<p>I will install Istio as a service mesh on AWS EKS. I know that Istio provides its own Ingress Gateway. What I am confused about is: <strong>Do we still need to use AWS ALB or ELB in front of Istio Ingress Gateway?</strong></p>

<p>Given that Istio will create <a href="https://github.com/helm/charts/blob/cbd5e811a44c7bac6226b019f1d1810ef5ee45fa/incubator/istio/values.yaml#L110" rel="nofollow noreferrer">a Service for its Ingress Deployment</a> of type <code>LoadBalancer</code>, Kubernetes will take care of provisioning the ELB for you. No need to create it yourself although you could also configure the Service to point to an existing ELB.</p>

<p><em>The linked Service is outdated and for ease of reference only. The latest Istio chart is actually <a href="http://gcsweb.istio.io/gcs/istio-release/releases/1.5.0/charts/" rel="nofollow noreferrer">here</a>. You should be able to download it and confirm the Service configuration.</em></p>
