Abstract
Over the last few years we have seen a rapid growth in the Web of Data - machine readable data available on the Web using Web standards such as RDF(S) and SPARQL. When last mapped in 2011 tens of billions of Linked Open Data statements were available connected by nearly 500M links. Technologies associated with the Web of Data have now been take up by governments (especially the US and UK Governments) and major Web and Media players such as Google, Facebook, Yahoo!, Microsoft and the BBC. In this talk I will describe work that we have been carrying out in the area which we term "Linked Services" which seeks to connect the spheres of Linked Data and Web services to form a new global computing platform. I will also cover ongoing work where we are transforming SAP's Unified Service Description Language to a Linked Data format.

Abstract
The concept of CLOUD Computing has been a hot talking point for some years. However, there are as yet relatively few business applications running using CLOUDs although the use of CLOUDs for emailing, sharing office documents and social media is well-established. Cutting through the hype it is possible to classify kinds of CLOUD offerings and examine their advantages and disadvantages with respect to business requirements. These challenges and opportunities are technical, economic, legal and environmental. Two reports from expert groups convened by the European Commission under the chairmanship of the author document the state of the art, the opportunities and challenges. This leads to a roadmap for the widespread take-up and adoption of CLOUD computing. A key point of the roadmap is the provision of a systems development environment to allow flexible redeployment of applications across one or more CLOUD offerings. The PaaSage project ¡V part-funded by the European Commission ¡V addresses this opportunity.
