Innovations Ease Migration to Cloud Scale Networking

SANTA CLARA, Calif.,--January 19, 2016 -- Arista Networks (NYSE:ANET) today announced the next phase of Arista EOS (Extensible Operating System), enabling customers to focus on real-time migration from legacy enterprise silos to private, public and hybrid cloud networking. This evolution is based on three powerful building blocks: Infrastructure, Hybrid Cloud and Container Support.

Arista EOS is the industry’s only open and programmable, state-driven, publish-subscribe-notify architecture built for cloud networking. Building upon Arista's state driven system-level SysDB concept, Arista introduces NetDBTM, a network-wide state repository that increases network scalability, agent efficiency, and resilience.

“The infrastructure underlying a network operating system is the foundation for delivering a flexible and resilient solution to customers. Arista EOS, originally built on a state-sharing database, has proven stable and scalable in the largest cloud networking environments. Today’s NetDB introduction represents our continued investment in Arista EOS, as it evolves to meet the changing needs of the cloud,” said Ken Duda, CTO and Senior Vice President of Software Engineering for Arista.

Essential Elements for Cloud Design

Infrastructure - NetDB expands the network roles for Arista’s spine platforms. With NetDB enhancements, EOS now supports in excess of 1 million routes and 100,000 tunnels for increased cloud scale. NetDB also provides the ability to aggregate the network state of all EOS devices to a common point through the CloudVision® platform and, from there, stream network-wide telemetry data to improve network operations visibility and historical analytics.

Built with extensibility at its core, EOS continues to evolve its API infrastructure with new support for agents written in the increasingly popular Go programming language, as well as support for OpenConfig APIs and data models.

Hybrid Cloud - Arista EOS features support for workload migration between private and public workloads and CloudVision management for hybrid cloud solutions. By delivering appropriate EOS Tracer tools for cloud-bursting, enterprise customers can now seamlessly execute their hybrid cloud roadmap. This bridges the gap between private and public clouds.

Container Support - Arista EOS extends its virtualization support by adding both the ability to run Docker containers on EOS, as well as improved physical and virtual visibility with Container Tracer. Container support in EOS offers customers the flexibility to load container-based applications directly onto the Arista EOS platform. Complementing visibility tools for bare metal and hypervisor designs, Container Tracer delivers advanced monitoring capabilities for emerging container-based applications.

Product Availability

The NetDB EOS enhancements are integrated into the latest EOS releases and are transparent to customer deployments. This natural evolution maintains the same single binary image philosophy and non-disruptive upgrade capabilities.

The additional new infrastructure enhancements will be generally available in Q1 2016.

Arista will host a technical webinar and tutorial around the EOS Evolution on February 18, at 10:00 AM PT. Please register here:
