CloudVision is Arista’s centralized platform for network management, automation, and analytics, designed to simplify operations across the entire network lifecycle.
Key capabilities include:
- Zero-touch provisioning and automation
- Real-time telemetry and analytics with a network-wide data lake
- Centralized visibility across data center, campus, WAN, and cloud
- AI/ML-driven insights for proactive operations
CloudVision enables organizations to move toward a Network-as-a-Service model, reducing operational complexity and improving efficiency.
Network Automation & Telemetry
Arista integrates advanced network automation and real-time telemetry across its portfolio, enabling organizations to monitor, analyze, and optimize network performance.
With streaming telemetry and analytics, teams gain:
- End-to-end network visibility
- Faster troubleshooting and root-cause analysis
- Proactive performance optimization
This is critical for modern environments where cloud, AI, and distributed systems require continuous monitoring and rapid response.
Case Study by Arista Networks
Modernizing Data Center HPC with Arista CloudVision and 400G Networking
CEA’s Military Applications Division faced scalability and performance limitations in its high-performance computing (HPC) environment due to a legacy InfiniBand network, which restricted expansion and future growth.
To address this, CEA deployed Arista’s 400Gb/s Ethernet-based leaf-spine architecture, powered by Arista EOS and CloudVision. This solution delivered higher throughput, lower latency, improved workload flexibility, and a clear roadmap to 800Gb/s, enabling a scalable, future-ready HPC infrastructure.
