VPS Hosting
VPS (Virtual Private Server) hosting partitions a physical server into isolated virtual machines using hypervisor technology, giving each tenant guaranteed CPU and RAM allocations. Unlike [[shared-hosting|shared hosting]], VPS tenants receive a dedicated IP address, enabling proper [[reverse-dns|reverse DNS]] configuration and improving transactional email deliverability. Root access allows custom software installation, [[ssl-tls|SSL certificate]] management, and fine-grained [[web-hosting|web server]] configuration. VPS plans are common for growing businesses that need predictable performance without the cost of a [[dedicated-server|dedicated server]].
Example
A SaaS startup on a $40/month VPS gets a dedicated IP (e.g., 203.0.113.5), configures PTR reverse DNS to mail.startup.com, and achieves 98%+ email inbox placement versus 85% on shared hosting.
