What are usecase of slave and master

Question

Accepted Answer

Slaves and masters are used in distributed systems for load balancing and fault tolerance.

In a distributed system, the master node controls and coordinates the work of the slave nodes.
Slaves perform tasks assigned by the master and report back their results.
Masters can be used for load balancing, where they distribute tasks evenly among slaves.
Masters can also be used for fault tolerance, where they can detect when a slave node fails and reassign its tasks to other slaves.
Examples include Hadoop, where the master node manages the distribution of data and tasks among slave nodes, and Kubernetes, where the master node manages the deployment and scaling of containerized applications across a cluster of nodes.
