gs-linkgw

This repository includes open sources of gs-link for connection between single cluster or multiple clusters and cooperation between them in gedge-platform. The cooperation means collaboration between data points and K8S cluster including offloading and migration. Also, gs-link provides the link between K8S clusters for cooperation.

The gs-linkgw opensource

This repository includes test code for migration from opensource with some variables which are fixed format to execute with in single K8S. https://github.com/qzysw123456/kubernetes-pod-migration

Also, this repository provides the controller for migration amoong K8S clusters based on opensource. https://github.com/schrej/podmigration-operator https://github.com/SSU-DCN/podmigration-operator

The structure of gs-linkgw

This figure shows the structure of gs-linkgw

The gs-linkgw consists of three modules as follows.

• GS-Link Collaborative Management Module: Provides multi-cluster connection management, multi-cluster offloading and service movement management, multi-cluster shared storage management and multi-cluster resource management functions.
• GS-Link collaboration service linked operation module: Provides core-edge, edge-edge interworking function and shared storage operation function for data collaboration processing
• GS-Link Collaboration Support Offloading and Service Mobility Module: Provides dynamic deployment of services and service mobility to support vertical/horizontal collaboration by jointly utilizing computing resources of the core cloud and cloud edges

The module presented above is a function-oriented module and performs the following roles to provide services for actual GS-Link.

• GS-Link's collaboration management module serves as an API to support service collaboration functions and manages and monitors the system for collaboration.
• GS-Link collaboration service linkage operation module plays a role of data collaboration through connection between K8S clusters and shared storage between clusters
• GS-Link collaboration support offloading and movement module performs real-time high-speed movement and offloading between K8S clusters
