The better hosting for a forum or big site depends on several factors, including:
Traffic volume: You need a hosting that can handle high traffic volumes, especially during peak hours.
Scalability: Choose a hosting that can grow with your website, so you won't have to switch to another provider as your site grows.
Performance: You want a hosting that provides fast loading speeds, so your visitors won't get frustrated waiting for pages to load.
Reliability: Choose a hosting with a high uptime guarantee, so your site will be available for your visitors most of the time.
Support: Consider a hosting with good customer support, especially if you're not tech-savvy.
Based on these criteria, some of the most popular options for hosting big sites include cloud hosting, dedicated hosting, and managed WordPress hosting. It's always best to compare several providers and read reviews from other users before making a decision.
