Edge computing brings cloud services closer to the edge of the network, where data originates, and dramatically reduces the network latency of the cloud. It is a bridge linking clouds and users making the foundation for novel interconnected applications. However, edge computing still faces many challenges like remote configuration, well-defined native applications model, and limited node capacity. It lacks geo-organization and a clear separation of concerns. As such edge computing is hard to be offered as a service for future real-time user-centric applications. This paper presents the dynamic organization of geodistributed edge nodes into micro data-centers to cover any arbitrary area and expand capacity, availability, and reliability. A cloud organization is used as an influence with adaptations for a different environment, and a model for edge applications utilizing these adaptations is presented. It is argued that the presented model can be integrated into existing solutions or used as a base for the development of future systems. Furthermore, a clear separation of concerns is given for the proposed model. With the separation of concerns setup, edge-native applications model, and a unified node organization, we are moving towards the idea of edge computing as a service, like any other utility in cloud computing.INDEX TERMS cloud computing, distributed systems, edge computing, formal specifications, infrastructure as software, platform

“…Thereby the causal length of an element increments on each update that reverses the effect of a previous one. [12] As shown in Fig. 3, the states of a CLSet are a partial function s : E → N, meaning that when e is not in the domain of s, s(e) = 0 (0 is the bottom element of N, i.e.…”

Local-first software aims at both the ability to work offline on local data and the ability to collaborate across multiple devices. CRDTs (conflict-free replicated data types) are abstractions for offline and collaborative work that guarantees strong eventual consistency. RDB (relational database) is a mature and successful computer industry for management of data, and SQLite is an ideal RDB candidate for offline work on locally stored data. CRRs (conflict-free replicated relations) apply CRDTs to RDB data. This paper presents our work in progress that augments SQLite databases with CRR for local-first software. No modification or extra software is needed for existing SQLite applications to continue working with the augmented databases.
