salt-master
|
|
===========
|
|
|
|
|
|
|
|
Salt is a new approach to infrastructure management. Easy enough to get running
|
|
in minutes, scalable enough to manage tens of thousands of servers, and fast
|
|
enough to communicate with them in seconds.
|
|
|
|
Salt delivers a dynamic communication bus for infrastructures that can be used
|
|
for orchestration, remote execution, configuration management and much more.
|
|
|
|
