A salt is:
A solution for configuration management. Salt can keep distant nodes in predetermined states. For instance, it can make sure certain services are active and certain packages are installed.
A distributed remote execution system that is employed to run commands and make data requests on distant nodes. Using arbitrary selection criteria or on specific nodes, Salt is capable of querying and executing commands.
It was created to improve, accelerate, and further customize the best remote execution options now available. Salt can handle massive amounts of data quickly through a straightforward and manageable interface, and not only dozens or even hundreds or even thousands of separate servers.
Simplification
It may appear difficult to provide flexibility between enormous scale deployments and smaller systems, yet Salt development is incredibly easy to set up and manage, regardless of the project’s size. Any number of servers can be used with Salt’s architecture, from a few local network systems to several international installations across various data centers. The topology is a straightforward server/client architecture with just one group of daemons providing all the necessary functionality. Salt can be fine-tuned to match needs, even if the default configuration will function with little to no adjustment.
