masterslavemodellen

The masterslave model, often referred to as the master-slave model, is a conceptual framework used to describe certain types of distributed systems and relationships between entities. In this model, one entity, designated as the "master," holds control and dictates operations, while another entity, the "slave," receives instructions and performs tasks as directed by the master. This hierarchical structure is characterized by a clear division of roles and responsibilities.

This pattern is prevalent in various technological contexts. For instance, in some database architectures, a master database may handle write operations and replicate data to slave databases, which are primarily used for read operations. This setup can improve performance and availability by distributing the workload. In computing clusters, a master node might manage job scheduling and resource allocation, while slave nodes execute the assigned tasks.

The terminology "master-slave" has drawn criticism for its potentially negative connotations, leading to the adoption of alternative terms in some fields. More neutral phrases like "primary-replica," "leader-follower," or "controller-agent" are increasingly being used to describe similar relationships in distributed systems, aiming to promote inclusivity and avoid problematic language. Despite the terminological shift, the underlying principle of a controlling entity directing subordinate entities remains a fundamental concept in understanding certain system designs.
