container configura�on. Why Cilium? The development of modern datacenter applica�ons has shi�ed to a service- oriented architecture o�en referred to as microservices, wherein a large applica�on is split into to transparently insert security visibility + enforcement, but does so in a way that is based on service / pod / container iden�ty (in contrast to IP address iden�fica�on in tradi�onal systems) and can requests with method GET and path /public/.* . Deny all other requests. Allow service1 to produce on Ka�a topic topic1 and service2 to consume on topic1 . Reject all other Ka�a messages. Require the HTTP

IstioCon 2021 IstioCon 2021 is the inaugural community conference for the industry's most popular service mesh. IstioCon is a community-led event, showcasing the lessons learned from running Istio in production roadmap sessions. Fun and games are also included with two social hours to take the load off and mesh with the Istio community, vendors, and maintainers! #IstioCon Agenda ● Introduction ● Target Audience London ● Have 2 cats @rytswd #IstioCon Briefly about UPSIDER ● Startup providing B2B payment service ● Uses Istio extensively in production ● Headquarter in Tokyo, Japan ● Remote team around the world

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

system. THE GITOPS GUIDE TO BUILDING & MANAGING INTERNAL PLATFORMS 3 weave.works ▼ Self-service developer experience (DX) In the past, the only way a developer could get access to servers, data team delivers self-service APIs to developers. This team builds and maintains the platform that is consumed by development teams. The platform they build is a collection of self-service APIs, tools, services are internal customers of the platform team. In order to properly fulfill its role as an internal service provider, the platform team must take a strategic approach to resource management. “The challenge
