VPS hosting explained: when do you actually need it?
Shared hosting puts your site on a server alongside many others, splitting resources between all of them. A VPS (Virtual Private Server) instead gives you a dedicated slice of CPU, RAM and storage that's yours alone — with full root access to configure it however you like.
When to move up. If your site is outgrowing shared hosting — slow under traffic spikes, needs a specific software stack, or you simply want isolation from other tenants — a VPS is the next step up without jumping straight to a full dedicated server.
Performance vs. High Performance. Irist's Performance tier covers general-purpose workloads from a single 1 vCPU / 1 GB plan up to 16 vCPU / 32 GB. High Performance trades some vCPU count for more RAM per core, better suited to memory-hungry applications like databases or heavier caching layers. Every plan above the entry tier includes the option to add cPanel with unlimited accounts.
