SDN is the N in DevNOps

10

SDN solves every problem …

… if you can ditch legacy

11

SDN brought good BGP software

implementations

12

root@loadbalancer-001:~# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet 37.72.160.20/32 scope global lo

On each loadbalancer:

- service ip

- health script

- BGP software

13

Am I healthy? Tell the network I know how to handle 37.72.160.20

Am I unhealthy? Tell the network I withdraw my knowledge about

37.72.160.20

14

Active nodes announce virtual IP + priority to multiple BGP routers

The network knows which loadbalancers are up and runninng

15

InternetBGP everywhere!

Hey router,I know about37.72.160.20
