Why MySQL Enterprise Edition
Before launching commercial services, Mobitel used the MySQL Community version for development and testing. When choosing the right database for its tier-2 applications, Mobitel considered EnterpriseDB and Oracle Database but decided on MySQL Enterprise Edition for its superior price-performance ratio and ease of administration.
"MySQL has a very low level of complexity, yet still offers a wide range of database features and options. We can provision a database for developers in no time compared to other databases. Routine admin tasks are straightforward and any member in our DBA team can pitch in quickly to administrate MySQL databases. It is so flexible and also delivers a reduced total cost of ownership," said Indika Alahapperuma, IT Administration, Mobitel (Private) Limited.
Mobitel worked with Millennium, an Oracle Platinum Partner, to deploy the solution in 2016. Running its own datacenters in Colombo, Mobitel opted for a source-replica configuration with one node in the primary site and the second node in a disaster recovery site. The disaster recovery site will be completed during the course of this year.
Mobitel is currently preparing to upgrade to MySQL Enterprise Edition 8.0 and MySQL Cluster Carrier Grade Edition 8.0 to use advanced features such as MySQL InnoDB Cluster, MySQL Enterprise Monitor, and MySQL Enterprise Backup.
Mobitel bridges the digital divide in Sri Lanka by delivering the latest mobile communications technologies to both residential and business customers. The company operates 3,500 base stations across the island and is currently adding another 1,800 stations to achieve 100% population coverage, currently serving 5 million subscribers. With an overall investment of more than US$ 500 million to date, Mobitel is contributing to Sri Lanka's transformation into the 'Wonder of Asia'.
