What is chubby?

First, a simple understanding, and then add:

To solve the consistency problem of hadoop distributed systems, many people have proposed many protocols, including the paxos algorithm (proposed by latex, algorithms need to be learned ),

However, Chubby is not an algorithm or protocol. It is a service and a lock service. The implementation of this service is a distributed file system. Why not use protocol? In addition to implementing consistency, this service can be used more.
