Cilium is open source so�ware for transparently securing the network connec�vity between applica�on services deployed using be started in a short period of �me. Typical container firewalls secure workloads by filtering on source IP addresses and des�na�on ports. This concept requires the firewalls on all servers to be manipulated scale and supports direct server return (DSR) if the loadbalancing opera�on is not performed on the source host. Note: load balancing requires connec�on tracking to be enabled. This is the default. Monitoring

Typical container firewalls secure workloads by filtering on source IP addresses and destination ports. This concept requires the firewalls on all servers to be manipulated (DSR) as well as Maglev consistent hashing if the load balancing operation is not performed on the source host. For east-west type load balancing, Cilium performs efficient service-to-backend translation
