- Federation Scheduler (Included in Release-5): As a “Global Scheduler”, responsible for application QoS oriented global scheduling in accordance to the placement policies. Essentially, it refers to a decision-making capability that can decide how workloads should be spread across different clusters similar to how a human operator would. It maintains the resource utilization information for all the MEC edge cloud sites. Cloud federation functionality in our blueprint is enabled using open source Karmada project. Karmada (Kubernetes Armada) is a Kubernetes management system that enables cloud-native applications to run across multiple Kubernetes clusters and clouds with no changes to the underlying applications. By speaking Kubernetes-native APIs and providing advanced scheduling capabilities, Karmada truly enables multi-cloud Kubernetes environment. It aims to provide turnkey automation for multi-cluster application management in multi-cloud and hybrid cloud scenarios with key features such as centralized multi-cloud management, high availability, failure recovery, and traffic scheduling. The following is a architecture diagram for Karmada. More details related to Karmada project can be found here.
- EdgeMesh (Included in Release-5): Provides support for service mesh capabilities for the edge clouds in support of microservice communication cross cloud and edges. EdgeMesh provides a simple network solution for the inter-communications between services at edge scenarios (east-west communication). The network topology for edge cloud computing scenario is quite complex. Various Edge nodes are often not interconnected and the direct inter-communication of traffic between applications on these edge nodes is highly desirable requirement for businesses. EdgeMesh addresses these challenges by shielding the complex network topology at the edge applications scenario. The following is a architecture diagram for Karmada. More details related to EdgeMesh project can be found here.
