      @scottalanmiller no, that's because there aren't any LXC-based VPS hosting solutions out there 🙂 Even OVZ is more common

        Most, but Windows is a taint here. Any Windows means you need KVM. Even if only one out of thousands of workloads. Unless you want different solutions for different workloads, which a lot of places want to avoid.

        A cloud provider can potentially create a system where if you pick Linux you get a container and if you pick Windows you get a VM, sure. But that's not how this is done today. Most cloud providers don't even touch containers outside a container specific system, like AKS/GKE (or the old school VPS based on Parallels/OVZ). Instead they simply give you a choice of guest OS and instance type, and you always get a proper VM.

        Right, because they want a single system to maintain rather than two. It makes sense. But that's my point...

        People almost always want...

        1. A single platform.
        2. The option for Windows.

          Because they want to support Windows. Either already do, or are prepared for the future.

            HostFav does LXC for their cloud, with a KVM option. They still want to support Windows, but were willing to give in on the "single platform" option.

              @scottalanmiller well, in any case - that's where you get KVM from most providers. You want docker - you either deploy your own on cloud VMs or use GKE or whatever. I've never even seen LXC as an option

                Right, but of course you don't. I keep explaining why you don't and won't see it. But you keep responding with the result being exactly what I said.

                  And why do many of us choose Vultr? Because it provides a Windows option is a major reason. Sure the price is great and the reliability is great, but not having to have a different provider for different things is a major driver too. Even if we only have one Windows workload out of however many other things, it only takes one.

                    @scottalanmiller never even heard of HostFav, there are tons of small time providers out there, can't really cover them all.

                      Right, but the BIG providers all support Windows. It's needed to be a big player.

                        @scottalanmiller I don't use Vultr, so speak for yourself:) I also don't use Windows. But I use a lot of Linux on AWS and GCP as well as some openstack platforms. for me what is important isn't the ability to run Windows but the ability to run a proper OS and not a container, plus the more interesting instance types, like the i3.metal.

                          But big players require the ability to run Windows. You want big player features. You are just explaining back why it is a taint that affects you even when you don't recognize it. Only small players are LXC or OpenVZ only... since they can't service the vast majority of customers, even customers that are almost entirely Linux.

                            @scottalanmiller the really big providers also don't care about the cost of adding a feature like I mentioned earlier (if linux deploy on container, else deploy on VM), but they still default to VMs, despite the potential of such a feature to save them money due to better density and resource utilization

                              If they don't care to do so, why do you feel that that is given that you feel it would make them money? That sounds like they simply don't want to make money.

                                @scottalanmiller my take is that they don't really see it as a huge advantage. And they recognize customers like me, who need to run a proper OS and not a container. They also don't really care about what OS that will be.

                                To put it in agile task terms: as a user, I want to be able to run an OS and perform actions the same way as if I'd be doing that on real hardware. As a developer, want to develop a product that works on my test machines, and then deploy on AWS or GCP without surprises. As a developer I want to develop in the cloud, and know that my code will work on my clients' machines properly.

                                So this is not really about windows, this is about providing a proper guest and not a husk like a docker runtime.

                                    What issue are you seeing with full container virtualization for your workloads? You are modifying the kernels?

                                          That seems like a pretty minor effort for someone like Amazon.

                                          However, with Firecracker, that's kind of what they are doing anyway.
