VPS: VPS vs Shared
Shared Hosting and VPS are the two most commonly used hosting types. The key difference is resource allocation: Shared splits all resources with others; VPS provides isolated, dedicated resources for consistent performance.
Shared Hosting
Shared Hosting places hundreds to thousands of websites on one server using virtual hosting to separate them by domain name — but all resources are shared. If a neighbor consumes excessive CPU, you're affected (Noisy Neighbor Problem).
VPS: VPS Hosting
VPS uses Virtualization (Hypervisor like KVM) to split a physical server into isolated Virtual Machines, each with dedicated CPU, RAM, and storage. Operations are independent — neighbors' resource usage doesn't affect you.
Performance: VPS vs Shared
VPS performance is significantly better and more consistent than Shared Hosting because resources aren't shared. VPS load times are typically 2-10x lower, especially during peak traffic when Shared Hosting noticeably slows down.
Security: VPS vs Shared
VPS is far more secure than Shared Hosting due to complete isolation. On Shared Hosting, if another site on your server is compromised, malware can spread to you. VPS instances are completely isolated and you control all security settings.
VPS vs Shared Hosting Pricing
Shared Hosting costs significantly less than VPS. Entry Shared starts at 50-200 THB/month while entry VPS starts at 300-500 THB/month. Business-grade VPS with sufficient specs typically costs 1,000-3,000 THB/month.
Overview
Shared Hosting is much easier — providers handle everything and you manage via Control Panel. VPS requires Linux Server Administration knowledge, or you can opt for Managed VPS where support teams handle server management.
Choosing: Shared Hosting
Choose Shared Hosting when: just starting out, budget is limited, traffic is low (under 30,000 visits/month), you lack server knowledge, and you don't need custom software.
Choosing: VPS
Choose VPS when: traffic outgrows Shared limits, you need custom software or frameworks, running e-commerce requiring high reliability, or needing a dedicated IP for email deliverability.
