Project Description (what it does, why it is valuable, origin and history) 

What does nEdge-nCloud do? 

nEdge-nCloud is a reliable and efficient multi-cloud distributed storage which enables applications and devices at the edge to store data into one or more clouds. nEdge serves as a storage proxy at the edge to pre-process data for reliability and provide unified storage (over multiple cloud storage destinations) to edge applications. nEdge persists and access data in one or more clouds via nCloud, which is deployed in the clouds. 

Why is nEdge-nCloud valuable? 

Leveraging Cloud Storage with Ease at the Edge 

In edge deployment, IoT devices and applications generate a vast amount of data. nEdge-nCloud enables them to store data in a reliable and efficient storage pool of data across private and public clouds, e.g., for archival and backup. nEdge-nCloud supports utilizing multiple public cloud storage as storage destinations, e.g., AWS and Alibaba Cloud. It transparently manages data storage on behalf of the applications, freeing the applications from complex storage setup and management. nEdge-nCloud currently provides a standard network file interface, SMB, for file storage, and a socket-based client interface for custom application integration. 

Efficient and Configurable Data Reliability 

nEdge-nCloud adopts erasure coding to reduce the storage overhead and hence the cost compared to replication. nEdge-nCloud also provides configurable reliability which can be customized according to application storage requirements. It automatically repairs data to ensure data reliability. 

Origin and History of nEdge-nCloud 

nEdge-nCloud is a distributed storage solution co-developed by CU Coding Ltd. and CUHK ADSLab. Ideas of applying nEdge-nCloud to edge deployments, .e.g, smart factories, have won awards in several competitions, including the EdgeX China challenge 2022 and 5th "Bloom Cup” 5G Application Competition. 

Statement on alignment with Foundation Mission Statement 

nEdge-nCloud aligns with the LF Edge Mission Statement: 

• nEdge-nCloud is neutral to edge and cloud platform vendors, providing a unified cloud storage through standard storage interfaces to edge applications over a diversity of cloud storage. 
• nEdge-nCloud enables edge applications to reliably store data into the cloud in a cost-efficient manner. 
• nEdge-nCloud accelerates edge application development and innovation by offloading cloud-tier data management from applications logic. 

High level assessment of project synergy with existing projects under LF Edge, including how the project compliments/overlaps with existing projects, and potential ways to harmonize over time. Responses may be included both here and/or in accompanying documentation.  

nEdge-nCloud can provide storage to projects that gather and manage the data from heterogeneous IoT devices, such as eKuiper, EdgeX, Fledge. One example would be storing video recordings and images of surveillance cameras from the edge to nEdge-nCloud.
