HostGator gained points for uptime monitoring and regular backups, along with free cPanel or Plesk. We liked that SSH is available for the more technically inclined site operators and that dedicated IP addresses could be purchased. We did take points off because it's sometimes difficult to tell what the price is once promotional plans run their course. That said, with a generous 45-day money back guarantee, there's a hosting solution for almost everyone at HostGator.
VPS hosting sits in the intersection of shared hosting and dedicated servers. Unlike shared hosting, VPS is an isolated environment with dedicated resources, which means you have more processing power and your site loads faster. VPS is best suited for applications that have seasonal traffic spikes or RAM-heavy/CPU-intensive applications. If you are developing a new application that has a complex database and you’re not sure how many visits you’ll get, VPS hosting is the affordable option to start with before you upgrade to a dedicated server.

For many customers, possibly the most influential variable in evaluating a hosting service is cost. Cost can drive conversion, but cost can also cause you to make regrettable purchasing decisions. Don’t assume the cheapest option you can find is the best. Low cost can also mean low value, but not with the affordable hosts atop our recommendations list.
You could think of the sites that share your server as your roommates; there's really not that much separating you from them. Sure, you can close the bedroom door, but they can still cause nightmares for you in the kitchen and the bathroom. In web hosting terms, all the sites share a single server's resources, so huge traffic spike on Site A may impact the neighboring sites' performances. It's even possible that another site could take down the shared server altogether, if it crashed hard enough.

Factors that impact overall performance and speed are the allocated CPU resources and memory each account gets, how many websites a host allows per server, how their server stack looks with regards to PHP (PHP 7+ is a must these days), server-side caching, and more (have a look at our SiteGround vs HostGator comparison for an example of how much loading times can differ when you have a proper server config). The terminology might be a bit too technical, but the main things to look for would be CPU and memory resource allocation + allowed domains per server.
We use this analogy on our web hosting page. Shared hosting is like an apartment building – lots of residents in the same building, sharing the same resources, but also very affordable. Dedicated servers are like having your state-of-the-art house, where you’ll pay a lot more, but you also don’t have to share the space or utilities with anyone. VPS is in the middle, like a townhouse, where you have a few residents in the same building, but you each have dedicated resources and are in full control of your home. It costs less than a dedicated server, but still gives you much of the same benefits.
