 ## Install the required observability features
-The Keptn Lifecycle Toolkit emits OpenTelemetry data as standard but the toolkit does not come pre-bundled with Observability backend tooling. This is deliberate as it provides flexibility for you to bring your own Observability backend which consume this emitted data.

-Over time, we will evolve this application from a simple manifest to a Keptn-managed application. We will install it first with kubectl and add pre- as well as post-deployment tasks. For this, we will check if the entry service is available before the other ones get scheduled. Afterwards, we will add evaluations to ensure that our infrastructure is in a good shape before we deploy the application. Finally, we will evolve to a GitOps driven deployment and will notify an external webhook service when the deployment has finished.
