Envoy is an open-source extension and service proxy provider, built for cloud-extensive meshes. Envoy - Sidecar proxies per microservice to handle ingress/egress traffic between services in the cluster and from a service to external services. An attribute is a small bit of data that describes a single property of a specific service request or the environment for the request. One of it’s key functions is to abstract away the details of different policy and telemetry backend systems, allowing Envoy and Istio-based services to be agnostic of those backends, which keeps them portable. The Istio proxy contains extensions to the Envoy proxy (in the form of Envoy filters), that allow the proxy to delegate policy enforcement decisions to Mixer. Once Istio is active, you can see visualizations of your Istio service mesh with Kiali, Jaeger, Grafana, and Prometheus, which are all open-source projects that Rancher has integrated with. After the installation, you should see services istio-pilot and istio-mixer in namespace istio-system. The way Istio works with Kubernetes, is that Istio will inject a sidecar traffic proxy called Envoy into each containerized service. Pilot is responsible for the items 1 and 2. Mixer provides a rich intermediation layer between the Istio components as well as Istio-based services, and the infrastructure backends used to perform access control checks and telemetry capture. 4 and above. Envoy captures all incoming and outgoing traffic of its "companion" service, it can then apply some basic operations and also collect data and send it to a central point of decision, called the "mixer" in Istio. Data Plane. Istio is an open source framework for connecting, securing, and managing microservices, including services running on Google Kubernetes Engine (GKE). That has gone through a big rewrite between 0. Istio provides an easy way to create a network of deployed services with load balancing, service-to-service authentication, monitoring, and more, without requiring any changes in service code.
