Hi guys,
Whilst i have been playing around with web hosting for some time, it has almost always been as a reseller. Most of my work has centered around building websites however I wish to move onto Google Cloud Platform and run my own cloud servers.
I realise that i have a lot of learning to do, however, I have been working hard on the steep learning curve and am now pretty much settled on using debian or ubuntu (i prefer ubuntu actually).

I am interested in some input into compatible hosting platforms that work best with whmcs.

I have looked at the following and am interested in your input on ease of module installation, functionality, regular updates, support. I have noticed that some of the programs in the list below are either not that stable when i have set them up on Google Cloud or the whmcs modules seem to be very demanding to install and configure.

If i had the money i think i would simply go for a one platform solution for both billing and server management...perhaps in the future? (although i am playing around trying to get ISP systems up and running on Google Cloud Platform)

ISP Systems
Centos Web Panel (havent tried this one yet but am about too)

any others that you think are well worth my considering.

Obviously i have not included plesk and whm cpanel (already know that those two work well with whmcs)
