8.2.1. General information about MySQL

MySQL is relational database management system. MySQL is available on hosting in two variants: as a part of shared or business hosting service and as a standalone service.

Advantages of MySQL as a standalone service:

• Compared to shared hosting:
  • No limits on the number of tables, the size of one database and the total size of all databases, as on shared hosting.
  • No limit on the number of CPU minutes.
• Compared to business hosting:
  • You can configure access restrictions for individual IP addresses.
  • Using a standalone MySQL service will free up business hosting resources to run scripts (on business hosting, resources are shared between the web server and MySQL).
• Any database names and usernames can be used, without the mandatory prefix.
• Replication is available.

MySQL 8.4 is used.

Available plans differ:

• Number of available processor cores.
• Amount of RAM.
• Capacity of disk space.

While using MySQL plan can be changed.

In order for a site on hosting to connect to the database in an instance, that site must have installed PHP version 7.4 or higher (see official PHP documentation).
