Hi there!
Welcome to KNIME community!
In general the deployment topic is not the easiest one to understand and implement in a software but I believe KNIME covers this pretty well and offers various possibilities. I don’t think that the blog post you are referencing to is worthless at all. It can be a bit confusing as it explains different ways and methods in short time and covering both KNIME Analytics Platform and KNIME Server. From that perspective blog post can be improved for sure and your feedback will be taken into account.
Here is topic where I believe simple deployment it is explained pretty well. At least for me as I’m bit of a dummy regarding deployment
Hope it will help.
Not sure about paid support plans but feel free to send mail to sales@knime.com for more information.
Have a nice day,
Ivan
