Arista Networks Targets Multicloud Networking with CloudEOS

Among the hottest trends across IT in general in 2019 is the move by organization small and large toward multicloud and cloud native. Those are trends that aren’t escaping the notice of Arista Networks which is now launching its new CloudEOS platform to help support those trends.

Challenges that arise when connecting to any cloud can include both performance and security concerns. With CloudEOS, Arista is looking to help solve both those challenges by taking its EOS Linux-based network operating system to new software form factors.

CloudEOS is available as both a virtual machine (VM) as well as in a container format, which makes it easier to manage, deploy and scale software instances in the cloud and on different cloud native platforms. Cloud native is an emerging approach that makes use containers, microservices and APIs to deliver applications, typically with the Kubernetes container orchestration system at the center.

Arista has made CloudEOS is available via the marketplace and service catalogs on Amazon AWS, Microsoft Azure, and Google public clouds. It is also available for deployment in Kubernetes clusters.

Fred Hsu, VP and GM Cloud Networking Software at Arista Networks explained in video launching CloudEOS that it is taking the same EOS code that organizations use today for their networking and is making it consumable by people that are deploying things in a more cloud native way.

Among the benefits cited by Hsu for CloudEOS is it is sold and deployed as a service, rather than as a long term licensed product. The cloud native approach can also scale up and down faster, which is also useful for development and testing as well as to handle specific event.


Arista is also embracing DevOps principles as part of CloudEOS, most notably the concept of infrastructure-as-code.

Hsu explained that Arista is leveraging DevOps tools including HashiCorp’s Terraform and AWS CloudFormation templates to be able to let administrators declaratively provision a cloud router just like they would any other cloud resource. Hsu noted that the beauty is it’s just a few lines of code in a template and CloudEOS will work across multiple clouds.

“Watching a client deploy hundreds of networks, across multiple cloud providers, in minutes without ever touching a network CLI is magical,” stated Douglas Gourlay, vice president and general manager of cloud networking software for Arista. “CloudEOS simplifies networking for any cloud environment, securely, declaratively, and elastically.”
