cPFence Yes, I get it and it's why, with all the positives you mentioned and more that I noticed, I want to run with Enhance so very much. It's too bad the developers didn't know the limitations of docker. That will be remedied once they get V12 out. I applauded them for taking the time to fix this and do it right!
With CentOS 7 I believe we had to start over to go to v8 with different servers. It's actually easy to go from let's say, Almalinux to 8 to 9 for example with the quick and easy Elevate/leap. I did that on all our cPanel servers last year and I had no issues at all. I'm betting that Almalinux 9 to 10 will be just as smooth.
I can say one thing at the moment, that is, I am now thinking to offer multiple shared hosting platforms since all this investigating into what to replace cPanel with. Let the customer choose! Of course, I'll have to make some nice comparisons of each, so it is not overwhelming and confusing to the customer to choose what is good for them. Well, that's one reason my customers stay with me. I walk them through anything they need.
I just bought an Enhance license and I am about to deploy the 1st kvm with it. I'm mainly testing and playing for now to see how it all works. I think the biggest issue for me is that if I start with Enhance on Ubuntu and then go live with some websites, it will be stuck with Ubuntu. I realize down the road in maybe 6 months; they will start supporting other distros OS like Almalinux. I can't wait anymore.
Maybe I will just start out with Enhance v11 and when V12 is released with the features I want and ability to run on Almalinux for example, I'll just create a separate Enhance cluster running v12 and the move any production websites over to it. Sounds like a plan!
Also, cPFence, you are the one that turned me back to even giving Enhance a try at this point. I have read nearly everything there is to read about Enhance including the forums at this site. I read almost everything your website as well. I think with your product added to Enhance; I'll have most of the features I am used to with CSF minus the port and Country stuff. The basic firewall of Ubuntu is fine to open and close ports as needed so I'm good for now.
I would like to thank you for the many explanations and help you have given to the fellow Enhance users, as it has helped me too already!
