VERDICT

Should I use Arista?

Data-driven cloud networking (switches, EOS, CloudVision, SD-WAN) - arista.com

Depends. Buy if you run large data center or campus networks with skilled network engineers on staff. Small teams or anyone wanting simple, transparently priced gear should look elsewhere.

Confidence
