Description: Service dependency refers to the relationship in which one service requires another to function properly. This concept is fundamental in the realm of Quality of Service (QoS), where the interconnection and interaction between different services are crucial for ensuring optimal performance. Dependency can manifest in various forms, such as the need for a storage service for a web application to operate, or the need for an authentication service to access a system. The main characteristics of service dependency include interdependence, where a failure in one service can affect others, and the need to manage these relationships to ensure service continuity. The relevance of this concept lies in its impact on user experience and operational efficiency of systems. In an environment where services are increasingly complex and interconnected, understanding and managing these dependencies becomes essential to maintain service quality and minimize disruptions. Service dependency also implies the need for proactive monitoring and maintenance to identify and resolve issues before they affect end users, highlighting its importance in the management of modern technological infrastructures.
