- 25. 25 WEBAPP OPS VS NETOPS 1. Install Apache 2. Copy files to /var/www/static_content/ 3. Copy / update configuration file 4. Set up permissions 5. Restart Apache 6. Test To Deliver Static Content on Apache Add a new DMZ VLAN, IP addressing, VRRP group and IGP advertisement to a DMZ pair of switches: 1. Query network asset database for free DMZ VLAN 2. Query network asset database for free public DMZ /24 IPv4 and /64 IPv6 subnets 3. Query network asset database for free VRRP DMZ group number 4. Deploy VLAN to DMZ switching 5. Validate VLAN is deployed and active 6. Configure IP addressing and VRRP information on specific DMZ VLAN logical interfaces 7. Validate IP logical interfaces are up and responding to ICMP 8. Validate VRRP virtual IP address is active and active on the correct device. 9. Configure the IGP for the new prefix 10.Validate the prefix is reachable elsewhere in the IGP domain 11.Validate that the prefix is reachable via the Internet
- 26. 26 TOOLS POINT OF VIEW DEVOPS NETOPS Designed to deploy and configure server infrastructure, software & applications Used to generate, load and validate configuration for interrelated network applications Designed to ensure correct versions of applications are installed and running Applications are often sealed in to the OS unless on Network *nix Can be used to scale to hundreds of thousands of servers and reduce deployment time Used to remove repetitive nature of configuration and human error, automate network engineering feedback loops and automate deployment Can be used to finger print environment and for compliance Can be used to harvest interrelated and distributed network ‘big data’ and for compliance checking

Editor's Notes
- Complex - networks are a complex ecosystem inter-connected devices ●Services are spread over multiple systems ●Equipment is often heterogeneous ●Require a lot of planning, testing, and validation ●Network devices have historically been closed systems with vendor specific CLIs ●They often differ between the same vendor device types and versions. ●Vendors slow to introduce features, sometimes 18-24 months - upgrade cycle is just as long.
