Arista Networks review

Best high-performance data-center-to-cloud networking.

Verdict

Arista is the pick for data-center-led teams, because CloudVision extends consistent, high-performance networking and telemetry from its on-premises fabric into cloud environments.

What customers praise

Line-rate hardware, deep telemetry, and CloudVision automation give strong performance and visibility across on-prem and cloud.

What customers criticise

Its center of gravity is the data center, so pure multi-cloud transit is less of a focus than for cloud-native fabrics.

Best for

Data-center-heavy enterprises that want CloudVision-driven networking with consistent operations spanning on-premises fabric and cloud.
