Have you wonder and asked yourselves in web hosting, why a shared hosting is cheaper? Many customers have thought they are the same. Basically, I need a website and a few email accounts. Well, you are not wrong. But a shared hosting vs a VPS there is differences. These reasons that I’m highlighting might affect you and your organization. So, it is good to read and to find out the differences.
Shared hosting or a VPS are still sharing a server. However, the shared methods are different. You put all the users into a server, they share mail service, web server, database server, Despite you can still restrict resources like memory to the budget buyers and hosting a website using an IP address. Actually, you are using the same IP address as the rest in the server. What’s wrong? That’s nothing wrong until someone email account is compromised and send spam emails. Ok, he is sending spam email, it has nothing to with me. Here comes the problem. Email servers have this basic anti-spam thingy known as RBL. RBLs are maintained by different agencies. The popular one like Spamhaus, SpamCop, Barracuda etc. These RBLs maintain a list of spammer through their system that detects spammer almost in real-time. So, if your email server IP is in the blacklist. Your recipient email will be rejected by their mail server. So, you are too affected because the RBLs blocked emails from your email servers IP address. Right, assign a dedicated IP will solve this problem. Yes, if the price has remained competitive. If the total price is the same as the entry VPS, it will not make sense. This is why;
VPS has allocated CPU units and RAM, unlike Shared Hosting. Even you said yes, my shared hosting plan has RAM. Yes, you are not wrong but it made a difference. Restricted and allocated has a different meaning here. Shared Hosting can use that amount of RAM but VPS is guaranteed which is the minimum memory you can consume. If there is memory available but not allocated you, in some virtualization you are allowed to burst and use more than what you have been allocated.
VPS is independent and unique, has its own operating and services. Others have difficulty with their web server for example. it will not affect you like the shared Hosting. Basically, those important services like web, email, database etc are isolated from one to another. Those reasons, you can accommodate more users in Shared Hosting solutions whereas VPS has a lower density in this area. Thus, Shared Hosting is cheaper for those reasons. Not forgetting, the control panel is shared by many in a shared server. It’s cheaper in control panel license as it is shared, whereas VPS control panel is per instance basis.
