Arista CloudEOS review
A cloud-ready virtual router for enterprise WAN, VPN, and multi-cloud routing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Arista CloudEOS is a virtual router and cloud-native networking solution for enterprises and service providers building WAN and multi-cloud networks. It runs as a virtual machine or container, with deployment options spanning public clouds, customer equipment, and supported hypervisors. Routing coverage includes OSPFv2, BGPv4, IS-IS, RIPv2, OSPFv3, and BGPv6, alongside IPsec VPN connectivity, network segmentation, NAT, GRE, and VXLAN routing. Mid-market and enterprise teams that need a core virtual router across several environments are the clearest fit.
Licensing is offered through subscription and cloud consumption models. CloudEOS connects with Arista CloudVision, Terraform, Ansible, Chef, Puppet, Salt, and ServiceNow, giving infrastructure teams several paths for provisioning, orchestration, and operational workflows. Terraform-based provisioning supports repeatable deployment, while management remains available through the CLI, APIs, or CloudVision. The platform runs on Linux-oriented infrastructure and supports self-hosted operation as well as cloud deployment, so it suits organizations that want control over placement and automation rather than a browser-only networking service.
Its standout area is coordinated routing and path control across cloud networks. Dynamic Path Selection uses in-band path telemetry, and Cloud High Availability combines BFD with route failover; telemetry streaming adds network visibility for ongoing operations. AutoVPN and IPsec VPN connectivity extend the design to distributed sites and multi-cloud links. CloudEOS is less suited to buyers seeking a free, open-source, or fully managed SaaS router, since it is paid, proprietary software delivered through infrastructure deployments. Teams choosing it should have networking expertise and an operating model that accommodates virtual machines, containers, or appliances.
