Virtual or shared hosting is a technology where one server (dedicated or virtual) hosts many websites of different owners. Users share CPU, memory, and Internet connection resources.
Advantages:
You don't need to configure server settings - everything is already done by the hosting provider․
The server's operation is being monitored by the staff of the hosting provider, software is being updated, and errors fixed, hacker attacks are being monitored on the server side.
In case of hardware problems, backup equipment is turned on, and if necessary, you get access to your backups for recovery.
On shared hosting, you have access to a control panel that allows you to make various additional settings for your website
Well, the most important advantage is the affordable price.
Of course, there are also disadvantages:
A limited amount of resources that are distributed among all sites hosted on this server.
It is possible that one of the users will be included in the blacklist of spam senders, which may affect all users, although for a very short time as system administrators of the hosting company are taking measures to change email routes.
The limited software used in shared hosting is not a very big problem because all major programs and programming languages are being supported.
To summarize, we can state that for most small and medium-sized businesses, virtual hosting allows them to solve their problems of being represented on the Internet.
