The choice of hosting should be based on a number of key points. First, the type of site. Shared hosting is suitable for small business card sites and blogs due to low expected loads. If you have a large project, a news portal or an online store, the only working option is a dedicated server.
Secondly, the number of sites. Virtually all virtual hostings have a limit on the number of simultaneously connected sites. In practice, this means the impossibility of running a large number of sites at the same time. There is no limit on the number of sites on dedicated servers.
Third, the expected number of users. The more people visit the site and use it, the more server resources are consumed. To ensure smooth operation of the site in conditions of peak loads, choose a dedicated server.
Finally, PO. Popular engines are popular because they are easy to run in shared hosting. For self-written CMS or less common technologies, a virtual or dedicated server is suitable.
