SaltStack
SaltStack (now often called Salt) is an open-source configuration management and remote execution tool used for automating IT infrastructure. It enables administrators to manage and control large numbers of servers and network devices from a central location using a master-minion architecture. It supports event-driven automation, real-time monitoring, and cloud orchestration.
Developers should learn SaltStack for managing complex, scalable infrastructure in environments like data centers, cloud deployments, and DevOps pipelines. It is particularly useful for automating server provisioning, configuration enforcement, and software deployment across heterogeneous systems, offering high-speed execution and flexibility through its Python-based modules and YAML-based state files.
