MySQL
MySQL is an open-source relational database management system (RDBMS) that uses Structured Query Language (SQL) for managing and querying data. It is widely used for web applications, data warehousing, and e-commerce platforms due to its reliability, performance, and ease of use. Self-hosted MySQL refers to installing and running MySQL on your own servers or infrastructure, giving you full control over configuration, security, and maintenance.
Developers should learn self-hosted MySQL when they need full control over their database environment, such as for custom performance tuning, specific security requirements, or compliance with data residency laws. It is ideal for applications where data privacy, low latency, or integration with on-premises systems is critical, such as in enterprise software, financial services, or high-traffic websites. Self-hosting allows for tailored backups, scaling, and monitoring without reliance on third-party cloud providers.
