At World Hosting Days 2014 Anthony G. Nichols, VP IT at Opera Software, ASA, gave a definitive answer to the question; “You put your servers where?”. Opera Software provides server-assisted mobile browsing to over 250 million users around the world and continues to grow. In this Nichols explains Opera?s site selection process for colocation, how this has changed over time, and uses the specific case for Iceland as an illustrative case. In this talk he describes some of the particular challenges of this service, how Opera achieves reliability across multiple sites and the factors considered during the RFP which range from PUE to power cost, from latency to density.
