OpenNESS(Open Network Edge Service Software)

Jul. 2020 - Now

OpenNESS is an open source edge application management system based on Kubernetes that enables service providers and enterprises to build, deploy and operate their own edge applications on the edge of any network, enabling easy migration of apps running on the Telco/Public Cloud to the edge.

Jul. 2020 - Aug. 2020

The development of unit tests for part of the core microservice components of OpenNESS, increased the code unit test coverage from about 50% to 100%, the development language is Golang.

  1. Fix a bug introduced by project members via go.mod during development.
  2. The was introduced by me to cover code branches which the test framework could not test under the normal situation.
Sep. 2020 - Nov. 2020

Investigate the application of blockchain and TCF(Trusted Compute Service) projects in OpenNESS. The main work is the Avalon and Fabric ramp-up, which are the sub-project of Hyperledger, and investigation of the open source project Intel K8s Device Plugin and K8s Add-on NFD(Node Feature Discovery) which can support the deployment of Avalon in OpenNESS.

The general idea behind this application is that Avalon1 and Fabric2 which both are distributed computing platforms will be deployed by OpenNESS to show OpenNESS's ability to manage edge computing applications in blockchain and trusted computing scenarios. The blockchain scheme adopts Fabric and Avalon will be used to connect Fabric to do the off-chain computation. Meanwhile, TEE mode is adopted in the Avalon platform to provide trusted compute. TEE uses Intel SGX(Software Guard Extensions) instruction set Extensions and supporting Software, including SGX PSW(Platform Software), Intel K8S SGX Device Plugin3, NFD4 and custom NFD SGX Extension.

During investigation:

  1. I read the official documentation of Fabric and Avalon projects, understood the overall architecture of Fabric and Avalon, walk through the code of Avalon according to the business logic process, clarify myself about how the data is uploaded to blockchain and sent to Avalon for off-chain trusted computing.
  2. I setup a complete set of hardware and software verification environment by deploying a Fabric cluster, and a Avalon platform base Intel SGX hardware, test and verify the whole process of trusted compute.
  3. I studied the official documentation of Intel SGX to understand the concept of SGX, and make knowledge reserve for the correct use of Intel K8S Device Plugin and NFD.
  4. I read Intel K8S Device Plugin SGX related part of the source code, as well as the source code of NFD, setup a test environment to figure out how to use both in order to enable SGX on OpenNESS.
  5. Two technical slides, about Avalon and SGX NFD , are exported, as well as several technical specification documents.
Nov. 2020 - now

Participate in the integration development of EMCO (Edge Multi-Cluster Orchestrator) and OpenNESS to ensure the delivery of tasks at a critical time-point. EMCO is a software framework that provides multi-cluster cloud native application deployment capabilities, it is integrated into OpenNESS to enhance its edge deployment capabilities.

Job content:

  1. I complete the ramp-up of EMCO in several days, take over the existing work, clarify the development tasks, cooperate with foreign developers of EMCO project, and complete the development of Ansible script of OpenNESS automation integration tool.
  2. I coordinate with the integration developers of the other modules (Harbor and Smart City) involved in the EMCO integration effort to ensure that the task is progressing smoothly.
  3. I complete relevant automation scripts and output internal test manual documents, and assist the QA for validation.
  4. I resolve bugs reported by QA and other teams using this feature.
