WEBAPP OPS VS NETOPS

1. Install Apache2. Copy files to

/var/www/static_content/3. Copy / update configuration file4. Set up permissions5. Restart Apache6. 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 VLAN2. Query network asset database for free public DMZ /24

IPv4 and /64 IPv6 subnets3. Query network asset database for free VRRP DMZ

group number4. Deploy VLAN to DMZ switching5. Validate VLAN is deployed and active6. Configure IP addressing and VRRP information on

specific DMZ VLAN logical interfaces7. Validate IP logical interfaces are up and responding to

ICMP8. Validate VRRP virtual IP address is active and active

on the correct device.9. Configure the IGP for the new prefix10.Validate the prefix is reachable elsewhere in the IGP

domain11.Validate that the prefix is reachable via the Internet

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
