Master-Slave Database Architecture

"Data is the new Oil", with rising Data - The accessibility, readability, and backup of the data are major concerns.

What is Master-Slave Database Configuration?

Master-Slave Database Configuration in simple words is dividing our master databases into multiple slave databases. The Slave database serves as a backup for the master database.

The master database is the primary storage of the data, where all the writing operations of the data request are performed whereas the reading operation is spread across multiple slave databases relative to the master database. This enhances the reliability of the databases to a great extent.

While developing applications at scale, you need two data resources - one to handle the write operations and the other one to handle the read operations. And that is where the master-slave database comes into the picture.

Benefits of Master-Slave database -

Let's say in a nightmare your Production server goes down. After a little debugging, you find out that it is due to the read/write requests to your database server.

In such cases, opting for a master-slave database architecture is recommended. Distributing load across slave nodes, this architecture can help your application scale out accommodating your growing users.

Here is the small POC of the concept using the YII framework and MYSQL database.

Although it is extremely robust, the underlying complexity is difficult and the cost of renting and maintaining separate databases and servers may outweigh the benefits offered by this master-slave architecture.

You may need a separate team of experts to pull off this architecture on large-scale application infrastructure and work smoothly.

Hope you find it useful. Thank You!
