Flexible deployment: supporting deployment across diverse environments.
These are design areas presented in 2018, not proof that every capability was complete, production-ready, or remains supported. The deck also discussed Clovisor, a network-tracing effort that used Clover with IOVisor/eBPF. Its discussion of Clovisor in relation to Istio reflected the talk’s historical framing; it should not be read as a current performance comparison or recommendation. Presentation slides
Who presented the talk, and where?
The Linux Foundation event agenda lists the session as “OPNFV Clover: Delivering Cloud Native Network Services” at Open Source Networking Days in Shanghai on October 12, 2018. The agenda identifies Chu as Senior Director of Open Source and Research at Huawei. The slide deck identifies her as Senior Director of Open Source & Research at Futurewei Technologies, Inc.; those are the affiliations given by the two sources, respectively. The event page describes the gathering as bringing developers, users, and communities together around open networking projects. Linux Foundation event agenda

What do the old Clover guides cover?
Legacy Clover documentation describes additional project material and components, including a sample service, an Istio 1.0 integration, clover-collector, visibility and analytics, cloverctl, and Clovisor. The user guide discusses the Hunter release. These documents help show the historical breadth of the project, but they do not establish compatibility with present-day Kubernetes or Istio versions, current support, or production readiness.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What should a modern reader take from the presentation?
Read Clover as a historical approach to treating network functions as cloud-native applications, with operational automation and visibility included in the design problem. The 2018 talk is useful for understanding that ambition and the components it discussed; it is not current deployment guidance. The reviewed presentation and legacy guides do not settle whether Clover is maintained today or whether its dependencies remain compatible in 2026.
If evaluating Clover or comparing it with another platform, check these points against current project documentation and support information:
