Shared – Shared resources: RAM, Disk Space, CPU
VPS – Dedicated RAM & Disk Space, Shared CPU
Dedicated – Your machine and only your machine
From the idea of networking the idea of the internet started and after three decades
web hosting services came in. Majority sites choosed VPS hosting among the three types.Why? What does VPS have/offer that shared hosting doesn't ?
Server level customization (just like on a dedicated)
Burstable memory – reserve resources, a la cloud computing/hosting – resources available when needed, idle or in use by another when not needed. Good for unexpected traffic spikes (the Digg effect).
Scalability – Can start small (1 site, no databases, etc) and grow (many sites, large Dbs, e-commerce, etc) without changing machines/upgrading.
With so many advantage VPS has, it becomes beneficial to majority of the sites
with multiple, large databases (i.e. product catalogs, etc); high traffic; multiple sites; sites with dynamic content; growing site; etc...but not enough of above for a dedicated server.
And not only that it is also a perfect middle ground between a shared platform and a dedicated server.
