from where can I learn the fundamentals on this topic. I tried searching for data plane but most of them are k8s specific and few of them were pointing to layer3 of OSI model but I couldn't understand maybe my fundamentals are not too strong.Any reference such as books or articles will be much appreciated
This could be too high level, but I stumbled onto the founder's (crawshaw) website and found one of his blog posts very helpful for understanding basic fundamentals of the product (i.e. Zero Trust networks and microsegmentation)
