This enables us to fully reuse the existing code to consume a wide range of web service events without rewriting the code.

There are several serverless frameworks out there in the cloud-native landscape. However, some problems need to be addressed by Alex Ellis, the original author of OpenFaaS. The driving factor behind the making of the framework is shaping the following, compelling features:
- Ease of use: Basically, many serverless frameworks are complex to deploy by nature, as they...
