The biggest advantages in Arista Networks Platform for me over the past three years are that it works very well, it is not that noisy (I modified it with silent fans), it was less bulky than Cisco, and it worked very well because it has an extra for a more precise clock, which also helps my use case.

The support of Arista Networks Platform is quite complex; it is not very easy to configure. It needs a lot of network expertise for token sheddings and different kinds of configurations.

The pricing is a little bit higher than Cisco and Juniper, and pricing is the concern.

I would assess CloudVision's impact on my network's control and visibility as okay but not exceptional compared to Cisco solutions like the Nexus Dashboard Fabric Controller.

A weakness would be that in our company, we don't have many people within our team who support the product because there are different vendors, and most of them are not tier-one vendors, so the skills required sometimes are just not there.

The product fails to offer functions related to cloud orchestration, making it in areas where improvements are required.
