There are several differences between the VPS and shared hosting. 

Resources 

The first difference is the server resources. With the shared hosting, you are going to be sharing some of your resources. Therefore, you are going to have some limitations. This means that your website is not going to be able to use the resources beyond the maximum allowed. With the VPS hosting, you are going to have a lot more space on your website. This is because you are going to have more resources available to you. This is something that you are going to need if you want to expand your business. 

Performance 

The second difference is the performance of the system. With the shared hosting, there are other websites that are going to affect the performance of your website. When your performance is limited but maintenance is a lot easier, then you will be able to get more out of your return on investment. With VPS hosting, you are going to be able to get a better performance out of your website. But you are going to need to make sure that you have a system administrator so that your server is always going to run smoothly. 

Security 

The third difference is the security of your website. With the shared hosting, your website is still going to be safe but there is a chance that there could be a breach in the security. This could be because of the technical difficulties of the website. With the VPS hosting, you are going to have a lot more features as far as security goes with your system. This is going to be especially true if you have the budget to implement the customer support services that you are going to need to protect all of personal data. 

Pricing 

The fourth difference is the price that you are going to pay for the services. With the shared hosting, since you are going to be sharing a lot of the things that you are doing, then this is going to be a cheaper option. Therefore, if your website only need to work with the standard functionality, you can choose this option. With the VPS hosting, since you are going to be paying more for these services, you will be able to get more services for your money. This means that you will be able to increase the online services of the business. 

Administration 

The fifth difference is the server administration. With the shared hosting, you are not going to need a lot of maintenance to your service on your end. This means that you will get the basic services without any additional costs to you. If you don’t need a system administrator, then this is going to be a big plus. With the VPS hosting, since the website is going to be more complex, then you are going to need someone to focus on maintaining the server. This means that you will be able to customize your website more and configure all of your applications into the website.
