  3. 3. The current challenge for companies is“change management“ (from culture, tothe organisation, to technology).Organisations face many challenges: competition coming out of nowhere , internationalturmoil, rising costs of raw materials, energy and labour, access to qualified knowledgeworkers and an ever accelerating of technological innovation.In this environment, it is not easy to stay on course, have a coherent strategy and at thesame time maintain costs under control.CEOs, CTOs and CIOs have to provide their companies and organisations with a set ofsolutions where the orchestration of a huge array of resources is the key success factor.In this paper, Value Team states how it can support its clients in attaining this ability toorchestrate and govern their organisations through an adaptive use of disruptivetechnologies such as Cloud Computing.The revenues generated by Cloud Computing services are growing worldwide 148.8 US$billion forecast by Gartner for 2014.What is also thought to increase is the adoption of cloud services by both companies andend-users. Over the next 5 years, they will spend US $ 112 billion on software-as-a-service(SaaS), platform-as-a-service (PaaS) and infrastructure-as-a-service (IaaS).Coping with the world of Cloud Computing implies a mindset shift and requires the know-how and experience from those who have it. It is the combined knowledge of the assetsinvolved, like that of technology, organisation and resources together with that of theenvironments, like the infrastructure, the platforms and the applications.Value Team, with competences, methodologies and experiences, aims today to serve themarket as a Cloud Services Enabler. ICT governance in this relatively new paradigm, is aquestion of balancing the competitive cost of not using the cloud, against the risks of actuallyusing it. There are opportunities and risks to take into account. This requires a fairassessment of the situation, and to face and address themes such as data and infrastructuresecurity as well as quality of service requirements.So how are organisations reacting to the “paradigm shift” which “cloud” stimulates?Telecommunications operators are investing in the development of those advanced serviceswhich Cloud Computing enables to introduce ICT cloud offerings to their markets.Financial Services and Insurance are looking to Cloud Computing not only to optimise costsand deliver efficiency, but also to improve existing channels and exploit new ones.In the Utilities market, remote-reading and remote-management are areas where governedCloud Computing delivers interesting real-time synergies when combined with innovativeCRM platforms and the “internet of things”. 3
  4. 4. For Government (both central and local) the role of Cloud Computing, along with theadoption of “open source” technologies is even more crucial in delivering digital services tothe citizens.We believe that the overall challenge can be paraphrased in “governing the context”.This means to address ever-growing expectations of users towards technology (don’t we allexpect our ICT operations to run as smoothly as the commodities we use every day: easy asthe music on our iPod? safe as our Volvo, and as much fun as drinking our Coke?). It meansto control securely virtual environments, deliver services seamlessly on time, on budget andin an elastic fashion.It means to make more and more services available on a self-provisioning and self-serving basis. It means to run business-oriented“The revenues services in the cloud.generated by cloud The managers of our clients and prospectscomputing services are all facing this “shift” and we are aware of that.

Finally there isthe emergence of strong business models that leverage the “social” side of internetcomputing. Facebook, Twitter, Google mail, Dropbox etc. are now household names.These disruptive tools (and others) have boosted overall productivity and are a strongreinforcing trend in the adoption of Cloud Computing which exalt the horizontal scalability,typical of “social networks”.The provisioning of these services, which when you look at Amazon or Google, seems to beperformed effortlessly, actually requires massive preparation and a general mobilisation of ITresources which is far from easy to execute.In this ever-changing framework, the Value Team value proposition is independent of theCloud Computing services and IT offerings currently on the market. At our core, as a4
  5. 5. strategic consulting company specialised in ICT themes and as a systems integrator, ValueTeam has the capability to design and enable Cloud Computing, and also to engineer anddeliver the instruments necessary to govern the cloud and eliminate the risk. That’s why wedescribe ourselves as a Cloud Services Enabler.In fact, in spite of the great hype which surrounds “cloud”, we are fully aware of the fact thatalthough “cloud” is often referred to as a “game changer”, so have the rules of the gamechanged!. Best practices in the cloud are yet to be established and the integration ofsystems, business rules and legal frameworks is far from simple in terms of analysis,process and execution. It is facing and overcoming these various degrees of complexity thatwe aim to deliver to our clients and prospects.Finally we also offer a selection of Software-as-a-Service turnkey solutions built upon ourdirect experience in the market. This serves also to prove our ability to implement in the firstperson cloud services, and to build our credibility in the eyes of our clients and prospectswhen it come to putting our money where our mouth is.Navigating the cloud is not easy but Value Team is ready to guide you. 5

  25. 25. HOW TO NAVIGATE IN THE CLOUDSTHE APPROACH PROPOSED.To navigate in the vast world of Cloud Computing it is necessary to count on a consolidatedapproach to methodology and use tools and applications suited to governance management of‘services’’.Value Team’s Cloud offering can be summarised as follows: DESIGN GOVERNANCE SaaS SERVICES INSTRUMENTS CONSULTANCY SERVICES & CONSULTANCY & OFF THE SHELF APPROACH & SET UP IMPLEMENTATION SERVICES PROPRIETARY PRODUCTS METHODOLGY LINKED TO THE FOR THE ENTERPRISE INFRASTRUCTURES AND MARKET WITH OUSOURCING SERVICES Key factors Key factors Key factors • Scouting and auditing of • Audit of the governance • Internally developed the services, processes, and “factory” infrastructure products which better meet policies and the • Re-engineering of customer needs supporting KPIS and applications for Cloud • Technological competency SLAs; (physical to virtual) and of and installation at large • Service simulation design, the development, testing clients validation to support the and deployment economic models environments for elastic delivery Activities Activities Activities 1.

  26. 26. The method of approach for Cloud Computing applied by Value Team is advantageous because:• it is action-based: it enables the set up of a series of preventive actions and risk mitigation;• it is distributed and close to the potential points of failure of the systems and processes;• it is independent and high level, integrating with the decision systems available on the market;• it optimises just-in-time resource provisioning to respect the service levels required by business;• it enables a pay-for-use licensing model.The challenge to private or public organisations is that of governing the risks while fully exploitingthe opportunities, which this new model proposes, that is succeeding in managing the Cloud,which delivers business oriented added value services.In this context, the key role is that of defining the operational model of Cloud utilisation within thecompany, enabling services with defined, dynamic Service Levels and aggregating in housefunctionalities and those sourced from other Clouds (private, public and hybrid).With our experience all along the value chain (consultancy, projects and services), Value Team isan international partner for both enterprise and government organisations, as well as forinfrastructure providers, who knows how to navigate You in the Cloud.Value Team is an IT consultancy and services company developing innovative solutions forbusiness, whose offer covers the entire value chain.Counting on more than 3000 professionals world wide, with a significant presence in Italy, Europeand Latin America, Value Team works for major multinationals and leaders in their respectivesectors and geographic areas, and has always collaborated with the principal universities andcentres of research and innovation.. “Value Team is an international partner for both enterprise, government organisations and for infrastructure providers, who knows how to navigarte You to the Cloud” 26
