collaborative scheduling of service containers and OSs. • API O&M: Kubernetes-native declarative APIs are used to manage and maintain OSs in a standard manner. • Atomic management: Based on the Kubernetes Features • Compatible with the native Kubernetes system: Capabilities are extended based on extended APIs of native Kubernetes. • Compatible with the openEuler system: Enhanced features (such as hierarchical Lightweight: running in an environment with only tens of KB of memory • Universality » POSIX-compliant APIs » Compatible with multiple instruction set architectures (ISAs) such as x86, AArch64, and Cortex-M

communicating with each other? How frequently? What does the service dependency graph look like? What HTTP calls are being made? What Kafka topics does a service consume from or produce to? Network monitoring Is it an application or network problem? Is the communication broken on layer 4 (TCP) or layer 7 (HTTP)? Which services have experienced a DNS resolution problem in the last 5 minutes? Which services monitoring What is the rate of 5xx or 4xx HTTP response codes for a particular service or across all clusters? What is the 95th and 99th percentile latency between HTTP requests and responses in my cluster

applica�on is split into small independent services that communicate with each other via APIs using lightweight protocols like HTTP. Microservices applica�ons tend to be highly dynamic, with individual containers that need to be updated with a con�nuously growing frequency. Protocol ports (e.g. TCP port 80 for HTTP traffic) can no longer be used to differen�ate between applica�on traffic for security purposes as contrast to IP address iden�fica�on in tradi�onal systems) and can filter on applica�on-layer (e.g. HTTP). As a result, Cilium not only makes it simple to apply security policies in a highly dynamic environment
