Microsoft Brings Its Cloud To New Territory by Barb Darrow @FortuneMagazine May 10, 2016, 1:08 PM EDT E-mail Tweet Facebook Linkedin Share icons The multi-billion-dollar cloud expansion by major tech players continued Tuesday with Microsoft saying that it has opened two previously announced data center “regions” in Toronto and Quebec City, Canada and that it will open two more in South Korea, one in Seoul and another near Busan. Both are slated to come online early next year. Microsoft msft now claims Azure operates out of 24 regions, with another eight slated to come online at some undisclosed point in the future. Microsoft Azure, which runs in these data centers, competes with market leader Amazon amzn Web Services in a global market for public cloud services.

AWS says it serves 12 regions worldwide. Most of those AWS regions comprise more than one “availability zone,” basically a separate data center facility with its own power source and other infrastructure so that it can operate independently of the others. Note: this story was updated at 3:58 p.m. EDT on May 11 to reflect that Microsoft plans to open two data center regions in Korea and with their intended launch dates.
