Gaithersburg, Md.--GE Global eXchange Services and Paris-based Cap Gemini Ernst & Young have entered into an alliance to jointly provide Internet technologies and consulting services to b-to-b marketplaces. GXS will provide software and advisory services on bringing legacy systems into e-based environments. Cap Gemini Ernst & Young will offer related methodologies and integration services. The deal underscores GXS' rapid morphing from yet another b-to-b technology provider into a serious competitor to kingpin IBM Global Services. Cap Gemini Ernst & Young, meanwhile, is intent on making b-to-b inroads now that its acquisition of New York-based Ernst & Young L.L.P.'s consulting practice is complete.
