Juniper Hardware Overview
Juniper provides switching, routing, and security platforms for enterprise, service provider, and data center networks. Many organizations standardize on Juniper for scalability, security, and automation through Mist AI and Junos OS.

Key advantages of Juniper hardware include:

Consistent Junos OS across switches, routers, and firewalls
EVPN-VXLAN support on QFX, EX, and MX families
Mist AI integration for automation and cloud management
Strong security with SRX firewalls
Long lifecycle and excellent secondary-market ROI

For campus switching, customers commonly deploy EX3400, EX4300, and EX4400. For data center EVPN-VXLAN fabrics, popular platforms include QFX5100, QFX5120, and QFX5200.
