The answer is that there is no better solution than the other but it is essential to take into account the needs of each one, as simple as this!
Firstly, you need to know what is a shared hosting?
A shared hosting is a reserved space, a personal plot, within a server shared by several users. This server is capable of hosting several websites at the same time by subdividing its space or hosting capacity into smaller spaces, where each of the hosted websites resides.
To put a very simple simile, it is as if the server were a block of flats. In this case the floors would be the hosting spaces that house the people who live in it. These people share a common space and resources, in the same way that the owners of Linux or Windows hosting e a shared hosting share server resources with other users (disk space, CPU, RAM, monthly transfer, bandwidth, IP, etc.)
Shared web hosting is a useful solution for those who do not know or do not want to manage a dedicated server, which requires having advanced knowledge of server management. Another advantage of shared hosting that must not be forgotten is that its cost is much lower , since the available space is smaller and the machine is shared with other users. On the other hand, the provider of the hosting will be responsible for ensuring maximum security of the server and make backup copies of it, so that the user of the shared hosting can be quiet about the security of your space. Another advantage of shared hosting is that it is easily scalable, so that if a user subsequently needs to expand the capacity of their hosting, they can easily hire a superior web hosting plan.
Despite all these advantages of shared hosting, more advanced users or with larger projects are undoubtedly decided by dedicated hosting, that is, by having and managing their own server.
Naturally, having a server for exclusive use guarantees greater autonomy in the administration of a website and have the capacity to host multiple websites or even create a testing environment to build our project little by little and put it online when it is completed. Dedicated hosting, in addition, is the ideal solution for those who need to configure the server in their own way or want to develop applications in languages not supported by shared hostings ( Java or Python type).
Shared or dedicated hosting
It is also the right solution for those who need to have all the bandwidth to support a lot of traffic without the operation of the server being affected by it. An own server also has its own IP, while shared hosting users will also share the IP address.
In short, if we have several projects underway, it will surely be cheaper to hire a dedicated server to host all our projects that do not hire several shared hostings.
So, once again, depending on your needs of each one and the size of their projects, one solution will be cheaper than the other.
