Appmixer consists of multiple technologies that interact with each other:
Appmixer Engine: the main system that manages flows, orchestrates components within running flows and provides a HTTP REST API interface to access all the entities within Appmixer. The Appmixer engine is implemented in NodeJS and can run on a single node or in cluster. The engine is horizontally scalable providing high availability and fault tolerance capabilities.
Appmixer Backoffice: the admin panel UI providing overview of all the flows and users in Appmixer together with configuration.
Appmixer CLI: the command line tool that is mainly used to manage custom connectors (upload, delete, ...).
Supporting Technologies: RabbitMQ message broker, MongoDB NoSQL database, ElasticSearch search engine, Logstash collector of logs and Redis key-value store. All the supporting technologies can also run either on a single node or in cluster.
