Amazon-Accenture Tieup Threatens IBM, HP in Tech Services - Bloomberg Business

Accenture also recently acquired Cloud Sherpas, "a leader in cloud advisory and technology services specializing in Google, Salesforce and ServiceNow" (quoting from an Accenture press release)

"As Amazon brings Big Five consulting firms such as Accenture on board, more and more companies could be tempted to ditch traditional IT services companies for AWS, which offers more flexible contract terms.
To compete, the likes of HP and IBM have had to build up their own cloud services offerings and stop infighting between their sales organizations, which tend to squabble over cloud versus traditional contracts, said Brian Gracely, an analyst at Wikibon.
“Most of the traditional vendors haven’t figured a way to change their compensation model,” he said."
