Is Google Drive a distributed system?

Could you clarify if Google Drive operates as a distributed system? I'm curious to know if it leverages multiple servers and data centers to store and manage files, ensuring high availability, scalability, and fault tolerance. Is there a decentralized approach in its architecture, where data is replicated across various locations for redundancy and faster access? Additionally, does it utilize distributed computing principles to process and manage the vast amounts of data it handles? Understanding these aspects would provide valuable insights into the workings of Google Drive's backend infrastructure.
