HP Enterprise Services and Microsoft have partnered for a global, four-year initiative to deliver Microsoft’s communications and collaboration applications via global private and public cloud services.

Under the agreement, HP and Microsoft will offer private and public cloud solutions. HP and Microsoft engineering resources will collaborate to deploy, support and enhance the new solutions. The solutions will launch globally, with initial availability this month in Australia, Canada, the United Kingdom and the United States.

HP and Microsoft have a long history of working together, going back some 25 years or so.
