Workload Sizing Recommendation

Websites with < 50,000 monthly page views and static caching can operate reliably on high-performance NVMe shared hosting. High-traffic ecommerce and SaaS portals requiring background workers and Redis queues require dedicated KVM VPS or bare-metal hardware.

  • Shared Web Hosting ($3 – $10/mo): Multi-tenant cPanel environments with CloudLinux LVE limits (1 CPU core, 1GB RAM, 20 entry processes).
  • Cloud VPS ($10 – $80/mo): Dedicated virtual CPU cores, guaranteed NVMe storage, and root SSH access for custom Nginx/PHP-FPM stacks.
  • Bare-Metal Dedicated Servers ($100 – $500+/mo): 100% physical hardware isolation, dual redundant 10Gbps uplinks, and zero hypervisor overhead.
