Previously, proprietary hardware performed functions like routers, firewalls, load balancers, etc. In IBM Cloud, we have proprietary hardware like the FortiGate firewall that resides inside IBM Cloud data centers today. These hardware functions are packaged as virtual machine images in a VNF.

Highly available networks are resistant to failures or interruptions that lead to downtime and can be achieved via various strategies, including redundancy, savvy configuration, and architectural services like load balancing. No matter how you slice it, additional instances, hardware, etc., Resiliency.

Since the kernel is basically the software layer between the applications you’re running and the underlying hardware, eBPF operates just about as close as you can get to the line-rate activity of a host. Second, in a busy network, devices such as routers, switches, and firewalls may be very busy operating at a relatively high CPU.

Cloud providers have done such a good job of building resilient networks, with layers of amazing virtualization on top, that network hardware failures rarely become the problem of the network engineer. Consider the edge components of an on-prem network: the expensive routers, switches, and firewalls.
