No, but I don't think it's significantly difficult to duplicate either. It's just the sum of my experience w/ various cloud providers and an opinionated/best-practices way to run things.
I sell my services and this is a huge enabler in my work. I don't necessarily see the benefit of outside contributors. As an educational tool it also kind of doesn't make total sense without context of how things work in the various cloud services.
So while I kind of want to, it's also sort of my competitive edge and interaction with the community is a drain on my time without adding much to my bottom line. That is to say, I've opened pieces of this previously and all it did was bring tons of demands on my time without any paying clients (and I already get enough inbound that I don't need more name recognition).
As a side note though, Terraform has probably made more of a difference to my career than any other piece of software. Shoutouts to Hashicorp, really. Consul, Vault and Packer also have been majorly useful but to a lesser degree.
They've really put a lot of money in my pocket and that's the best feature any software can have. :D
I'm curious about your services ... Do you offer them à la carte or as a one-time IaC / DevOps setup or some kind of subscription or other? How is pricing determined? Do you have technical support and SLA?
Most of my work comes through people/companies I've previously worked with and recommendations. As much as possible I try to set things up so they rely on their cloud provider for support, but most questions are either simple enough that I share my advice freely or can charge a day rate to do some work. I insist on working with at least one person to own the accounts & code/state (which can be like paid training for them). They may be paying for my knowledge/experience, but I prefer to leave them artifacts to reference after I'm done.
I charge reasonable contractor rates per diem.
I also have a full time job, so while I'd be open to taking a retainer to be available for immediate work, the fee that I would charge for such a contract is absurd. Basically more than my full-time employment.
There's lots of cloudformation, CDK, terraform scripts open sourced, but they're a nightmare.
The script itself is probably 20-30% of the time, 70% is learning the underlying system/technology. Once you've got the learning out of the way, the scripts start making things super easy/fast.
