Func�onality Overview kernel, Cilium security policies can be applied and updated without any changes to the applica�on code or container configura�on. Why Cilium? The development of modern datacenter applica�ons has shi�ed enabled. When to use this mode: This mode has minimal infrastructure and integra�on requirements. It works on almost any network infrastructure as the only requirement is IP connec�vity between hosts

Reliability Messaging Analytics Multi-tenancy caveats ● Single underlying infrastructure ● Reduce operational complexity ○ Infrastructure is operated by a team of 3 engineers ● Reduce costs ● Security issues

(Envoy) and egress (public Internet with exceptions, e.g., SMTP) ○ allow connectivity to needed infrastructure (DNS) and between our own management services ● Feature wish list for Cilium: ? ○ specifying

options. eBee’s fellows were zealous bees, aiming for speed: “We’d go faster, for sure, with buzz code instructions.” “This would be much simpler for us to parse and read.” With his laser screwdriver optimize execution speed. This makes eBPF programs run as efficiently as natively compiled kernel code or as code loaded as a kernel module. Linux supports JIT compilation towards all widespread architectures
