MySQL 8.0 Secure, Optimized, and Future-Ready

MySQL has been at the core of nearly every system I’ve built, scaled, or architected over the last two decades from small applications to mission-critical enterprise platforms, multi-tenant SaaS products, and high-traffic production environments. This book is the result of that real journey: not theory, but lived experience outages, pressure tuning, performance optimization, complex migrations, and database designs that had to run flawlessly. MySQL 8.0 Secure, Optimized, and Future-Ready is a practical, structured, and modern guide to MySQL 8.0 written for developers, DBAs, DevOps teams, architects, data engineers, and students who want to replace outdated habits with today’s best practices. It explains MySQL with clarity and depth, without unnecessary complexity, and helps you build systems that are secure, scalable, and high-performance. Inside, you’ll learn how MySQL works internally, how to design clean schemas, and how to write modern SQL using CTEs, window functions, and JSON. You’ll also master indexing strategies, query optimization, server tuning, and real production troubleshooting using logs, metrics, and the Performance/Sys schema. Security is covered deeply SSL/TLS, roles, encryption, and hardening along with replication, clustering, backups, and high availability. The book also connects MySQL to the modern ecosystem: cloud platforms, analytics, ETL pipelines, BI tools, and real-world case studies. The book is organized into four progressive parts Foundation, Developer’s Core, Administration & High Availability, and the MySQL Ecosystem & Future so you can learn step by step, practice as you go, and confidently operate MySQL in real production environments.
