With the growing adoption of the Internet of Things (IoT), connected devices have penetrated every aspect of our life, from health and fitness, home automation, automotive and logistics, to smart cities and industrial IoT. Thus, it is only reasonable that IoT, connected devices, and automation would find its application in…

One technology used by many partners in the LightKone project is Erlang and its standard library OTP, because of its excellent properties when it comes to developing distributed systems all the way down to the light edge. Even though Erlang/OTP has built-in distribution mechanics, those doesn’t always scale to the…

Modern enterprises are realizing that their data is pure gold, but like the gold buried deep in the earth, data is not worth much if it cannot be accessed. Unlike gold, where scarcity increases value, quantity and completeness make data more valuable. …

Despite advancements in connectivity for user devices by service providers, mobile devices will remain subject to frequent periods of disconnection by their very nature. In order for the user to be able to interact with an application during periods of disconnection, the application must store its data on the device…

Data replication is a key technique for building highly available (distributed) systems. Unfortunately, as stated in the CAP theorem, in systems that are prone to network partitions (any distributed system), it is impossible to provide at the same time strong consistency (everybody sees the same updates in the same order)…

The cloud was about server-based communication and content delivery. But, as Peter van Roy put in his recent post, “the edge is becoming the centre”. Edge computing promises fast response, high availability, and keeping private data where it belongs, in the users’ hands. …

The “edge” of the Internet consists of the numerous heterogeneous, loosely coupled nodes situated at the logical extreme of the Internet. The edge is increasing in relevance with respect to data centers. The current situation, in which data centers are effectively in control of the Internet, is becoming unstable. The…

Both distributed aggregation and replication for high availability (yes, I am thinking of CRDTs) are techniques that can help tackle geo-replication, offline operation and edge/fog computing. Distributed aggregation often shares many properties in common with CRDT style convergent replication, but they are not the same concept. …
