Arista EOS® is the world’s most advanced network operating system which provides cloud networking solutions for next-generation data centres and cloud networks.

The Arista cEOS value-proposition brings more software control to the network infrastructure and enables:

  • Customers can develop and test their own applications in containers and then run those same applications in a common container environment on the switches.
  • Customers can simulate large networks by running many instances of cEOS in a containerised server or cloud environment.
  • Flexible platform support. With cEOS running on top of a container runtime environment, the customer now has the flexibility to choose the underlying platform infrastructure, including their own Linux distribution and hardware platforms from third parties.
  • Joint development integration. Many open networking environments rely on containers, and they can benefit from the advanced features of cEOS. For example, Microsoft’s SONiC project leverages cEOS as a way to integrate EOS features into the SONiC stack.
