Unlocking New Platform Experiences With Open Interfaces

Building beautiful, tailored experiences on top of Kubernetes is hard. Are you building the right abstractions for dev teams to perform their tasks? It is challenging for platform teams to enable such experiences and choose what components they have to build themselves.

Mauricio and Thomas will analyze existing CNCF projects to implement an end-to-end experience and support teams from idea to production, using a “function-as-a-service” example.

They will look into how:
- Knative Serving provides a simplified serverless experience
- Knative Func provides a polyglot CLI tool for developers
- OpenFunction orchestrates the functions lifecycle
- OpenFunction integrates KEDA and Dapr to enable complex use cases.

The presentation will identify the strengths of these tools and which gaps platform teams will need to bridge when building a FaaS experience. The lessons learned and tips shared will help teams bring more projects to their platforms without complicating end-to-end workflows.

28. Don’t do it alone! @salaboy @vitalethomas
29. If you are in this journey… Learn about the companies behind these projects • Knative Serving (https://knative.dev) • Part of Red Hat OpenShift Serverless • Part of VMware Tanzu Platform • APIs adopted by Google Cloud Run @salaboy @vitalethomas
30. If you are in this journey… Learn about the companies behind these projects • Crossplane (https://www.crossplane.io/) • Upbound runs a managed platform, so you don’t need to install and manage Crossplane • Upbound Cloud can be run on your compute, so you have full control on your Crossplane instances
31. If you are in this journey… Learn about the companies behind these projects • Dapr (https://diagrid.io) • Run as a managed service on Azure Container Apps, this means that you have the Dapr APIs available for your containers • Diagrid o ff ers two products • Diagrid’s Conductor to manage and operate Dapr at scale on your Kubernetes clusters • Diagrid’s Catalyst managed service that you can use from any Cloud Provider, including your on-prem setups.
32. If you are in this journey… Learn about the companies behind these projects • Buildpacks (https://buildpacks.io/) • Heroku/Salesforce • VMware Tanzu • Google Cloud • Azure • Bloomberg @salaboy @vitalethomas
33. Takeaways • APIs, standards and open source projects: help you to protect your platform investments • Speedy Onboarding process: simplify and reduce cognitive load from new team members • Out of the Box Cloud-Native patterns: abstract away complexity to reduce cross-environment differences • Smooth Operations: optimise for your use cases, there is no silver bullet @salaboy @vitalethomas
