How we transfer millions of Badoo users between data centers

Alexander Krasheninnikov - PHP developer Badoo

I work in the Badoo platform development department. I am engaged in photo infrastructure, user data migration, deployment tools. The main language of development is PHP, but I also gladly use Java and Python.

The report will tell about the transfer of user data within the data center, as well as between data centers.
Most large projects live in more than one data center. Obviously, this is due to the resiliency of the infrastructure and to ensure minimum access time for the user. If the user moves to a country for which another data center is beneficial, it is necessary to transfer data.
In the report I will tell about:

• features of database transfer with user information, photos and service updates;
• ensuring the integrity of the transferred data;
• software implementation of the transfer process;
• hardware infrastructure supporting this process.

See you at DevConf 2015!
