 # Architecture
 
-StarRocks has a simple architecture. The entire system consists of only two types of components; frontends and backends. The frontend nodes are called **FE**s. There are two types of backend nodes, **BE**s, and **CN**s (Compute Nodes). BEs are deployed when local storage for data is used, and CNs are deployed when data is stored on object storage or HDFS. StarRocks does not rely on any external components, simplifying deployment and maintenance. Nodes can be horizontally scaled without service downtime. In addition, StarRocks has a replica mechanism for metadata and service data, which increases data reliability and efficiently prevents single points of failure (SPOFs).
