Final answer:
Salt, also known as Salt Stack, includes an asynchronous file server for efficient distribution of files across multiple servers in a non-blocking manner, which is useful for scaling infrastructure management tasks.
Step-by-step explanation:
The question pertains to Salt, also known as SaltStack, which is a popular open-source configuration management and orchestration tool. One of the features of Salt is an asynchronous file server that allows for efficient distribution of files to multiple servers in a non-blocking manner. This is particularly useful in environments where configuration files and other data need to be distributed across a large number of servers, which can be done simultaneously rather than sequentially, thereby saving time.
An asynchronous file server in Salt enables system administrators and devops professionals to push updates and configurations to managed nodes without waiting for each transaction to complete before starting the next one. This asynchronous communication model is key for scaling infrastructure management tasks effectively.
