What is VPS and VPN - Difference between VPS and VPN

VPS (Virtual Private Server)

A Virtual Private Server is a place where you host your websites. To make it simple, it is big server (dedicated server) that is separated in multiple smaller virtual server (thanks to virtualization technologies). We are rent those places. It is totally hosting related.

Basic hosting plan are shared server: you can only host files, and run some cron jobs. We won't install any specific program. We just provide basic hosting related stuff: perl, php, etc.

Then you have VPS which are "better, faster and stronger" than shared hosting. When you rent a VPS, you can install ANYTHING (as along as you respect TOS or are not caught) you want into it. You are provided with a SSH access. This SSH access allows you to manage your system via command line. You are root, which means you can do anything on the VPS. You can install any software, create any script, you can even break it. However since VPS are part of a bigger server, you don't own the full hardware for yourself. You share the hardware with other customer and get only a defined part of resources (lets say 1024mb ram, 2ghz CPU, 100mbtis bandwidth). You have what you pay for.

Finally, there are dedicated server. Like a VPS you have a SSH root access, and can do anything you like with your server. However this fime you don't share the hardware. You rent the full computer and you are sure to get what you paid for. It is of course more expensive, but it is way better if you need a heavy box.

VPN (Virtual Private Network)

A Virtual Private Network is a way to browse internet without revealing your IP address, hence anonymously. Technically, your computer (or router, see ddwrt on google) connects to an remote PC with an encrypted connection (allways use openVPN, and flee pptp vpn). Then this remote computer (the VPN) browse the web, pull your email, scrapes stuff, with his own IP.

This process is totally transparent for the end user (it only adds a few ms of latency and decrease your connection by very small amount due to encryption) and allows you a total anonymity on internet. In some point, this is better than proxies, because whatever you do, you are allways behind the VPN, whatever the port or the application is, with no setup, you are protected!

However, if you go scraping, or mass commenting, you wand to prefer multiple proxies. Multiple proxies = multiple IP,a nd proxies are like napkins. Use them, once they are busted / blacklisted, change them! The VPN only has one IP for all the customers... once you blacklist it, you have to find a new VPN provider.
