configuration. Why Cilium? The development of modern datacenter applications has shifted to a service-oriented architecture often referred to as microservices, wherein a large application is split into to transparently insert security visibility + enforcement, but does so in a way that is based on service / pod / container identity (in contrast to IP address identification in traditional systems) and requests with method GET and path /public/.*. Deny all other requests. Allow service1 to produce on Kafka topic topic1 and service2 to consume on topic1. Reject all other Kafka messages. Require the HTTP header

each openEuler release. In addition, each release is built on feedback given by community users to bridge the gap between innovation and the community, as well as improve existing technologies. openEuler introduces the concept of the versatile-scenario OS, which achieves flexible version build and service composition through a full-stack atomization decoupling and Lego-style architecture, making it can continue managing processes on the host side. The DPUDirect feature significantly reduces service offloading costs in DPU scenarios, simplifies O&M, and significantly reduces subsequent maintenance

Hubble can answer questions such as: Service dependencies & communication map What services are communicating with each other? How frequently? What does the service dependency graph look like? What HTTP HTTP calls are being made? What Kafka topics does a service consume from or produce to? Network monitoring & alerting Is any network communication failing? Why is communication failing? Is it DNS? Is it requests? Application 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

cloud-native CPU scheduling algorithms for hybrid service deployments and KubeOS for containers. As an OS platform, openEuler releases an updated long-term service (LTS) version every two years. Each LTS version each openEuler release. In addition, each release is built on feedback given by community users to bridge the gap between innovation and the community, as well as improve existing technologies. openEuler algorithm against out of memory (OOM) allows online services to run reliably based on their higher service priorities. • EulerFS: A new file system is designed for non-volatile dual in-line memory modules

local or remote, include CLI and GUI, support bash, ssh, vnc, web vnc and web ssh Network Builtin bridge networking, every board has network (except Raspi3) Boot Support serial port, curses (bash/ssh friendly) command works without sudo and without any issue: 1 $ docker run hello-world In China, to use docker service normally, please must configure one of chinese docker mirror sites, for example: • Aliyun Docker /lib/systemd/system/docker.service 5 ExecStart=/usr/bin/dockerd -H fd:// --bip=10.66.0.10/16 Please restart docker service and lab container to make this change works: 1 $ sudo service docker restart 2 $
