 It is possible to have a public IP instead (i.e an actual external load balancer) by creating a Service of type [LoadBalancer](https://kubernetes.io/docs/tasks/access-application-cluster/create-external-load-balancer/). Do feel free to play around with it!
 
-The above exercises a pretty good exposure to using Kubernetes to manage large scale deployments. Trust me, the process is very similar to the above for operating 1000 deployments and containers too! While a Deployment object is good enough for managing stateless applications, Kuberenetes provides other resources like Job, Daemonset, Cronjob, Statefulset etc. to manage special use cases.

 ## Advanced topics
 Most often than not, microservices orchestrated with Kubernetes contain dozens of instances of resources like deployment, services and configs. The manifests for these applications can be auto- generated with Helm templates and passed on as Helm charts. Similar to how we have PiPy for python packages there are remote repositories like Bitnami where Helm charts (e.g for setting up a production-ready Prometheus or Kafka with a single click) can be downloaded and used. [This is a good place to begin](https://www.digitalocean.com/community/tutorials/an-introduction-to-helm-the-package-manager-for-kubernetes).
 
-Kuberenetes provides the flexibility to create our custom resources (similar to Deployment or the Pod which we saw). For instance, if you want to create 5 instances of a resource with kind as  SchoolOfSre you can! The only thing is that you have to write your custom resource for it. You can also build a custom operator for your custom resource to take certain actions on the resource instance. You can check [here](https://www.redhat.com/en/topics/containers/what-is-a-kubernetes-operator) for more information.
