Five Questions to Start With
1. What is FogBrain?
FogBrain is the core of a declarative continuous reasoning engine that makes informed management decisions for next-gen multiservice applications over Cloud-IoT infrastructures (e.g. Fog computing, Osmotic computing).
2. What is
Declarative Programming is a non-imperative style of programming in which programs describe their desired results without explicitly listing commands or steps that must be performed.
3. How does
FogBrain exploit Declarative Programming?
FogBrain is written in Prolog, a declarative logic programming language. Prolog programs consist of logical statements, and they execute by searching for proofs of (new) statements. Being declarative, FogBrain is only 125 single lines of code.
4. What is
Continuous reasoning is the application of automated formal reasoning to solve real large-scale problems continuously and incrementally, only focussing on "what has changed last" and supporting the CI/CD software release pipeline.
5. How does
FogBrain exploit Continuous Reasoning?
FogBrain extends the concept of continuous reasoning to support the management of multiservice applications, by reducing the size of the considered management problem instance only to application services in need for attention.
