In this chapter, you understood a few things about MySQL's behavior with Zabbix.

What we need to keep in mind is that we need to know (or design) our environment and take into account the number of Zabbix users, the number of screens and maps created, the number of VPS necessary, the database disks (SSD, SAS, SATA, and so on), and the database's physical memory (for the innodb_buffer_pool_size configuration).

The more we know about the environment, the easier it will be to define the correct parameter of our MySQL.

We also talked about the reasons for choosing MySQL as the database for Zabbix and the main MySQL settings related to Zabbix's performance. In the next chapter, we'll talk about the Zabbix frontend and how this part can be handled for better performance.
