Years ago, if you wanted a server, you rented a dedicated server: one physical machine running one operating system. Virtualization changed that. A hypervisor runs on the physical server and creates virtual machines, each with its own OS, CPU, RAM, and disk. Each virtual machine thinks it’s on its own hardware. That’s VPS hosting.
How our hypervisors work
Our hypervisors use dual Intel CPUs (40+ cores with hyperthreading), 512 GB to over 1 TB of RAM, and dual 10G or 40G network interfaces, all on Supermicro hardware. We use KVM (Kernel-based Virtual Machine) as our virtualization layer, which is built into the Linux kernel and used by many of the world’s largest hosting platforms.
Each VPS gets its own allocation of vCPUs, RAM, and SSD storage. We don’t oversubscribe, so the resources you pay for are actually available to your virtual server.
Why VPS hosting is popular
Cost: A VPS can start at a few dollars a month because many virtual servers share one physical host. Each one uses a fraction of the hardware cost.
Flexibility: You can resize your VPS (more RAM, more CPU) without migrating to new hardware. Scale up when you need it, scale down when you don’t.
Isolation: Unlike shared hosting, your VPS runs in its own virtual machine with its own OS. Other tenants can’t access your files or affect your performance.
Resilience: Our VPS disks are stored on Ceph (distributed SSD storage), so if a hypervisor fails, your virtual server can be started on another host without data loss.
VPS vs cloud vs dedicated
VPS, virtual machine, virtual server, cloud server, virtual dedicated server: these terms all describe the same thing. “The cloud” just means your servers run in a provider’s data center instead of your office. A dedicated server is the opposite end: you get the entire physical machine, no sharing.
We offer both VPS hosting (starting at a few dollars/month) and dedicated servers (for workloads that need bare metal). Sign up to try a virtual server, or contact us to discuss your needs.
