WordPress reseller hosting gives every client their own isolated cPanel account and PHP-FPM pool — but only if the host runs CloudLinux CageFS and allocates per-account resources. Here is the infrastructure checklist for 2026.

WordPress email deliverability hosting failures almost always start with a shared IP address, not your plugin settings. A dedicated IP, correct reverse DNS, and SPF/DKIM/DMARC records fix the root cause. AHosting includes a dedicated IP on every WordPress plan at no extra cost.

WordPress VPS hosting gives your site guaranteed CPU, RAM, and SSD storage — the upgrade to consider when TTFB exceeds 600ms, traffic spikes crash your pages, PHP memory limits trigger repeatedly, WooCommerce checkout times out, or your host flags you for resource overuse. AHosting KVM VPS plans start at $8.79/month with a free dedicated IP included.

WordPress Multisite hosting requires wildcard DNS, adequate PHP workers, and a host that supports subdomain networks. Shared hosting works for small subdirectory networks but hits limits fast. At five or more active sites with real traffic, upgrade to a VPS — or switch to Reseller Hosting if you manage independent client sites that need full isolation.
