MySQL is the most widely adopted open source relational database and serves as the primary relational data store for many popular websites, applications, and commercial products. With more than 20 years of community-backed development and support, MySQL is a reliable, stable, and secure SQL-based database management system. The MySQL database is suitable for a wide variety of use cases, including mission critical apps, dynamic websites, and as an embedded database for software, hardware, and appliances.

AWS supports MySQL in a variety of ways, including a fully managed database service, Amazon Relational Database Service (RDS) for MySQL. Amazon Aurora with MySQL compatibility is also built using MySQL, and Amazon RDS supports the popular MySQL fork project, MariaDB. You can also host MySQL on Amazon EC2 and self-manage the database, or browse the 3rd party MySQL offerings on AWS Marketplace.

History of MySQL

The first version of MySQL Server was released in 1995 by the Swedish company MySQL AB, founded by David Axmark, Allan Larsson, and Michael Widenius. MySQL takes its name from Widenius’ daughter, named My. The MySQL project was released as open source in 2000, under the GNU General Public License (GPL). By 2001, MySQL had reached more than 2 million active installations; by 2004, the software was being downloaded more than 30,000 times a day. MySQL was acquired by Sun Microsystems in 2008 and, when Oracle acquired Sun in 2009, it also took ownership of MySQL. Today, MySQL is the most widely used open source relational database system.

Benefits of using MySQL

Ease-of-use and performance

MySQL database has found favor with web developers due to its ease-of-use and productivity features, including triggers, stored procedures, and updatable views. MySQL includes utilities like mysqldump, a backup program; mysqladmin, an administrative client; and MySQL Workbench, a GUI for management and migration work.

Over time, MySQL has boosted its performance capabilities with features including B-tree disk tables with index compression, thread-based memory allocation, and optimized nested-loop joins. Row-level locking and consistent reads in the storage engine give MySQL additional performance benefits for multi-user concurrency.

Reliability and security

MySQL’s InnoDB transactional storage engine adheres to the ACID model, with capabilities that improve data protection, including point-in-time recovery and autocommit. InnoDB offers additional data integrity through support for foreign key constraints, preventing data inconsistencies across tables.

MySQL includes hardened and flexible security features, including host-based verification and encryption of password traffic. InnoDB offers additional security benefits, with data-at-rest tablespace encryption using a two-tier encryption key architecture.

Open source license

MySQL is available under an open source license (the GNU General Public License) allowing you to freely use and modify the source code. Managed versions of MySQL, like Amazon RDS for MySQL, carry no additional licensing costs.

MySQL’s large, global community of contributors and enthusiasts bring many additional and long-tail benefits to using the database system. For example, the MySQL community stays on top of security issues and bug fixes, contributing to the overall resilience of the software. MySQL user groups, events, forums, and mailing lists provide a built-in network for education and support.

General purpose OLTP database

MySQL is suitable for any application requiring a transactional SQL engine, including mission-critical apps and heavy trafficked websites. MySQL adheres to ACID principles and includes extensions to ANSI/ISO Standard SQL, as well as support for XML and JSON. MySQL also supports high-availability database clustering, and can handle terabyte-sized databases. Popular applications that use the MySQL database include TYPO3, MODx, Joomla, WordPress, phpBB, MyBB, and Drupal.

eCommerce applications

MySQL is one of the most popular transactional engines for eCommerce platforms. MySQL is particularly useful for managing customer data, transactions, and product catalogs. In eCommerce solutions, MySQL is often used in conjunction with other, non-relational databases, including document and key-value stores for syncing order data, and storing non-product data.

LAMP open source stack

MySQL is integral to countless applications running on the LAMP open source software stack (LAMP stands for Linux, Apache, MySQL, and PHP/Python/Perl). LAMP is a ubiquitous web services solution stack and is widely considered the platform of choice for dynamic websites and high-performance web applications.

MySQL fork projects

MariaDB

MariaDB is a popular fork of MySQL from MariaDB, which was founded by the original developers of MySQL who intended it to remain free and open source under the GNU GPL. While MariaDB is maintained separately from MySQL, it retains a high degree of MySQL compatibility, including library binary equivalency, and exact matching with APIs.

Percona Server

Percona Server is another popular fork of MySQL from Percona. Percona Server includes XtraDB, Percona’s fork of the InnoDB Storage Engine.

Language support

MySQL supports most leading programming languages and protocols, including:

Python

Java

Perl

Node.js

.Net

PHP

Ruby

Erlang

C/C++

Tcl

ODBC

Objective-C

MySQL vs. PostgreSQL

MySQL and PostgreSQL are both popular open source relational databases. Traditionally, MySQL has been perceived as easy to use and fast, whereas PostgreSQL has been perceived as feature-rich and more comparable to commercial databases like Oracle. However, the current major versions of MySQL and PostgreSQL both offer many robust features and capabilities in the way of performance, reliability, security, and more. You can learn more about PostgreSQL and try Amazon RDS for PostgreSQL using the AWS Free Tier.

MySQL Hosting Options on AWS

Self-managed MySQL on Amazon EC2

Historically, relational databases have been on-premises, and as database workloads moved to the cloud, organizations initially leveraged Amazon EC2 to run their own databases. With this approach, you have to manage all of the usual administration tasks that accompany an on-premises database such as hardware provisioning, database setup, tuning, patching, backups, and scaling.

Fully Managed MySQL on Amazon RDS

Amazon offers a fully managed relational database service, Amazon RDS for MySQL, available for trial at no cost with the AWS Free Tier. Amazon RDS makes it easy to set up, operate, and scale MySQL deployments in the cloud. With Amazon RDS, you can deploy internet-scale MySQL deployments in minutes, with cost-efficient and resizable hardware capacity.

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

  • Write when the problem started and how it changed.
  • Bring old prescriptions, investigation reports, and current medicines.
  • Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
  • Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

  • What is the most likely cause of my symptoms?
  • Which danger signs mean I should go to hospital quickly?
  • Which tests are necessary now, and which can wait?
  • How should I take medicines safely and what side effects should I watch for?
  • When should I come for follow-up?

Tests to discuss

  • Vital signs: temperature, pulse, blood pressure, oxygen saturation
  • Basic physical examination by a clinician
  • CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

  • Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
  • Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
  • Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

  • Rest, drink safe water, and observe symptoms carefully.
  • Keep a written note of symptoms, duration, temperature, medicines already taken, and allergy history.
  • Seek medical care quickly if symptoms are severe, worsening, or unusual for the patient.

OTC medicine safety

  • For mild pain or fever, ask a registered pharmacist or doctor before using common over-the-counter pain/fever medicines.
  • Do not combine multiple pain medicines without advice, especially if you have kidney disease, liver disease, stomach ulcer, asthma, pregnancy, or take blood thinners.
  • Do not give adult medicines to children unless a qualified clinician advises it.

Avoid these mistakes

  • Do not start antibiotics without a proper medical decision.
  • Do not use steroid tablets or injections casually for quick relief.
  • Do not delay emergency care because of home remedies.

Get urgent help if

For rural patients and family caregivers

Patient health record and symptom diary

Write your symptoms, medicines already taken, test results, and questions before visiting a doctor. This note stays on your device unless you print or copy it.

Doctor to discuss: Doctor / qualified healthcare provider
Tests to discuss with doctor
  • Basic vital signs: temperature, pulse, blood pressure, oxygen level if needed
  • Relevant blood, urine, imaging, or specialist tests only after clinical assessment
Questions to ask
  • What is the most likely cause of my symptoms?
  • Which warning signs mean I should go to emergency care?
  • Which tests are really needed now?
  • Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Safe pathway to proper treatment

Care roadmap for: What is MySQL?

Use this simple roadmap to understand the next safe steps. It is educational and does not replace examination by a doctor.

Go to emergency care if you notice:
  • Severe or rapidly worsening symptoms
  • Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration
Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.
  1. Step 1

    Check danger signs first

    If danger signs are present, seek emergency care and do not wait for online information.

  2. Step 2

    Record the symptom story

    Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.

  3. Step 3

    Visit a qualified clinician

    A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.

  4. Step 4

    Do only useful tests

    Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.

  5. Step 5

    Follow up and return early if worse

    If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips
  • Take a written symptom diary and all previous prescriptions/test reports.
  • Do not hide medicines already taken, even herbal or over-the-counter medicines.
  • Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
