Professional Experience
Booking.com, Amsterdam/Madrid
Sep 2007 – Present
MySQL DBA. The environment initially comprised of about 40 servers, but has grown with the company
to close to 2000 database servers split over 3 datacentres.
My job, starting as the first DBA at booking.com, has involved:
 the automation of the installation of these servers using pxeboot and kickstart (CentOS servers)
 the appropriate configuration using puppet, so that all needed software is fully installed and the
databases are automatically built, being cloned from other running servers when that has been
possible.
 Configuration of the MySQL servers according to the instances' specific usage, needs and
environment, including dynamic configuration changes of the running MySQL servers (with
puppet).
 Responsibilities also include monitoring the servers using nagios, MySQL Enterprise Manager
and more recently graphite to give us longer term trend information
 Troubleshooting problems (hardware, software, performance), including escalating problems and
discussing with the Oracle support and developers, often with personal 1-to-1 contacts.
 Discussing with developers changes they intended to make, helping them diagnose and remove
bottlenecks.
 Collection of configuration information is also fully automated allowing us to be able to detect
changes and when they occurred and if necessary restore configurations to previous settings.
 Normal maintenance tasks like upgrading MySQL versions, including major version upgrades
(from MySQL 5.0 and we are now using MySQL 5.6 and testing MySQL 5.7 on several
systems) has also been an important task
 Management of the master servers' filer storage, these servers using NetAPP filers with fibre
channel for extra resilience.
 Setting up the development environment so we could rebuild all the database systems with fresh
data, taken from the production environment, on a daily basis.
 Ensuring systems are built so that downtime is minimised and avoided as much as possible: that
is users should not experience downtime even when necessary maintenance needs to take place.
 Frequent travel to the head office in Amsterdam as I work remotely in Booking's Madrid office,
as most IT personnel are now based there.
We have database servers configured a variety of ways, several replication chains (one containing over
300 servers in one chain) but also other systems setup in a master-master, or sharded arrangement
depending on specific application needs.
