I'm currently working on deploying a FaaS solution on a private distributed storage system. I've been searching for a serverless computing tool that can be deployed in custom storage backend, where data can be stored and later processed by executing some client code.
AWS seems to be the most popular option regarding serverless computing implementations. However, it's not open source.
Do you know any alternative to AWS that can be implemented on top of a proprietary storage backend? Thank you in advance for contributing.
