# Appmixer Architecture ## High-Level Architecture Appmixer consists of multiple technologies that interact with each other: ![Appmixer High-Level Architecture](/files/-M8yPT_rKsRd5uzmFLon) * **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 UI SDK**: the JavaScript HTML 5 SDK that allows to seamlessly embed any of the Appmixer UI widgets (including the drag\&drop flow designer) to any 3rd party web page. The SDK communicates with the engine via REST API. * **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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
