Azure SQL vs MySQL

The advancement in the world of Cloud Computing over the last decade or so has been nothing short of astounding. This development pioneered the concept of cloud-hosted databases, among other things. In essence, these are cloud-based databases. Space and maintenance issues, for example, are no longer an issue with hosted databases. The cloud provider abstracts and manages these. This allows you to store virtually limitless amounts of data without having to worry about database maintenance.

The goal of this section is to compare one of these databases, the Azure SQL Database, which is hosted on the Microsoft Azure cloud platform, to MySQL. The most widely used open-source database management system (DBMS) today.

  • Architecture: Both Azure SQL Database and MySQL are relational database management systems that use SQL as their query language. Their architectures, however, are vastly different. MySQL stands for “MySQL Database Management System.” This refers to software that is used to define, manipulate, retrieve, and manage data in a database. It is not a database in and of itself; rather, it controls how data is stored and manipulated in a database. Its open-source nature, on the other hand, allows for a wide range of integration possibilities. MySQL DBMS software can be downloaded for free from the internet. It can then be used as-is or modified to suit the technology of your underlying system without sacrificing much performance.
    • MySQL: As a result, MySQL is extremely popular because it is both compatible and simple to set up. It runs on all major operating systems and supports all major programming languages. However, the GNU General Public License governs this flexibility (General Public License). This is how MySQL manages how its software is used. If you want to use MySQL in an environment that isn’t covered by this license, you can buy a commercial license from MySQL.
    • Azure SQL: The Azure SQL Database, on the other hand, is a database as a service. It’s a managed database that’s intelligent, scalable, and hosted in the cloud. Simply put, a database as a service (DBaaS) is a service that gives users on-demand access to a database. This can be done without the need for any physical hardware, software installation, or performance configuration. The service provider, in this case, Microsoft, is responsible for all administrative tasks and maintenance. The database is all that is required of the application owner or user. Because the Azure SQL database is part of the Azure cloud, it comes with a number of powerful features out of the box.
  • Strengths and Weaknesses:
    • MySQL: Because MySQL is open-source software, it has a lot of flexibility. Anyone can download and install MySQL for free and with very little effort from the internet. You can study its source code and customize its functionality to better suit your personal needs if it suits you better, as long as you stay within the constraints outlined in the governing software license. This is extremely powerful because you can have an effective database solution tailored to your application for a very low cost.

MySQL also has Connectors, which are essentially drivers and API libraries that you use to connect applications written in different programming languages to MySQL database servers running on the same machine or across the network. Connectors are available for almost all of today’s popular programming languages, with extensive documentation on how to use them.

MySQL also has a large user base due to its widespread popularity (MySQL ranks second among all database engines on the market according to db-engines) and maturity. As a result, there are a plethora of articles on the internet for just about any MySQL problem you can think of. If the Open Source way of life isn’t for you, MySQL also comes in an Enterprise and Cloud version. It’s called MySQL Cloud Service, and it’s powered by Oracle Cloud and built on MySQL Enterprise Edition.

If an application is developed locally and not for commercial purposes, MySQL can be used for free. Commercial use necessitates the purchase of a license, making it pricier than Azure SQL.

  • Azure SQL: The Azure SQL Database is a fantastic database as well. Because the SQL Database is part of the Azure ecosystem, it includes some extremely powerful features. From built-in machine learning and AI to advanced data security by default to automatic and configurable scalability that allows you to grow your database based on demand, with a pricing system that allows you to only pay for what you use. All of these features, as well as many others, are available to you as soon as you begin using the database; no additional installations are required.

You can also use the Azure SQL Database to create on-premise databases while still utilizing the Azure cloud’s capabilities. And, if your application stack is hosted on Azure, storing and retrieving data from your applications into the SQL database is a breeze, and leveraging all of the SQL database’s niceties to manipulate your data and optimize your queries improves the application performance even more.

However, because hosted databases are still in their infancy compared to established solutions like MySQL, hosted databases like the Azure SQL database aren’t used as frequently as older systems like MySQL, because users are still figuring out how to use the cloud. The SQL database, on the other hand, has extensive documentation and comprehensive training courses if you’re having trouble finding helpful resources online for debugging purposes.

Because Azure SQL can take advantage of the entire Azure platform to provide more meaningful ways to interact with data at a lower cost than MySQL, the likelihood that everyone will switch to Azure SQL is very high.

What are the Components of Azure MySQL Databases?

The Azure Database for MySQL consist of the following components:

Azure MySQL Components: MySQL Database Server

Azure Database for MySQL can offer high security, resource protection, fast restart functionality, and isolation for your database servers. These features are critical for performing scaling and restoring database servers in the event of a system failure. 

Generally, the data stored in your database server changes when a transaction is carried out at the server. Azure storage logs all such changes synchronously using the write logs (ib_log) function. Moreover, Data Pages present in Azure Database are also backed up into memory during checkpointing.

Azure MySQL Components: Remote Storage

The Azure storage is built with the aim of saving 3 copies of data from a region to facilitate Data availability & reliability. Therefore, the physical data files and log files of MySQL are stored in Azure Storage. Another advantage of Azure storage is that it is not dependent on the database server. In case of server failure, you can disconnect the Azure storage and reconnect it to a working server within a minute. Furthermore, this storage monitors storage errors regularly. If any corrupt data block is found, it automatically resolves the issue by instantiating a new archive copy.

Azure MySQL Components: Azure Application Gateway

Azure Application Gateway is a database proxy with the responsibility of routing the various client connections to the MySQL Database Server. A bunch of compute nodes (stateless) working under an IP address host the Gateway service. Any new client trying to establish contact with the Azure database for the MySQL server will reach this IP address first. The hardware responsible for hosting the Gateway is updated periodically. This ensures that users get a safe and efficient experience.

What are the Key Features of Azure MySQL Databases?
