Submarine cable operator surfaces as cloud computing host

Global Cloud Xchange, a provider of business communications services, plans to sharpen its focus on China and other emerging markets as it builds an extensive “cloud computing” infrastructure.  The company, formerly known as Reliance Globalcom, owns and operates the world’s largest private undersea cable system. It announced its new corporate identity and strategy in New York on Tuesday.  “We aim to deliver the world’s true cloud ecosystem globally,” chief executive Bill Barney said in an interview before the firm’s rebranding launch.
