Google Chubby And Distributed Systems

Chubby is a sort of external lock-management server for reliability and availablity, and used to solve asynchronous consensus and other problems in distributed computing.

Building Chubby was an engineering effort required
to fill the needs mentioned above; it was not research.
We claim no new algorithms or techniques. The purpose
of this paper is to describe what we did and why, rather
than to advocate it. In the sections that follow, we de-
scribe Chubby’s design and implementation, and how it
has changed in the light of experience. We describe un-
expected ways in which Chubby has been used, and fea-
tures that proved to be mistakes. We omit details that are
covered elsewhere in the literature, such as the details of
a consensus protocol or an RPC system.

Papers are focused on their overall system architecture as they claimed. Click below to see more detail:

- There is a similar open source called zookeeper.
