Layer7 Networking × Arista Networks

High-performance networking for environments where downtime is not an option.

About Arista Networks

Arista Networks is a dominant force in high-performance data centre and campus networking, purpose-built for environments where packet loss, latency, and downtime are measured in lost revenue. Founded by networking legend Jayshree Ullal, Arista has redefined what enterprise switching and routing look like — replacing legacy monolithic network operating systems with EOS (Extensible Operating System), a Linux-based, single-image, state-driven platform that runs identically across every Arista device.

Arista's portfolio spans data centre switching (100G/400G/800G spine-leaf architectures), campus networking (cognitive Wi-Fi and wired access), network observability (DANZ Monitoring Fabric), and wide-area routing. CloudVision provides a centralised management and telemetry platform that delivers network-wide automation, compliance monitoring, and change validation.

Arista's customers are the organisations that cannot afford network failure: global financial exchanges running latency-sensitive trading, hyperscale cloud providers operating millions of ports, and large enterprises demanding deterministic network performance across their data centre and campus infrastructure.

Why Layer7 Chose Arista Networks

When network performance is non-negotiable — when microseconds matter, when a single dropped packet represents a failed trade or a broken transaction — you deploy Arista. Layer7 partners with Arista Networks because our most demanding clients operate infrastructure where "good enough" networking creates unacceptable business risk.

Arista's EOS architecture resonates with Layer7's operational philosophy. A single binary image across the entire network means consistent behaviour, predictable upgrades, and automation that actually works. CloudVision gives Layer7 the network-wide telemetry and change management capabilities our engineers need to operate complex switching fabrics with confidence — knowing that every change is validated before deployment and every anomaly is visible in real time.

For data centre clients, Arista delivers the switching performance and density that modern workloads demand. For campus clients, the Cognitive Campus brings the same operational maturity to wired and wireless access. Layer7 leverages both to deliver networks that perform predictably, fail gracefully, and scale without architectural redesign.

How Layer7 Delivers Arista Networks

• Data Centre Network Design — Spine-leaf architecture design using Arista 7000/7500 series switches. EVPN-VXLAN fabric design, BGP routing policy, and multi-site interconnection for modern data centre workloads.

• Campus Network Deployment — Arista Cognitive Campus design and rollout: CX-series switches, CloudVision management, and integration with wireless infrastructure for unified wired/wireless access.

• CloudVision Operations — Deployment and management of CloudVision for network-wide telemetry, automated provisioning, compliance monitoring, and change control across the Arista estate.

• Network Monitoring Fabric — DANZ Monitoring Fabric design for network TAP aggregation, packet brokering, and traffic delivery to security and analytics tools — ensuring complete visibility without network disruption.

• Network Automation — Infrastructure-as-code workflows using Arista's open APIs, eAPI, and CloudVision integration with Ansible/Terraform for repeatable, auditable network provisioning.

• Managed Network Operations — Ongoing operational management of Arista infrastructure: firmware lifecycle management, capacity monitoring, fault detection, and performance optimisation delivered as a managed service.
