We had (have) discovery, auto-scaling and redundancy in PaaS. Most apps could run just fine in Cloud Foundry/App Engine/Beanstalk/Heroku. But the devs insist on MongoDB & Jenkins instead of using the cloud-provider solution and now you're back to defining VPCs, scaling policies, storage and whatnot.
Knative does exactly that. You can use your buildpacks and everything in Tekton and configure your application via Knative Services. No need to bother about anything else.
