Summary: Gartner’s recommends Web-Scale Networking

More info on: http://go.cumulusnetworks.com/web-scale-dc

Gartner Recommendations:

- Favor vendors that support hardware/software disaggregation.

- Automate relentlessly.

- Foster a culture that manages risks appropriately rather than one that avoids them at all costs.

- Pick a pilot project to gain experience, and demonstrate that the model works.
