Inter-process communication optimization: The optimized pipe_wait and epoll_wait wakeup mechanisms improve the performance openEuler 21.03 offers refined functions of memory initialization, memory control, statistics, heterogeneous memory, and hot swap, as well as more effective user control interfaces. A series of optimizations

Hubble can answer questions such as: Service dependencies & communication map What services are communicating with each other? How frequently? What does the service dependency monitoring & alerting Is any network communication failing? Why is communication failing? Is it DNS? Is it an application or network problem? Is the communication broken on layer 4 (TCP) or layer 7 (HTTP)

Secure service to service communication based on identities Modern distributed applications rely on technologies such as application required API resources on deathstar, thereby implementing a “least privilege” security approach for communication between microservices. You can observe the L7 policy via kubectl: $ kubectl describe ciliumnetworkpolicies Security Groups Cilium’s AWS Metadata filtering capability enables explicit whitelisting of communication between a subset of pods (identified by Kubernetes labels) with a set of destination EC2 VMs (identified
