Some tra�c �ows between the data center and end users, some tra�c �ows between data centers, and some tra�c stays within the data center.

Where Does This Data Center Tra�c Originate?

By 2020, tra�c between data centers and end users will reach 2.2 ZB annually (14% of total data center tra�c).

1.4 ZB (9%) will come from tra�c between

data centers, such as replication and

interdatabase links.

But the vast majority of data center tra�c, 11.7 ZB (77%), will still be coming from within the data center, such as storage,

production, development, and authentication tra�c.
