Network automation infrastructure management tools

Automate network infrastructure management using modern tools and practices for scalable, reliable networking. Network automation tools: 1. Ansible networking: multi-vendor support (Cisco, Juniper, Arista), configuration templates, idempotent operations. 2. NAPALM: vendor-agnostic API, configuration management, operational data retrieval. 3. Nornir: Python framework, parallel execution, inventory management, result processing. 4. Netmiko: SSH connectivity, command execution, configuration deployment across devices. Infrastructure as Code: 1. Network topology: Terraform providers for network devices, automated VLAN provisioning. 2. Configuration templates: Jinja2 templating, device-specific configurations, validation testing. 3. Version control: Git-based network configs, change tracking, rollback capabilities. Network monitoring: 1. SNMP monitoring: network utilization, interface statistics, device health metrics. 2. Flow analysis: NetFlow/sFlow data collection, traffic pattern analysis, capacity planning. 3. Performance baselines: latency (target <10ms), packet loss (<0.01%), bandwidth utilization (<80%). Zero-touch provisioning: 1. DHCP/PXE boot: automated device discovery, configuration deployment, software updates. 2. Network discovery: topology mapping, device inventory, dependency visualization. Security automation: 1. Access control: automated ACL deployment, security policy enforcement. 2. Threat response: automated isolation of compromised devices, traffic redirection. Change management: approval workflows, maintenance windows, automated rollback on failure, configuration backup before changes.
