VPS vs. Shared Hosting
ARPHost Virtual Private Servers deliver the perfect balance of performance, flexibility, and cost-effectiveness. Built on KVM (Kernel-based Virtual Machine) technology, each VPS provides true hardware virtualization with dedicated CPU cores, guaranteed RAM, and isolated storage resources.
Unlike container-based solutions that share a kernel with other users, our KVM VPS instances run their own complete operating system with full root access. This means you can install any software, configure custom kernels, and run virtually any application without restrictions.
Every VPS is powered by enterprise NVMe SSD storage for exceptional I/O performance, and connected to our redundant network with multiple Tier-1 providers. Whether you need a development environment, production web server, or database backend, our virtual servers scale to meet your needs.
VPS vs. Shared Hosting
Shared hosting places multiple websites on a single server, sharing CPU, memory, and storage among all users. While economical, this leads to unpredictable performance and security concerns. VPS hosting provides dedicated resources in an isolated environment, ensuring consistent performance and better security isolation.
KVM vs. OpenVZ
There are two primary virtualization technologies used for VPS hosting: KVM and OpenVZ. ARPHost exclusively uses KVM for several important reasons:
True Isolation: KVM creates fully isolated virtual machines with their own kernel, while OpenVZ containers share the host kernel. This means KVM VPS can run any operating system, not just Linux, and provides better security isolation.
Guaranteed Resources: KVM allocates dedicated CPU and RAM that cannot be “borrowed” by other VPS instances. OpenVZ often oversells resources, leading to performance degradation during peak usage.
Custom Kernels: With KVM, you can upgrade, modify, or replace your OS kernel. OpenVZ restricts you to the host’s kernel version and configuration.
Choosing the Right VPS Plan
When selecting a VPS plan, consider your application’s resource requirements. CPU cores handle threads of execution – multi-threaded applications benefit from more cores. RAM determines how much data your applications can work with simultaneously. Storage capacity and I/O speed affect how quickly data can be read and written.
Security Best Practices
While your VPS is isolated from other users, you’re responsible for securing your own instance. We recommend: keeping your OS and software updated, using strong passwords and SSH keys, configuring a firewall (iptables/nftables), and enabling automatic security updates for critical packages.
