The World’s Most Advanced Network Operating System
Arista EOS is the core of Arista cloud networking solutions for next-generation data centers and cloud networks. Cloud architectures built with Arista EOS scale to tens of thousands of compute and storage nodes with management and provisioning capabilities that work at scale. Through its programmability, EOS enables a set of software applications that deliver workflow automation, high availability, unprecedented network visibility and analytics and rapid integration with a wide range of third-party applications for virtualization, management, automation and orchestration services.
Arista Extensible Operating System (EOS) is a fully programmable and highly modular, Linux-based network operation system, using familiar industry standard CLI and runs a single binary software image across the Arista switching family. Architected for resiliency and programmability, EOS has a unique multi-process state sharing architecture that separates state information and packet forwarding from protocol processing and application logic.

Open integration with all application and infrastructure elements via eAPI and Advanced Event Manager (AEM)
Programmable at all layers: Linux kernel, hardware forwarding tables, switch configuration and CLI, switch control plane as well as management layer. This programmability of EOS enables rapid integration with a wide range of third-party applications for virtualization, management, automation, orchestration and network services
EOS Application Extensibility for the ability to run cloud infrastructure automation applications (such as Chef, Puppet or Ansible) and network analytics applications (such as Splunk)
Easily adaptable to in-house network management systems
Key enabler of Arista EOS software applications for automation and visibility, such as Zero Touch Provisioning, VM Tracer, and Latency Analyzer (LANZ).
Simplified provisioning for new and replacement switches with Zero Touch Provisioning (ZTP) and Zero Touch Replacement (ZTR)
Advanced Event Management for automated responses to network and application events
Automate complex IT workflows and simplify network operations to individual requirements through rich programmatic capabilities
Automation Integration with partners enhance native capabilities with tools such as Puppet, Chef and Ansible and extends automation up the stack to include other network systems and applications including firewalls, load balancers and compute infrastructures with partners such as F5 and VMware.
