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.
