Telefónica is a global telecommunications company based in Spain. Tim Cheung is part of the U.K. division O2, which is the primary sponsor of the widely recognized O2 Arena in Greenwich Peninsula, London, host to the 2012 Summer Olympics.

Within O2, Tim works on the Wi-Fi team providing free Wi-Fi service to end users across the U.K. O2 has approximately 14,000 hotspots and 23 million registered users to date. Of those registered users, 2.5 million use the service daily. In this day and age these numbers aren’t astronomical, but they do present challenges in the way O2 operates. This talk will present some first-hand insight into the following:

  • How many times a day/week/month should you deploy to your production environment?
  • How to manage customer demand for delivery of products and services in increasingly shorter timeframes.
  • Is the production environment governed by a strict change management process?
  • How can you safely and reliably push implemented changes without service disruption?
