Using Rancher, you can connect, secure, control, and observe services through integration with [Istio](https://istio.io/), a leading open-source service mesh solution. Istio provides behavioral insights and operational control over the service mesh as a whole, offering a complete solution to satisfy the diverse requirements of microservice applications.

As an [administrator]({{< baseurl >}}/rancher/v2.x/en/admin-settings/rbac/global-permissions/) or [cluster owner]({{< baseurl >}}/rancher/v2.x/en/admin-settings/rbac/cluster-project-roles/#cluster-roles), you can configure Rancher to deploy Istio to your Kubernetes cluster.
|
||||
|

1. Select **Enable** to show the [Service mesh configuration options]({{< baseurl >}}/rancher/v2.x/en/cluster-admin/tools/service-mesh/istio/). Enter in your desired configuration options. Ensure you have enough resources for service mesh and on your worker nodes to enable service mesh.

1. Select **Enable** to show the [Istio configuration options]({{< baseurl >}}/rancher/v2.x/en/cluster-admin/tools/istio/config/). Enter in your desired configuration options. Ensure you have enough resources on your worker nodes to enable Istio.
|
||||
|
||||
1. Click **Save**.
|
||||
|
||||
**Result:** The Istio application, `cluster-istio`, is added as an [application]({{< baseurl >}}/rancher/v2.x/en/catalog/apps/) to the cluster's `system` project. After the application is `active`, you can start using Istio.
|
||||
|
||||
> **Note:** When enabling service mesh, you need to ensure your worker nodes and Istio pod have enough resources. In larger deployments, it is strongly advised that the service mesh infrastructure be placed on dedicated nodes in the cluster.
