What is MySQL Replication?
« on: September 03, 2013, 03:29:07 PM »

MySQL replication enables valuable data to be copied and stored in different locations ensuring data security and optimal server performance.

With MySQLs prominence on the market as the largest open source database system, it has transformed the way that businesses operate and manage data. Facilitating the creation of databases and website development, MySQL is renowned for its streamlined code, accessibility and inclusion in the LAMP (Linux, Appache, MySQL, PHP/Perl/Python) stack.

As MySQL is often used to store records of information from databases and inventories from online stores, protecting valuable data is vital. With MySQL replication, an exact copy of a database is replicated onto another server, ensuring that any updates to the master database are immediately made to the other server. Replication ensures availability and reduces the possibility of data loss, which is an important backup procedure.

MySQL replication is useful for a variety of reasons, such as the ability to analyse data without using the main database, backing up data and optimising database performance. Replicating data is useful for single servers that are under large loads and need to be scaled out, so that the speed of the master database is not affected.

Multiple users can access MySQL databases, which serves as a useful tool for businesses. In terms of data analysis, reports can be run on slave servers so that the master database wont be slowed down or corrupted. SSH and VPN tunnels are also used to encrypt data, ensuring total security of data during transfer.

A major benefit of MySQL replication is that data can be replicated across different geographic locations. IP routing allows traffic to flow based on the geographical location of the user, with traffic being divided among different regional servers or data centers. This provides an ideal solution for international businesses and increases the overall performance of the master database.
