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 management-plane processes offloaded to the DPU and the service processes on the host. In this way, applications are unaware of offloading. Only a small amount of service code on the management plane is needed to

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
