Vendor lock-in can be a worry for many engineers . A new innovative approach, will for the first time, allow open-source serverless to run on AWS Lambda or Kubernetes using the same deployment artefact, packaged using the tools we love: containers. OpenFaaS is an open-source function as a service (FaaS) platform on the [CNCF serverless landscape](https://landscape.cncf.io/format=serverless). With OpenFaaS you can package anything as a serverless function and deploy to Kubernetes using containers. Due to UNIX-like primitives in the core architecture, it was possible to extend the system to run functions on both Kubernetes and AWS Lambda depending on user preference. The core components of OpenFaaS still run on Kubernetes but the functions are deployed and invoked on AWS Lambda
