1. هاست اشتراکی
2. سرورهای مجازی
3. سرور اختصاصی

نکته ای در مورد سرورهای اختصاصی و حتی گاها VPSها هست اینکه عموما پشتیبانی این‌ها توسط شما تامین می‌شود و  یا باید یک مدیر سرور با حق ماهیانه اختیار کنید یا در صورت بروز مشکل به صورت ساعتی حق حل مشکل را بدهید. بهتر هست این مورد را از قبل توسط میزبان جویا شوید.

1. دیتاسنتر
2. سرور
3. نزدیکی سرور به محل زندگی کاربران هدف
