Edge applications: Just right consistency

CRDTs are distributed data types that make eventual consistency of a distributed object possible and non ad-hoc. Geo-distributed systems are spread across multiple data centers at different geographic locations to ensure availability and performance despite network partitions. These systems must accept updates at any replica and propagate these updates asynchronously to every other replica. Conflict-Free Replicated Data Types (CRDTs) ensures eventual consistency in the replicas despite asynchronous delivery of updates. Extending this idea to fog computing servers where connection reliability is low, eventual consistency amongst the servers is required. We configure Kubernetes, an open-source container orchestration system used for automating deployment, scaling, and management of containerized applications, and use it for cluster deployment of CRDT based low resource intensive AntidoteDB can be used for deployment on fog servers to ensure eventual consistency amongst these servers. We have developed an automated benchmarking tool for benchmarking edge computing applications.
