Cilium in Production
“Cilium enabled us to acquire more sophisticated customers.”
“Cilium is just stable. We have been running it in production for almost 5 years and we haven’t had any major incidents in the dataplane which is very important for our applications.”
“To us, Cilium is a single solution that covers a large number of our platform feature requirements. Before, we couldn’t find a single solution to all of our challenges but when we used Cilium, it was a perfect match.”
