Affordable for enterprise-sized companies
Speaking about whether the product enhanced our company's data center scalability, I would say that it was a solution that was used in a banking company, where it served as a replacement for Cisco. Though Arista Networks Platform is similar to Cisco IOS CLI, I feel that the former product offers better prices compared to the latter tool. Arista Networks Platform office is more efficient at a lower cost. I recommend the product to those who plan to use it. The tool is stable and cheaper than Cisco. I would say that Arista Networks Platform is 100 percent compatible with the existing infrastructure in my company. The impact of the tool's network telemetry on our company's troubleshooting practices was just good for the scope for which I need the product. I rate the overall tool a nine out of ten.

Virtual chassis technology enhances connectivity and simplifies management
Juniper EX series switches offer great technology, particularly their Virtual Chassis technology, which is an excellent feature for stacking switches and functions like a single virtual switch. The EX series provides a separation of control, management, and data planes, reducing the attack surface area, ensuring a lesser extent of vulnerability. The PoE budget is commendable, and they manage connectivity effectively.

Benefits of Juniper vs Cisco
Both are decent products. I prefer Juniper for the following reasons: 1) Cleaner separation of data plane from control plane. Higher end Cisco devices are better at this but most of the lower end products still seem to be more integrated than I like. 2) The Hierarchical config design means I can…
