Arista EOS:

Arista EOS: The Modern Solution

In order to address the needs of public / private / hybrid cloud networks, while enabling new applications and ushering in the era of Software Defined Networks (SDN), Arista’s Extensible Operating System (EOS) has been designed from the ground-up and is optimized for these demanding new data center environments.

Arista’s Extensible Operating System is the industry’s most advanced network operating system. It combines modern-day software and operating system (O/S) concepts, transparently restartable processes, open platform development, an unmodified Linux kernel, and a stateful publish/subscribe database model.

In order to fully understand the benefits a true and open operating system provides and explore the potential of a comprehensive automation solution, a detailed review of the underlying architecture of EOS is required. In the following sections we will examine the key components and attributes of EOS architecture as well as the rich array of network services built on top of EOS.
