The CoreOS "Torus" distributed storage system
CoreOS has announced
a new project called Torus which is creating a distributed storage system
for containers. "At its core, Torus is a library with an interface
that appears as a traditional file, allowing for storage manipulation
through well-understood basic file operations. Coordinated and checkpointed
through etcd’s consensus process, this distributed file can be exposed to
user applications in multiple ways. Today, Torus supports exposing this
file as block-oriented storage via a Network Block Device (NBD). We also
expect that in the future other storage systems, such as object storage,
will be built on top of Torus as collections of these distributed files,
coordinated by etcd." The project is quite young, and the current
release is a "prototype version."
