Ulises_Alonso great article! Can I ask when CNF are used and when it is better to use BIG-IP Next SPK as I am still not clear on that part?

    Hi Nikolay

    Sorry for the overlook, I was away when you posted this.

    CNFs are meant mainly for 5G user plane traffic (pass through traffic) and SPK are meant for ingress/egress traffic to PODs hosted in the cluster. Both SPK and CNF are going to be re-branded/re-architected under the common BNK product (BIG-IP Next for Kubernetes) 

    I hope this clarifies it
