Not necessarily - I think the target audience is different.

If you are administering an internal datacenter in a company, then you can utilize this to offer a serverless env. to application developers in your company, and then those developers would benefits similar to that of AWS lambda/CF workers etc.

Someone will obviously have to manage servers, but in addition to it, it is also quite a bit of work to support orchestration of ephemeral functions, and a nice open source framework is definitely a huge help there.
