You should poke around at the history behind Plesk, it might make more sense. Around 2003, a company named SWSoft bought Parallels and some other companies that specialized in control panels and server virtualization. Plesk tends to sell into corporate America, while cPanel is used by smaller companies. In 2008, SWSoft changed their name to Parallels. They competed with VMWare. In 2015, Parallels spun off Virtuozzo (a virtualization platform) and Plesk (that runs on Virtuozzo) into a separate entity, then sold it off to to Oakley Capital. In 2018, Oakley Capital acquired cPanel, Plesk’s largest competitor. In 2018, Corel (of CorelDraw fame) bought Parallels. In 2019, a private equity firm KKR acquired Corel, including Parallels. In late 2023, Broadcom acquired VMWare. Broadcom is an OEM, they don’t really deal with consumers. This is when they made VMWare Desktop and Fusion free. There’s some talk that KKR (who owns Parallels) might be purchasing Broadcom’s VMWare End User Compute (EUC) business. It’s all about VIRTUALIZATION. And it’s looking like KKR is going to end up owning EVERYTHING: Parallels and Virtuozzo, VMWare, Plesk, cPanel, and a bunch of related products that had been previously acquired under prior ownership and came along for the ride. Why do you suppose there’s so much musical chairs going on over the past 25 years and now one company owns all of them? The web server and hosting business started out as companies with a bunch of PCs in a room plugged into a WAN feed. They started building out larger and larger facilities to house more and more PC boxes. As the demand grew, companies started building rackable units to make them more compact. first 3U, then 2U, then 1U, then “blades” that fit 10 inside of one 3U box. Then CPUs got multiple processors in them and the price of memory and storage plummeted, and it became more economical to set up clusters of boxes with some virtualization software allowing you to spec out so many CPU cores, so much RAM, and so much disk space. Amazon got into the game and virtualized everything. Then IBM, Intel, Microsoft, Google, and others. Companies like Rackspace stopped upgrading their physical machines and started reselling virtual machines from Amazon and others. Today, I sort of doubt that there are many places like Rackspace left who have a big building with their own hardware in it. It’s just as profitable, if not mores, to simply resell resources from Amazon. So while Plesk and cPanel originated as a way of helping monetize shared servers by managing user accounts, if the hardware is replaced with AWS accounts, who’s going to notice? Virtuozzo was designed to support virtualization for Plesk; VMWare entire existnce is built around virtualization; and Parallels does the same thing. Althought I’d never given it much thought, it makes perfect sense for something like Plesk or cPanel/WHM to act as a wrapper for an AWS-based server that can be scaled up or down as needed. The Good News is that your machine resources are no longer capped-out by the physical limitations of the machine (or cluster) you’re running on — with AWS or Azure providing the VMs, you can dial-up as big of a machine as you can imagine. Makes perfect sense to me. I’m just trying to figure out why you’d be wanting to host Plesk on your own machine? You know you can run Webmin on AWS servers, right? I like cPanel and find it far easier to work with than Webmin; it also supports far more features. I used to use Plesk before cPanel, and I really loved it as well. But TBH, while it’s easy to SEE that most hosting vendors price their offerings based on things like #CPU Cores, #GB of RAM, #GB of SSD, internet traffic, etc., they could all be reselling stuff from AWS or Azure and delivering cPanel or Plesk as an option. -David Schwartz > On Feb 18, 2025, at 5:25 PM, Keith Smith via PLUG-discuss wrote: > > Hi, > > I have a win10 laptop that has VirtualBox installed on it and on VirtualBox I have a LAMP "Shared Hosting" configuration. > > This is on a private IP.
