Cloud and Big Data

The digital universe consists of an estimated 44 zettabytes of data. A zettabyte is 1 million petabytes, or 1 billion terabytes, or 1 trillion gigabytes. In 2019, Google processed approximately 3.7 million queries, YouTube recorded 4.5 million viewed videos, and Facebook registered 1 million logins every 60 seconds. Imagine the computer power to process all these requests, data ingestion, and data manipulation. Common sense tells us that the big IT companies use a lot of hardware to preserve data. A lot of storage needs to be incorporated to prevent limits of capacity.
