You have a certain hard disk space, an assigned CPU, a RAM memory and a monthly data transfer rate at your disposal. In a shared hosting, you only have FTP access to your account. There are all your folders in the root directory, but you do not have access to what is behind, you cannot enter the computer where your files are stored. But in a cheap vps hosting with high availability you can do it, just like in a dedicated server, only you do not have the number of resources that you would have in a dedicated server.
On the other hand, the VPS offers excellent scalability, since in any case, you have the possibility of adding more RAM, more CPU or your monthly transfer.
By being able to access the software, you also have the possibility to change the default configuration of Apache and implement the improvements you want.
With shared hosting, since there are other user accounts hosted on the same machine, there is not total independence. It can be an economical solution for you if your website does not require too many resources, but if you are starting to have high traffic needs, it is advisable that you leave the shared hosting and switch to a cheap VPS, where you enjoy exclusive resources.
What can you use a VPS for?

Can I use several VPS?
Some individuals and companies, instead of hiring a single VPS for a web page, prefer to have several cheap VPS. For example, to ensure the stability of the page, so that if in one case one of the servers does not work, the other is used.
Also to divide different parts of a website into different servers, achieving a better overall performance of the whole. For example, you can divide the application server, the web front, and the database into three different VPS so that they work faster and have better performance. This is advisable to do it, for example, when you have a very large and heavy database, as is the case with many online stores.
When do you not need a VPS?
We are going, to be honest with you; despite the many benefits of a VPS at iozoom.com, you do not necessarily need a virtual server and a cheaper option may suffice. The hosting sharing is a solution that is not necessarily bad; depends on the web project we are talking about, the size of the page and especially the amount of traffic that is currently supported.
If you have a blog or a web page and you still do not reach 1000 or 2000 visits per day, it is very likely that a good shared hosting is enough for you. Your project is still starting and you have not reached enough success to need to expand the space.
However, yes you have to take into account your growth forecasts; If you want to start directly with a VPS to save the change in the future, since you think you are going to grow a lot in the next months or you are going to do advertising campaigns that will bring you a lot of traffic, then yes that can be a good solution bet on a virtual server.
