Component’s Interactions. The Service Graph Editor component interacts with the following component. Interacting Component Description Service Graph Repository Repository that exposes an API that manages the application graphs and their constraints.
Component’s Interactions. The Policy Editor component interacts with the following component.
Component’s Interactions. The Deployment Manager component interacts with the following components.
Component’s Interactions. The Deployment Manager component interacts with the following component. Interacting Component Description Pre-Deployment Constraint Solver Connects to the Deployment Manager to receive and solve the hard and soft constraints introduced from the applications and their components Orchestration Lifecycle Manager Receives from the Deployment Manager all the necessary data and settings for its deployment. The data are provided by the Orchestrator Repository.
Component’s Interactions. The orchestration Lifecycle Manager component interacts with the following components. Interacting Component Description Deployment Manager Deployment manager triggers a new instance of the Orchestration Loop and receives all the necessary information in order to start the deployment and maintenance procedure. Orchestrator Repository It saves and fetches the current and previous orchestration loop states respectively. Resource and Application-level Monitoring It provides to the Orchestrator the necessary resource and application level monitoring metrics. Resource Manager It supplies information about the resources that are currently available/allocated on each node. This is crucial for determining the appropriate node for scheduling.
Component’s Interactions. The resource manager interacts mainly with two other RAINBOW components: Interacting Component Description Resource and application-level monitoring It supplies current resource usage data. Orchestration Lifecycle Manager It contains the scheduler, which is responsible for selecting the appropriate nodes for deploying the workload, based on the available and allocated resources reported by the resource manager.
Component’s Interactions. The Resource and Application-level Monitoring component interacts with the following component of the RAINBOW platform. Interacting Component Description Orchestration Lifecycle Manager It provides monitoring configuration (e.g., monitoring metrics, metrics collection periodicity) and knowledge about the topology of the underlying infrastructure and application services. The monitoring data is published to the High-Performance Queue component and can be accessed by other components of the RAINBOW platform (e.g., Analytics Engine, Storage Manager).
Component’s Interactions. The mesh routing protocol stack is in essence a peer-to-peer component. As such it can communicate with any node in the fog deployment in order to perform neighbour- identification, overlay establishment, cluster-head election and path discovery. It should be clarified that the communication of each node with the centralized orchestration entity is achieved through the cluster-head.
Component’s Interactions. The Multi-domain sidecar proxy component interacts with the following component of the RAINBOW platform. Interacting Component Description Orchestration Lifecycle Manager It can propagate specific events that cannot be handled within the vicinity of the agent.
Component’s Interactions. The Security Enablers component interacts with the following component of the RAINBOW platform. Interacting Component Description Policy Editor Policy Editor compiles the set of attestation policies, including configuration properties to be verified during deployment and operation of Interacting Component Description cloud-native components. These will be deployed and enforced through the Deployment Manage. Deployment Manager It deploys and enforces the attestation policies to be verified by the RAINBOW security and trust enablers.
