If you want to host your web site then you have two choices.
1) Dedicated Web Hosting
2) Shared Web hosting
Dedicated web hosting is costly but you get a full control of your server. Shared hosting is cheap but you share CPU resources with many other web sites.
How Much Each Web Host Costs?
You can get dedicated website hosting at $100 to $200 per month charges. If you are just starting out your online business, this is very high amount.
You can get shared hosting at just $3 to $9 per month. Shared hosting is very cheap because all CPU resources are shared among many clients.
How Much Secure Each Hosting Is?
Well, dedicated website hosting is much more secure than shared web hosting. If any site on shared sever is hacked then it can affect other web sites too.
In dedicated website hosting, you have full access for your server. So that reduces the chances of being hacked due to other people’s mistake. Although if you have very bad luck then dedicated server can also be hacked but chances are less compared to shared web hosting.
Access Level
In shared website hosting, you can’t get full access of your server. In dedicated hosting, you have full access of your server. You can do whatever you like with dedicated hosting.
Getting full access to the server is beneficial as well as harmful also. You can mess up all setting by mistake if you have full access. You cannot do such stupid thing in shared web hosting.
I personally don’t like the dedicated hosting due to its price. I believe it’s not worth. I have seen many high traffic web sites on the shared hosting. So don’t assume that if you have high traffic then dedicated hosting is the only solution.
