Microsoft and T-Systems have signed a five-year agreement with Shell that will allow Shell employees to work together online globally.

Under the agreement, Shell will buy SharePoint services via the Internet to increase flexibility at work and to reduce costs.

T-Systems will provide Shell employees a customised version of the Microsoft SharePoint offering virtually, from its own data centre by April, 2011.

The new offering will allow Shell employees to collaborate on an enterprise-wide capability to work virtually in the cloud from anywhere at any time.

Further, Microsoft and T-Systems will also provide a central platform for various applications including: document and content management, organisation and collaboration in project work.

T-Systems Deutsche telekom board of management member and CEO Reinhard Clemens said this is a significant addition to their current contract and puts Shell at the forefront of innovation by combining the data security features of private clouds with the benefits of fully scalable public clouds.
