A Content Distribution Network (CDN) is a network of servers distributed geographically. The purpose of a CDN is to deliver content on the internet much faster. If a user in Toronto is trying to access your website, the closest server to them will take care of this. But someone coming to your website from Sydney, Australia, will be catered to by a server closest to them. The main host server holds your website content, and all the other servers have a cached version each.
CloudLinux helps protect websites in a shared website hosting environment. If one of the websites on the servers gets attacked or gets a sudden growth in popularity and a lot of unexpected traffic, it will start draining all of the server resources, affecting other websites. CloudLinux makes sure this doesn’t happen. It will either slow down the website to stop it from hogging all resources or it will temporarily shut it down.
Before we launch into our buying guide, you should know the three different categories on offer: shared web hosting (a good basic option if you're on a budget), VPS hosting (more flexible) and dedicated servers (for those running a bigger operation and in need of something more capable). If you're not sure which is the best level for you, you’ll find a detailed explanation of the different tiers at the bottom of this guide. It's also worth bearing in mind that you need to pick something that's going to be able to grow and scale up with you.
