The document discusses the integration of Kubernetes and AWS Lambda, particularly how to use OpenFaaS to deploy functions within these environments. It highlights benefits such as managed infrastructure, portability, and ease of use, while also demonstrating various deployment and invocation methods. Future plans include enhancements to OpenFaaS and increasing template support.

18. Why use OpenFaaS on Lambda?
• Migration path to k8s and multi-cloud
• Legacy integration with proprietary services
• Managed infrastructure
• Bursting / Free tier

19. Benefits of OpenFaaS on Kubernetes
• Portability
• Control over timeouts / scaling
• Memory, CPU and networking
• Ecosystem benefits
