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.

## Enabling Service Mesh

## Enabling Istio
|
||||
|

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. From the **Global** view, navigate to the cluster that you want to configure the service mesh for.
|
||||
|
||||
1. Select **Tools > Service Mesh** in the navigation bar.
|
||||
1. Select **Tools > Istio** in the navigation bar.
|
||||
|
||||
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/service-mesh/istio/). Enter in your desired configuration options. Ensure you have enough resources for the service mesh and on your worker nodes to enable the service mesh.
|
||||
|
||||
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.

In the create and edit namespace page, you can enable or disable [Istio sidecar auto injection](https://istio.io/blog/2019/data-plane-setup/#automatic-injection). When you enable it, Rancher will add `istio-injection=enabled` label to the namespace automatically.
