MySQL Overview

MySQL from KakaoCloud is a fully managed Relational Database Management System (RDBMS) service based on the open-source MySQL Community Edition.
It allows you to easily provision MySQL instances through the console without complex installation or configuration processes, and it is designed for secure operation within a logically isolated VPC environment.

For detailed information about MySQL, refer to the official MySQL documentation.

Terminology
  • Relational Database: A database system that structures data in tables and uses SQL to define and manipulate data.
  • RDBMS (Relational Database Management System): Software for managing relational databases. Examples include MySQL, PostgreSQL, and Oracle.

Supported versions​

KakaoCloud MySQL is based on the open-source MySQL Community Edition version 8.0 and below.
The latest supported version is 8.0.41. For more details, refer to the MySQL 8 release notes.

Each version has different feature support and end-of-life (EOL) schedules.
Versions past EOL no longer receive security patches, so caution is advised.
For security-related details, refer to the official documentation.

Supported Engines and Versions
  • MySQL: 8.0.34, 8.0.41

Purpose and use cases​

MySQL is widely used as a reliable data store in various systems that require data integrity and a relational data model.
As an open-source solution, it supports a wide range of operating systems and programming languages, enabling flexible integration across applications.

When managing MySQL manually, you are responsible for tasks such as infrastructure setup, security patches, upgrades, and configuring clustering or replication for high availability.
Failure recovery also requires manual intervention, increasing operational overhead.

However, KakaoCloud’s MySQL service automates these complexities, allowing you to easily create and manage instances via the console.
It provides a more efficient environment for managing databases with features like backup and restore, automatic updates, and real-time monitoring.

With its lightweight architecture and fast performance, MySQL is ideal for web and mobile applications.
Its ease of installation and configuration makes it well-suited for early-stage services, and it performs effectively for read-heavy workloads such as user authentication, session management, and e-commerce.
It is especially beneficial in scenarios requiring real-time responses, such as startups, small-to-medium services, game servers, and IoT data collection.
