The Overall Exponea architecture is inspired by Lambda architecture. For data ingestion we use an asynchronous API with basic input validation. All such events are put into Kafka for further data processing. We use several data storages for specific use cases such as MongoDB (primary copy of most of our data), Redis (cache, fast access, unstructured), MapR (long term archival, data science) and RabbitMQ (campaign workers). For several use cases we provide real time analysis API that triggers computation or data retrieval from our proprietary in-memory analytics engine.

Our cloud solution is deployed on bare metal in Hetzner (DE) datacenter. For several clients we also have private instances, deployed on bare metal, AWS and GoogleCloud. We also use AWS for development environment. At this moment, we are opening markets in Germany and we will deploy our solution there in response to strongneed for data protection.
