microservices which will be used to demonstrate various features of the Istio service mesh.</p><h2 id="overview">Overview</h2><p>In this guide we will deploy a simple application that displays information about a book, similar to a single catalog entry of an online book store. Displayed on the page is a description of the book, book details (ISBN, number of pages, and so on), and a few book reviews.</p><p>The Bookinfo application is broken into four separate microservices:</p><ul><li><em>productpage</em>. The productpage microservice calls the <em>details</em> and <em>reviews</em> microservices to populate the page.</li><li><em>details</em>. The details microservice contains book information.</li><li><em>reviews</em>. The reviews microservice contains book reviews. It also calls the <em>ratings</em> microservice.</li><li><em>ratings</em>. The ratings microservice contains book ranking information that accompanies a book review.</li></ul><p>There are 3 versions of the reviews microservice:</p><ul><li>Version v1 doesnt call the ratings service.</li><li>Version v2 calls the ratings service, and displays each rating as 1 to 5 black stars.</li><li>Version v3 calls the ratings service, and displays each rating as 1 to 5 red stars.</li></ul><p>The end-to-end architecture of the application is shown below.</p><div class="figure" style="width: 80%;"><div class="wrapper-with-intrinsic-ratio" style="padding-bottom: 68.52%"><figure> <a href="./img/bookinfo/noistio.svg"> <img class="element-to-stretch" src="./img/bookinfo/noistio.svg" alt="Bookinfo Application without Istio" title="Bookinfo Application without Istio" /> </a></figure></div><p>Bookinfo Application without Istio</p></div><p>This application is polyglot, i.e., the microservices are written in different languages. Its worth noting that these services have no dependencies on Istio, but make an interesting service mesh example, particularly because of the multitude of services, languages and versions for the reviews service.</p><h2 id="before-you-begin">Before you begin</h2><p>If you havent already done so, setup Istio by following the instructions corresponding to your platform <a href="/v0.6/docs/setup/">installation guide</a>.</p><h2 id="deploying-the-application">Deploying the application</h2><p>To run the sample with Istio requires no changes to the application itself. Instead, we simply need to configure and run the services in an Istio-enabled environment, with Envoy sidecars injected along side each service. The needed commands and configuration vary depending on the runtime environment although in all cases the resulting deployment will look like this:</p><div class="figure" style="width: 80%;"><div class="wrapper-with-intrinsic-ratio" style="padding-bottom: 59.08%"><figure> <a href="./img/bookinfo/withistio.svg"> <img class="element-to-stretch" src="./img/bookinfo/withistio.svg" alt="Bookinfo Application" title="Bookinfo Application" /> </a></figure></div><p>Bookinfo Application</p></div><p>All of the microservices will be packaged with an Envoy sidecar that intercepts incoming and outgoing calls for the services, providing the hooks needed to externally control, via the Istio control plane, routing, telemetry collection, and policy enforcement for the application as a whole.</p><p>To start the application, follow the instructions below corresponding to your Istio runtime environment.</p><h3 id="running-on-kubernetes">Running on Kubernetes</h3><blockquote><p>Note: If you use GKE, please ensure your cluster has at least 4 standard GKE nodes.
