# IBM Event Streams

{% hint style="success" %}
Lenses will not start without a valid Kafka Connection. You can either add the connection via the bootstrap wizard or use [provisioning ](/latest/devx/5.5/deployment/installation/automation.md)for automated deployments.
{% endhint %}

From the IBM Cloud console, locate your **`bootstrap_endpoints`**. for the service credentials you want to connect with.

In the Lenses bootstrap UI:

1. Set the bootstrap\_endpoints as bootstrap servers
2. Set **`SASL SSL`** as the security protocol
3. Set **`PLAIN`** as the security mechanism
4. Set the\*\*`jaas.conf`\*\* as the following, using the apiKey value as the password.

```bash
org.apache.kafka.common.security.plain.PlainLoginModule required
username="token"
password="[Your API KEY]"
```

{% hint style="info" %}
IBM Event Streams requires a replication factor of 3. Ensure you set the replication factor accordingly for Lenses internal topics.

See [Configuration](https://github.com/lensesio-dev/docs/blob/master/deployment/prepare-your-environment/configuration-reference.md#lenses-internal-kafka-topics).
