* Machine Learning framework runs experiments on a fraction of live shopping traffic to test performance of different variations of Intellisell config settings. It uses the experiment results to train models to predict the optimal settings and will implement the models in Intellisell to use the ML learned optimized settings during shopping.
* Intellisell - an orchestrator application for all Air Shopping systems. It implements many processing flows (high level services) by making calls to several data sources (low level services).
* Intellisell Cache - an advanced, home-grown caching solution, optimized for use cases required by Intellisell. It stores each priced itinerary option that has been returned by shopping data sources. Such options can be later on independently fetched by subsequent shopping requests and combined into new shopping offers. It can work with almost any of the multitude of shopping data sources.
