Arista Extensible Operating System Likes & Dislikes

Like

The great advantage about to use Arista Extensible software is that it is very convenient and easy to get started because we don't have to install any software so we can easily set it up on our system with all the essential softwares that are already bundled. Arista Extensible platform also allows us to download all packages available different repository which makes it easy to install all requirements. It has much fantastic function and features and also it has many compatible programs and documentation.

Like

Arista's products are open and programmable to allow you to customize your own deployments. If you can't develop your own customizations, no problem. Arista takes feature requests seriously not like other well known vendors.

Like

Simplicity, Stability, Innovation

Dislike

One negative aspect that sometimes makes me loses patience that when an application must be installed motivated to the constant problems of the dependence of the programs. Therefore, we have to invest time to install an application that is much higher than the average for other operating systems. Another problem that it has not improved like the other versions of Arista Extensible is the installation of the program and its weakness in the installation of its dependencies because it requires a lot of research and time when installing a certain application.

Dislike

Arista's core business is in Data Center switching and recently announced intentions to enter the campus space. It would be nice to see a product line for the WAN that brings the same great feature set and programmability options

Dislike

Lack of portfolio depth in campus
