Some thoughts against it:
Chatbots are a crowded market already.
Chatbots that are delivering value for a company are very product specific -> lot of training needed
As the customers seem not to understand the process of building a chatbot, it will be very difficult to find the 10-20% of whatever.
Selling cheap is not less tedious than selling high end.
To proof me wrong, just try to sell the idea as a not yet existent or as a fake product. Build a landing page where people can subscribe to get further information, lead a few prospects to this page and count the subscriptions.
Don‘t think too far into the future.
Check market fit first. If it‘s successfull decide very carefully between make and buy. I.e. There are several cloud service providers where small virtual machines start under 3$/month and some of them can be fully automated.
Have a look at scaleway.com. Nice API. Did Dome interesting stuff with it. For bigger projects it may be a good idea to have a dedicated server and play around with „virsh“ (KVM).
I used Scaleway and Hetzner so far. Both are good regarding GDPDR issues and both have well working APIs and can be integrated with Terraform. Hetzner starts at 2.99 €/month With the smallest virtual server.
I‘m afraid, there‘s no General solution.
There are multiple solutions for distributed systems like Ceph for file systems or diverse distributed databases.
But it all depends on the application.
Does ist really need Shared resources? I.e. Isn‘t a replicated DB sufficient ? Those are the questions to make.
The extremest solution is the one virtual server Fiats one customer approach (which i‘m building for a customer actally)
We ran short of paper in our Kniffel (well known dices game in germany) games in holiday. So i developed a digital version in around 8 hours. https://diesunddas.arachno.de/knoffel.php
