Istio scalability optimization during Knative Service provisioning ○ Unleash maximum scalability by fully leveraging Istio features in Knative with service mesh enabled ● Reference Agenda #IstioCon an Ingress Gateway • By default, Knative does not enable service mesh, it uses Istio as an Ingress Gateway. • Enable Secret Discovery Service (SDS) to monitor and mount secrets under istio-system to ingress and knative-local-gateway for cluster local access. They use Istio gateway service istio-ingressgateway as its underlying service. Knative Activator or Application Front door design #IstioCon - Traffic

Istio and all of its components. Istio is a modern service mesh technology stack often used within Kubernetes clusters to provide service-to-service communication, manages TLS certificates, provides workload common environments such as Kubernetes clusters. • Istio Pilot: The service running within the istiod service that handles service discovery. • Istio Ingress/Egress: Networking controls allowing inbound assessment. A test plan was created which matched areas of code with specific security controls (e.g. service discovery, certificate lifecycle, side car injection) to focus testing efforts. Istio does not currently
