A CTO Perspective on Driving a Large-Scale Transformation to the Cloud

Juergen Urbanski

T-Systems International


Global service providers like Deutsche Telekom run some of the largest and most complex IT environments in the world. Traditionally they are not renowned for speed of innovation and operational agility. In fact, most analysts would characterize large incumbent service providers as operating in a “Red Ocean” of margin pressure, cost cutting, organizational complexity, and very long-term investment cycles. Yet Cloud is a “Blue Ocean” growth opportunity. Success in Cloud requires speed, agility, innovation and fast fail-forward organizational learning to succeed.

In this session, participants will learn how Deutsche Telekom is driving a large-scale transformation of IT services production towards cloud-enabled business outcomes such as rapid innovation, fast time to market, high capital efficiency and advanced cloud security. At Deutsche Telekom’s enterprise customer unit T-Systems for instance, Cloud accounts for 5% of its Euro 10 billion revenue today but is an area of rapid growth. Capitalizing on this Cloud opportunity will require massive changes in how ICT services are designed, sold and produced, including changes in the economic model. This is a multi-year journey given the scale of the challenge, spanning more than 90 data centers, 1.2m square feet of data center space, 60,000 servers and 3.3m productive SAP users served from the cloud. This session will outline how T-Systems is leveraging innovation from strategic vendors like VMware to achieve highly modular IT services production platforms which make it possible to bring new services to market quickly, how production capacity is pooled across various countries so that output can be shifted flexibly between sites, and how end-to-end automation ensures high labor productivity and high flexibility.


After 10 years in Silicon Valley serving some of the largest enterprise technology sellers such as NetApp, HP, Oracle, Microsoft, SAP and Symantec on product development issues, Juergen Urbanski has joined one of the top five European buy-side organisations to lead the CTO function for T-Systems, the €10 bn IT services division of Deutsche Telekom. As the Chief Technologist of T-Systems, he is the top executive responsible for the development and application of innovative technologies with the goal of growing revenue and profitability.

As the technical lead on Deutsche Telekom’s four-member Cloud Leadership Team, he is accountable for driving the transformation of ICT services production towards cloud-enabled business outcomes such as rapid innovation, fast time to market, high capital efficiency and advanced cloud security. He also oversees T-Systems' Global Architecture Function, comprising 70 architects and technical professionals in the research, design and development of new ICT services. As a change agent tasked with driving innovation, he works closely with C-level executives and other SVPs to develop the overall business strategy and drive how technology can better serve the goals of the organization.

One example of his successful execution track record is that T-Systems has become the first service provider in continental Europe to join the exclusive VMware vCloud Datacenter Partner Program. The resulting T-Systems vCloud Infrastructure-as-a-Service allows customers to extend their own datacenter capacity into T-Systems datacenters at the touch of a button, with the interoperability, manageability and security that customers are used to from their on-premise VMware virtualized infrastructure.

The Relevance of Standardisation Efforts in Future Clouds


We motivate the need of a portable format for cloud applications. A corresponding standard initiative at OASIS called TOSCA is presented, its underlying concepts and selective details are presented. The architecture of an open source middleware supporting TOSCA is sketched. Finally, the use of portable cloud applications in eScience is envisioned.


Frank Leymann is a full professor of computer science and director of the Institute of Architecture of Application Systems at the University of Stuttgart, Germany. His research interests include service oriented computing and middleware, workflow- and business process management, Cloud Computing, transaction processing, integration technology, and architecture patterns. Before accepting his professor position he worked for two decades for IBM Software Group building database and middleware products. Frank worked continuously since the late eighties on workflow technology and became the father of IBM's workflow product set. As an IBM Distinguished Engineer and elected member of the IBM Academy of Technology he contributed to the architecture and strategy of IBM's entire middleware stack as well as IBM's On Demand Computing strategy. From 2000 on, Frank worked as co-architect of the Web Service stack. He is co-author of many Web Service specifications, including WSFL, WS-Addressing, WS-Metadata Exchange, WS-Business Agreement, the WS-Resource Framework set of specifications, WS-HumanTask and BPEL4People; together with Satish Thatte, he was the driving force behind BPEL4WS. Also, he is co-author of BPMN 2.0 and TOSCA. Frank is engaged in multiple third-party and industrially funded research projects focusing on portability of cloud applications, development of cloud services and much more.
