Why are distributed software systems more complex than centralized software systems?

Distributed software systems are more complex than centralized systems due to factors like network latency, data consistency, and fault tolerance. In a distributed environment, components are spread across multiple locations, which introduces challenges in communication, coordination, and synchronization. Additionally, managing failures and ensuring reliability becomes more intricate as systems must handle potential issues across various nodes. Overall, the increased number of interactions and dependencies in distributed systems adds layers of complexity that are typically absent in centralized architectures.
