EdgePersist

A Framework for Enabling Edge Storage in IoT and Smart Device Networks

EdgePersist

EdgePersist is a package of components that enable edge storage for IoT and smart device edge networks. It consist of three main components:

  • Edge Storage Component: the core component that provides the edge storage capabilities based on MinIO, K3s and Prometheus.
  • Edge Localized Docker Registry: the localized docker registry that uses the edge storage component as a back end for real-time and proactive docker image migration and replication.
  • Edge Registry Sync Daemon: a daemon process that syncs the localized registry to one or more remote ones based on a Kafka message bus.

Features

EdgePersist aims to provide a reliable, fast, stable and secure shared storage engine, accessible by all devices and users in an edge/cloud continuum. Furthermore, it needs to be extremely lightweight since it is created for edge devices with extremely limited resources, like Raspberry Pies or other micro-computer devices.

Inherently decentralized and highly scalable P2P solution

An open-source framework, called MinIO is utilized. MinIO is an inherently decentralized and highly scalable P2P solution, allowing us to deploy it freely on usable nodes. It is designed to be cloud native and can run as lightweight containers managed by external orchestration services such as Kubernetes.

Object storage over block storage

MinIO uses object storage over block storage so it is in fact a combination of the two systems, preserving the lightweight distributed nature of block storage while providing the plethora of metadata and easy usage of the object storage.

Web-based GUI and an AWS S3 compatible API library

MinIO offers a web-based GUI and an AWS S3 compatible API library for easy accessibility and integration. This allows users to interact with MinIO using familiar S3 API commands and provides a user-friendly interface for managing and accessing stored data.

Datashim Integration

The Kubernetes Dataset Lifecycle Framework provided by IBM’s Datashim is employed on top of MinIO, allowing the edge storage component to be used as a file system folder, which is useful for applications that we cannot or do not want to integrate with the Restful API of MinIO.

Localized Docker Registry support

A Localized Docker Registry is provided using EdgePersist as its file storage backend, in order to move application images closer to the edge and limit network traffic and image download times.

Registry sync daemon support

A daemon process that syncs the localized registry to one or more remote ones based on a Kafka message bus. It aids in the pre-loading and replication of application images from remote registries or filestorage systems into the Localized Docker Registry.

Semi-automated deployment and off-loading

A set of bash and yaml scripts have been developed that handle all the configuration, installation and deployment processes that need to be contacted before and after the MinIO workers are deployed. This ensures that scaling can be performed seamlessly on each cluster, regardless of the underlying physical machines that act as nodes.

Harmonization of IoT network diversity

K3s is used as an orchestrator which is compatible with most devices that run windows or unix based operating systems. This enables to create highly configurable generalized deployment scripts that handle the deployment, configuration, un-deployment and re-deployment of the storage workers. In addition, Dataset Lifecycle Framework provides a uniform way of accessing the data, using the local file system of each device, eliminating the need of customized solutions for each new device.
