Why Data Centers Are Suddenly Everywhere
All of these data centers are not showing up by accident. They are the physical response to a change in how the internet is used.
The three pillars of Data Center design
For network engineers, data center design goes beyond switches and routers. The goal is to create an environment where failures are predictable and repeatable, not just to ensure basic functionality.
