- Can service mesh be considered networking at all?
These are all excellent and valid questions. I will try to answer them at the end of the post, but to get there let’s first understand what each solution is trying to achieve and place both on the OSI layer to bring more clarity to this topic.

Before we start, in a nutshell, what is Istio?
Istio (https://istio.io/) Is an Open Source service mesh project led by Google that addresses Continue reading
