The Travels Demo has been deployed in the previous step but without installing any Istio sidecar proxy.

In that case, the application won't connect to the control plane and won't take advantage of Istio's features.

In Kiali, we will see the new namespaces in the overview page:

++++
<a class="image-popup-fit-height" href="/images/tutorial/03-01-overview.png" title="Overview">
    <img src="/images/tutorial/03-01-overview.png" style="display:block;margin: 0 auto;" />
</a>
++++

{nbsp} +
But we won't see any traffic in the graph page for any of these new namespaces:

++++
<a class="image-popup-fit-height" href="/images/tutorial/03-01-empty-graph.png" title="Empty Graph">
    <img src="/images/tutorial/03-01-empty-graph.png" style="display:block;margin: 0 auto;" />
</a>
++++

{nbsp} +
If we examine the Applications, Workloads or Services page, it will confirm that there are missing sidecars:

<a class="image-popup-fit-height" href="/images/tutorial/03-01-missing-sidecar.png" title="Missing Sidecar">
    <img src="/images/tutorial/03-01-missing-sidecar.png" style="display:block;margin: 0 auto;" />
</a>
++++
