Istio is an open platform for providing a uniform way to integrate microservices, manage traffic flow across microservices, enforce policies and aggregate telemetry data. Envoy can be classified as a tool in the "Load Balancer / Reverse Proxy" category, while Istio is grouped under "Microservices Tools".

Likewise, people ask, what does Istio stand for?

Traffic management and policy control Istio traffic management lets you control the flow of traffic and API calls between services and gives you better visibility into your traffic, helping you catch issues before they cause problems.

One may also ask, how does Envoy sidecar work? In this deployment model, Envoy is deployed as a sidecar alongside the service (the http client in this case). When the http-client makes outbound calls (to the “upstream” service), all of the calls go through the Envoy Proxy sidecar.

What is envoy service mesh?

A Service Mesh uses sidecars to handle outbound traffic for each service instance. This allows Envoy to handle load balancing and resilience strategies for all internal calls, as well as providing a coherent layer for observability. That's where the Envoy service mesh comes in.

Does Istio require Kubernetes?

Before you can install Istio, you need a cluster running a compatible version of Kubernetes. Istio 1.4 has been tested with Kubernetes releases 1.13, 1.14, 1.15. A cluster is set of compute nodes that run containerized applications. Typically, the compute nodes comprising a cluster can reach each other directly.

Why do we need Istio?

Istio lets you connect, secure, control, and observe services. At a high level, Istio helps reduce the complexity of these deployments, and eases the strain on your development teams. It is a completely open source service mesh that layers transparently onto existing distributed applications.

How do you pronounce Istio?

Istio in Greek means sail (the noun). If they pronounce it like in Greek it should be pronounced like east-E-o or e-stEE-o or something

Who created Istio?

IBM

What is a service mesh and why do I need one?

A service mesh, like the open source project Istio, is a way to control how different parts of an application share data with one another. Unlike other systems for managing this communication, a service mesh is a dedicated infrastructure layer built right into an app.

How does Istio work with Kubernetes?

The Kubernetes Service Mesh: A Brief Introduction to Istio. Istio is an open source service mesh designed to make it easier to connect, manage and secure traffic between, and obtain telemetry about microservices running in containers. As of this writing, Istio focuses mostly on Kubernetes.

How do I use Istio with Kubernetes?

In This Guide:
  1. Before You Begin.
  2. Create Your Kubernetes Cluster. Install Helm.
  3. Install Istio. Install Helm Charts. Set up Envoy Proxies.
  4. Install the Istio Bookinfo App. Open the Istio Gateway. Apply Default Destination Rules.
  5. Visualizations with Grafana.
  6. Removing Clusters and Deployments.

Is Istio production ready?

Built on the back of Envoy, CNCF's network proxy that originally came out of Lyft, Istio reached its production-ready 1.0 release in July 2018 and is currently up to version 1.3.

Is Kubernetes a service mesh?

According to Stefan, a service mesh is a dedicated infrastructure layer for handling service-to-service communication. Although this definition sounds very much like a CNI implementation on Kubernetes, there are some differences. A service mesh typically sits on top of the CNI and builds on its capabilities.

What is Istio Gateway?

In an Istio service mesh, a better approach (which also works in both Kubernetes and other environments) is to use a different configuration model, namely Istio Gateway . A Gateway allows Istio features such as monitoring and route rules to be applied to traffic entering the cluster.

Why do we need Service Discovery?

One great benefit of this pattern is that details of discovery are abstracted away from the client. Clients simply make requests to the load balancer. This eliminates the need to implement discovery logic for each programming language and framework used by your service clients.

What is Istio proxy?

Istio Proxy. The Proxy can inject client identity, either through connection tunneling or protocol-specific mechanisms such as JWT tokens for HTTP requests. Monitoring & Logging. The Proxy can report client-side metrics and logs to the Mixer.

What is Istio mixer?

Mixer is the Istio component responsible for providing policy controls and telemetry collection: Mixer Topology. The Envoy sidecar logically calls Mixer before each request to perform precondition checks, and after each request to report telemetry.

What is Istio sidecar?

In simple terms, sidecar injection is adding the configuration of additional containers to the pod template. The added containers needed for the Istio service mesh are: istio-init This init container is used to setup the iptables rules so that inbound/outbound traffic will go through the sidecar proxy.

What is a sidecar application?

Deploy components of an application into a separate process or container to provide isolation and encapsulation. This pattern can also enable applications to be composed of heterogeneous components and technologies. This pattern is named Sidecar because it resembles a sidecar attached to a motorcycle.

What is sidecar proxy?

A sidecar proxy is an application design pattern which abstracts certain features, such as inter-service communications, monitoring and security, away from the main architecture to ease the tracking and maintenance of the application as a whole.

What does a service mesh do?

A service mesh is a dedicated infrastructure layer that controls service-to-service communication over a network. It provides a method in which separate parts of an application can communicate with each other. Service meshes appear commonly in concert with cloud-based applications, containers and microservices.
