small independent services that communicate with each other via APIs using lightweight protocols like HTTP. Microservices applications tend to be highly dynamic, with individual containers getting started that need to be updated with a continuously growing frequency. Protocol ports (e.g. TCP port 80 for HTTP traffic) can no longer be used to differentiate between application traffic for security purposes contrast to IP address identification in traditional systems) and can filter on application-layer (e.g. HTTP). As a result, Cilium not only makes it simple to apply security policies in a highly dynamic environment
