Shared hosting is the least expensive option when it comes to finding a home for your website. As its name implies, with shared hosting you are sharing a server with multiple other sites, though no one can see what the others have on it. Shared hosting is ideal for small, low-traffic personal sites or static, single-page sites.
VPS (Virtual Private Server) hosting provides you with much greater security and performance over shared hosting with the added benefit of scalability. Instead of sharing a server, each VPS is its own separate virtual environment, complete with its own resources, operating system and software. VPS hosting is a powerful but economical choice for larger personal sites, startups and smaller businesses.
