Google never said how many servers are in its data center, but an engineer at Google said in a recent speech that their target has been targeted at millions or even 10 million servers.
Jeff Dean, Google Retrieval System Architect, gave a keynote speech at a seminar organized by the American Computer Society (ACM) to talk about large-scale distributed systems, it also elaborated on some technical details of Google's infrastructure in this regard, and revealed how they managed dozens of data centers around the world.
Jeff Dean also mentioned a new storage and Computing System "spanner" that Google is currently developing. It is mainly used for automatic management of Google services across multiple data centers, data and computing can be automatically and dynamically arranged around the world, and latency and cost can be minimized.
It is said that this system can manage 100 trillion-1018 servers, 1 billion directories, bytes of data (1zb/000000pb),-data centers, and clients.
