http://localhost:8983/portfolio (if running on the local machine) or http://ip>:8983/portfolio (if running remotely - specify the correct IP address of the remote server). This will open the Portfolio Manager RackInferringSnitch RackInferringSnitch infers the topology of the network by analyzing the node IP addresses. This snitch assumes that the second octet identifies the data center where a node is located on Amazon EC2 where all nodes in the cluster are within the same region. Instead of using the node's IP address to infer node location, this snitch uses the AWS API to request the region and availability

Virtual Machine Integration Odyssey, Jimmy Song #IstioCon V0.2 Mesh Expansion ● Prerequisites ○ IP connectivity to the endpoints in the mesh ○ Istio control plane services (Pilot, Mixer, CA) accessible Dnsmasq accepts DNS queries 2. Access the built-in Kube DNS (exposed by ILB) 3. Obtain the Cluster IP resolved 4. Traffic intercepted by the sidecar proxy 5. xDS ■ Traffic forwarded to ingress in the local SVC IP: 10.4.4.4 #IstioCon DNS Issues on VMs accessing K8s SVCs 1. DNS query for httpbin.ns1.svc.cluster.local 2. DNS response – no such host httpbin.ns1.svc.cluster.local SVC IP: 10.4.4.4

(DHCP) to provide you with an IP address. If a Static IP address is required, it will be provided by your network administrator. The following steps are for setting up a static IP address. a. In the Configuration Configuration box, select the Static IP address option. b. Type the IP address of your computer in the IP address box. c. Type the subnetwork (subnet) mask of your computer's IP address in the Subnet mask box box. Note: A subnet mask divides a network of IP addresses into groups, which facilitates routing of data. d. Type the IP address of your ISP in the Gateway address box. Note: A gateway is a device

#IstioCon Accelerate Istio-CNI with ebpf Xu Yizhou & Guo Ruijing #IstioCon Agenda ● Istio-CNI ● tcp/ip stack overhead between sidecar and service ● Background knowledge of ebpf ● Acceleration for Inbound/Outbound/Envoy The Istio CNI plugin replaces the functionality provided by the istio-init container. #IstioCon Tcp/ip stack overhead between sidecar and service Overhead sidecar traffic from 3 scopes ● Inbound ● In the case of Inbound, 4-tuple key may conflict due to same src/dst ip address #IstioCon Use pod ip as hash key Use pod_ip to generate a unique key is a way to distinguish socket from different

for client IP addresses that are in this list. This setting may also be set to an IpRangeList from the external package iptools. This package allows convenient syntax for defining complex IP address ranges ranges. The client IP address is obtained via the CMS_REQUEST_IP_RESOLVER in the cms.middleware.toolbar.ToolbarMiddleware middleware. CMS_REQUEST_IP_RESOLVER default ‘cms.utils.request_ip_resolvers.defau default_request_ip_resolver’ This setting is used system-wide to provide a consistent and plug-able means of extracting a client IP address from the HTTP request. The default implementation should work for

scalability solution. o Activator needs to probe the service endpoint since it cannot access pods by IP directly. And it takes time for Istiod to discover the endpoint of ready pods and then push them Istio mesh on Knative – Reduce mesh size in app sidecar #IstioCon o Knative needs to access POD by IP directly for performance and efficiency. o When mesh enabled, all traffic through Kube service managed
