1 The Cloud Changing the Business Ecosystem kpmg.com/in
3 Foreword Technology has always played the role of a disruptive force that somehow connects discontinuities and changes business models, ecosystems, or even the world order. Paradoxically, it has sometimes created a level playing field, and at times 'unfair' advantages for some countries or enterprises. This is evident all through out history right from the stone-age, to the industrial revolution, to the silicon era, to the internet/dot com age and to the current age of convergence/mobility. Technology could transform the world into the virtual space, enabling endless cycle of innovation. Advanced economies like US, UK, Germany, and Japan have been at the forefront of combining innovation and technology. This has enabled them to become superpowers that have the economical, defensive and financial muscle. Same has been the case with enterprises like IBM, Microsoft, Google, Apple, Siemens, Sony, CISCO, Nokia, etc. At the same time, it has created a level playing field with the rise of telecommunications and the internet. This leveling has helped in creating emerging leaders like India and China who are leveraging favorable demographics with technology. Technology is often a savior during the downward economic cycles as it enables the creation of more efficient business models and ecosystems. Ironically, sometimes it also leads to economic downturns as the euphoria over technology powered business models cause unrealistic expectations in the capital markets, creating bubbles which inevitably burst for e.g. the dot com burst. The Cloud is another such phenomenon that has stirred up interests and investments in many parts of the world. Research has indicated that the worldwide Cloud services revenue is forecast to reach USD 68.3 billion in 2010, a percent increase over the previous year. There are many challenges and questions ranging from data privacy and security to whether the time has come for the Cloud. The future belongs to those who will truly understand the present scenario, manage risks, and innovate with a vision to create a new order.

5 Each decade, since the 1970s, has seen the evolution of IT into a whole new avatar. Mainframes (1970s), Rise of the Personal Computer (1980s), Client Server Architecture (1990s), are a few well known avatars. Meanwhile, what helped the adoption of these advances in IT was that each new avatar was preceded by a recessionary phase. Recessions brought about a greater need for businesses to improve efficiency levels and increase profitability. As a result, businesses and individual users rapidly adopted the modern avatars of IT with the objective of realizing their benefits. The double dip recession, in the early part of the 1980s, was almost immediately followed by the Rise of the Personal Computer (PC). The number of PCs installed grew from less than 1 million in 1980 to 1 over 100 million by the end of the decade. Similarly, the recession due to debt, rising inflation, etc. in the first half of the 1990s was followed by the growth of the Client Server Architecture and the internet. There were only a few thousand users of 1 the internet at the start of the decade which ended with over 300 million users. Recently the world has gone through an economic downturn and there is an even stronger need for organizations to improve efficiencies by using collaborative solutions and real time information exchange. The Cloud could therefore be the next big thing with it gaining prominence during the recent credit crisis. The promise of the Cloud possibly lies in the flexibility, scalability and cost benefits made available through the as-a-service paradigm. Impact of IT evolution The increasing use of IT brought with it overheads in the implementation and maintenance of computing systems. The amount of time and finances invested in managing IT, which has become complex over a period, has increased exponentially. This also resulted in the growth of IT companies and the outsourcing of IT management. The last century saw IT becoming a key business enabler. The dot com bust followed by the recession and financial crisis, saw an increasing demand from IT to do more with less. Technology and connectivity meanwhile evolved quickly with the introduction and adoption of technologies like XML, SOA, Web 2.0 and high speed internet connectivity. However, the impact of the computing evolution cannot be seen from the narrow lens of IT impacts only. IT has been one of the key disruptive technologies for the last many decades. It has changed how individuals and businesses function. The constant evolution of computing has helped businesses to automate and innovate providing them a competitive advantage in the global marketplace. A study of business history would reveal that the rapid rise of US-based organizations was due to their ability to quickly leverage IT for their business needs. On the other hand, organizations from other parts of the world were relatively slow in leveraging IT. However, over time IT has become a hygiene factor and large scale adoption has led to leveling of the playing field. Nevertheless, with the coming of the Cloud, organizations are once again at the crossroad of technology. Early adoption of the Cloud can provide organizations with an opportunity to transform their business models and gain a competitive edge. While cost reduction is one of the benefits, several other benefits accrue to organizations. Organizations would be able to concentrate on their core competencies while leaving the task of running IT infrastructure to the Cloud service providers. Further, through the adoption of the Cloud, organizations are expected to become more nimble. The Cloud would help them quickly provision resources for business opportunities, which could otherwise be lost. The Cloud also enables organizations to build virtual and "open" business processes, enabling its various stakeholders including customers, business partners, suppliers, etc. to connect and do business more seamlessly. 1.

In the early stages of the computing evolution, IT was mainly restricted to business use. However, the coming of PCs helped individuals automate and enhance their own lifestyle. From being able to store personal information, to automating their finances, IT has emerged as a personal priority for individuals. The convergence of business and Internet, IT has, in fact, changed the lifestyle of people. Today it is impossible to imagine a life without a search engine, which delivers information at a click of a button! Moreover, through social networking, virtual communities have become an indispensible part of our lives. Facebook, Twitter, LinkedIn and other virtual platforms have enabled millions to connect, share and leverage technology to enhance their life experiences. These platforms are different shapes of the Cloud which enables rapid development and scalability. The coming together of technology, business needs and economic factors was the perfect storm which led to the birth of the Cloud. Anatomy of the Cloud In order to understand the Cloud, it is important to understand what can exactly be called a Cloud. While there are numerous definitions of the Cloud, it can be explained very simply as follows: The Cloud = Internet-based data access & exchange + Internet-based access to low cost computing and applications In order for any offering to be termed as a Cloud it should have the following characteristics: Characteristics = On-Demand Self-Service Internet Accessibility Pooled Resources Elastic Capacity Usage-Based Billing
7 Further, the Cloud is defined in terms of three Service models and four deployment models as depicted below: Cloud Service Models Cloud Deployment Models Software as a Service Business operations over a network SaaS Platform as a Service Deploy customer-created applications to a Cloud PaaS Infrastructure as a Service Rent processing, storage, network, other computing resources IaaS Private Operated for a single organizations Public Available to the general public or large industry group, owned by an organization selling Cloud services Community Shared by several organizations, supporting a specific community Hybrid Two or more Clouds that remain unique but are bound by technology that enables data and application portability Drivers and challenges of the Cloud There are several drivers and challenges of Cloud adoption today. The Cloud makes a compelling business case on both technical and commercial aspects. It seeks to 2 3 replace the CAPEX component of the current IT infrastructure with a 'Pay-as-you-go' or OPEX model. This model needs to be carefully studied by organizations to ascertain its impact on the cash flow and profitability. Further, tax-related issues also need to be taken into account in order to arrive at the real implications of the adoption of the Cloud from a bottom line perspective. At the same time, organizations must take into account non-commercial benefits such as scalability and ease of implementation. These benefits of the Cloud help organizations quickly source computing resources On-Demand. While there is a strong case for the adoption of the Cloud, there are several challenges that need to be overcome. Security continues to be the key challenge for Cloud adoption. Organizations are yet to get comfortable with the idea that their data would be secure and would not be misused once ported onto the Cloud. Other major challenges are availability, regulatory and tax-related issues. Drivers and challenges of the Cloud Figure 02 Macro Forces Macro Forces Improvements in bandwidth, commodity server market, grid computing & database, and network storage systems Pay-as-you-go Virtual and On-demand Agility, Flexibility and Elasticity Multi - Tenancy Ease of Implementation Pooled Resources Privacy and security Reliability and availability Transition and execution risks Limited scope for customization Cultural resistance Regulatory ambiguity Issues of taxation Different data privacy standards in different regions, no standard code for cloud, taxation issues and lack of technical personnel DRIVERS CHALLENGES Source: KPMG s The Cloud: Changing the Business Ecosystem, Refer to glossary 3. Refer to glossary
8 Changing IT ecosystem The Cloud is the emergence of a new way of delivering computing services and as such it will impact nearly all facets of the IT ecosystem. Most importantly, IT solutions and services vendors will now need to adapt their infrastructure, people and processes. People The Chief Information Officers (CIOs) role has undergone a few changes since the beginning of the 21st century. With the advent of the Cloud, CIOs would now be expected to play the part of a Strategic Executive who would work towards bringing about business transformation through innovation in the way modern technology is adopted by the organization. The CIO would also be expected to aptly guide the leadership on the development and the execution of a Cloud strategy. The in-house IT team would need to focus more on using the Cloud to quickly meet the business needs rather than configuration and implementation of application on in-house hardware. A deeper understanding of the Cloud paradigm would indicate that business leaders have a major role in the adoption of the Cloud. Roles and responsibilities of the leadership Figure 03 Cloud Advisors Business Benefits STRATEGIC Vision Strategic Direction Cloud Business Model CEO Business Transformation TACTICAL Financial Evaluation Technical Evaluation Adoption Roadmap CFO, CIO, CTO Cost Optimization/ Process Efficiency Innovation OPERATIONAL Implementation Plans Migration Deployment & Maintenance IT Team, Vendors Operational Efficiency Source: KPMG's The Cloud: Changing the Business Ecosystem, 2011 This is primarily because implementing the Cloud is largely a strategic business decision rather than a purely technology decision. Business leaders have a much larger role to play in the adoption of Cloud services as it is a decision that would be driven by business needs and financial considerations. Processes The ability to quickly provision computing resources would enable organizations to leverage the Cloud to quickly meet business needs. Businesses could easily scale up and down, responding to market needs in a nimble manner. This could lead to the development of new business models and enable organizations to serve their clients more effectively. SaaS offerings would also have significant impact on business processes and would lead to large scale standardization. Infrastructure On-Premise / Co-located data centers could be substituted through the use of IaaS service model of the Cloud. Similarly, developing and hosting applications through the PaaS service model would be a
9 cost-effective and time saving approach to application development. Delivery and the use of software over the internet based on the Cloud service model of SaaS makes it easier for users to source and manage software in a dynamic environment. This would necessitate use of a high capacity and reliable network connectivity to access the Cloud. Impact of the Cloud on the Industry While the Cloud could benefit all sectors in one way or the other, the impact will be fairly emphatic in certain sectors. We believe that the Cloud would be most advantageous to the Government, Healthcare, and Education sectors, as the stakeholders include large sections of society. Government Governments can leverage the Cloud to bridge the communication divide, especially with those citizens that reside in remote parts of the country. The Cloud could also be used to increase interoperability between various government agencies, reduce redundancy, track / monitor the effectiveness of government schemes. Computing resources shared between Central and State governments would result in reducing costs by leveraging existing infrastructure. Transparency in Government can be achieved at a faster pace through the adoption of Cloud. The Cloud has the potential of transforming this sector, to benefit not only the Government itself, but also millions of people. Healthcare The Cloud is a paradigm shift in the use of Healthcare Information Technology (HIT), which enables stakeholders to focus more on their core competencies. In the case of the Healthcare industry it would provide for the seamless management and access to Electronic Health Records (EHRs) of patients. This would facilitate the provisioning of healthcare products and services to patients located in remote areas and those that have limited access to quality medical services. The use of the Cloud could possibly result in a change in business models, automation of processes, streamlining of workflows, and a consolidation of IT assets for Healthcare service providers. The creation of an integrated Healthcare ecosystem would help the providers of healthcare services make available the best of services to patients. Education Though the Education sector has seen significant transformation in the last decade, the challenges of high cost, limited reach and quality are still matters of grave concern. The Cloud might just prove to be the catalyst that will enable the sector overcome these barriers. The Education sector which has already embraced the use of the Cloud for services could now consider moving critical applications such as Virtual Learning Environment (VLE), Learning Management Systems (LMS) and Student Information System (SIS) into the Cloud. The Cloud promises to make the Education system more collaborative and innovative with unique resources readily available to all students. This could change the way in which education is delivered and financed. Small and Medium Enterprises (SMEs) SMEs have been largely unable to take advantage of IT systems and solutions due to the high up front costs of sourcing and deploying the same. Consequently, they are known to face issues in the management of their supply chains, financials, inventories, customer relationships, and human resources. The Cloud reduces the cost burden of using IT for SMEs, especially because Cloud services provided access to on a usage based pricing model. Other benefits like scalability, flexibility, and On-Demand service are highly attractive proposition to this user group. Thus the adoption of the Cloud, amongst the SMEs could be the highest in comparison to the rest of the business community.
10 Embracing the Cloud Before venturing to embrace the Cloud, organizations would need to evaluate a number of concerns. These concerns can be grouped into two parts namely Business Factors and Technical Factors. Migration concerns of the Cloud Figure 04 BUSINESS FACTORS TECHNICAL FACTORS Existing Investments Costs Tax considerations Cash flow / Profitability Data Security Regulations Provisioning Cloud Adoption Existing infrastructure Security Complexity Availability Network & Support Local access and storage IT skills SLAs Source: KPMG's The Cloud: Changing the Business Ecosystem, 2011 To attain the maximum benefit from migration to the Cloud it is essential that organizations develop a Cloud Strategy, which takes into consideration commercial and technical concerns. This strategy should not only define how a move to the Cloud would be made but also identify various factors, which include the type / combination of Cloud service and deployment models to be used, how services of the Cloud would be governed, the process of identifying the requirement for, and deployment of new Cloud services, the level of interoperability between Cloud services, etc. In a gist, to get the maximum out of the Cloud, it is important that organizations should carefully plan their move taking into consideration commercial and technical concerns. Conclusion The Cloud is a game changing phase of IT that is not only impacting the way computing services are and will be delivered but also the way in which users will use IT. The Cloud promises several benefits in commercial and technical terms but the challenges too need to be considered when planning for Cloud adoption. Businesses will also need to redefine their business models to better reflect changing trends in the use of IT i.e. Cloud services. As such, the roles of the leadership will also change to better reflect the realities of the Cloud. Amongst industry sectors, the Government, Healthcare, and Education sectors would benefit the most as the Cloud provides them with the socio-economic reach that they lacked for decades. Similarly, the Cloud promises to deliver affordable, reliable, and flexible computing solutions to SMEs, enabling them to compete more effectively with larger organizations. A move to the Cloud, however, requires a well planned strategy as there are many business and technical constraints that need to be mitigated. Regulations are needed to clear doubts with regards to transfer of data across borders and the ownership / security of data stored on the Cloud. On the whole, the IT solutions and services industry may significantly change in order to accommodate this new service offering. Businesses have and would continue to adopt the Cloud in order to stay ahead of the curve. The Cloud is not just a passing phenomenon but a reality that has just begun to realize its potential.

14 01 Relevance of the Cloud
15 02 Changing role of IT Cloud Computing, popularly known as the Cloud, promises to change the face of Information Technology (IT) as we know it today. IT is recognized not only as a business enabler, but also as a strategic tool that will redefine business objectives. However, of late the proliferation of IT in most large organizations has leveled the playing field. The emergence of the Cloud could lead to a new round of innovation in business processes. Existing business models may need to change to be able to leverage on the strengths of the Cloud. Further, totally new disruptive business models will emerge based on the Cloud. 1 2 Technological advancements such as the introduction of high-speed broadband, 3G and 4G 3 technology (long term evolution), high-efficiency blade servers, network optimization solutions, etc. could enable the IT industry to provide dynamic and value-driven services and solutions. Businesses now demand more flexibility, scalability, cost-efficiency and ease of use from the IT solutions and services used by them. A dynamic IT environment, that caters to real time information requirements, could help businesses not only meet their existing business objectives but also set up new ones.

At the same time, the expectations of customers are also increasing. With companies now looking for new ways to enhance the quality of their products and services through IT, the traditional model seems to be inadequate Sourcing and deploying IT systems and solutions, using the traditional model, may not result in the optimal utilization of resources while requiring large investments to continue functioning. Businesses not only have to setup an in-house (On-Premise / Hosted) computing environment but they also have to build / source IT teams to manage the same thus adding on to costs. 1. Refer to glossary 2. Refer to glossary 3. Refer to glossary
16 03 Some of the key challenges that are associated with the traditional model of sourcing and providing IT services are as follows: Limited IT budget: Initially, the IT budgets of organizations were limited as IT was looked upon as a support function. The recent economic downturn has put a strain on the IT budget of most companies. Setting-up an On-Premise computing environment or upgrading existing systems requires substantial investments. Scalability of systems: Current IT frameworks and design principles are not very flexible and could result in a design overhaul of existing solutions, to accommodate drastic changes to user requirements. E.g. system administrators manage peak demand for server access by investing in additional hardware and software resources which are under utilized during non-peak loads. Longer gestation period for setting up the IT infrastructure: The traditional process of designing, developing, and deployment of solutions is time consuming and iterative. Consequently, this could negatively affect the execution of various business processes especially when there is a need for the rapid development and deployment of applications. Infrastructure management: Management of the entire IT function requires investments in the form of time, professional expertise, and financial investments. Moreover, managing IT infrastructure might not be a core competence of a company. This is a constant challenge in most organizations. Need for enterprise mobility: Owing to convergence in global markets and the need to stay connected round the clock, business executives are now demanding a well connected environment that caters to real-time information interchange. The traditional environment needs a significant overhaul to be able to meet the expectations of a virtualized / connected environment. Factors fostering the growth of the Cloud Per capita PC penetration by region Worldwide Middle East and Africa Asia Pacific Eastern Europe Latin America Japan Western Europe North America Source: Deutsche Bank and Gartner, Report: Changing PC sector, market share, emerging markets, forecast considerations, September Figure PCs per 1000 population Some of the key factors that are driving the acceptance of Cloud services are as follows: Rising computer penetration: The past decade has seen the increasing acceptance of the internet as a medium of communication for businesses. Computers and internet connectivity are the prerequisites for the adoption of the Cloud. Growing penetration of computers is resulting in an increase in the demand for affordable computing solutions. Improvement in bandwidth availability: The past decade has seen the rapid rise in the availability of internet bandwidth at increasingly lower costs. Data transfer rate over wireless networks has now reached 300 Megabytes per second (Mbps) while it stands at a speed of 1 Gigabyte per second (Gbps) for data transfer over wired networks. At the same time, there has also been a significant improvement in the reliability of the connection.
17 04 Innovations in commodity server market: There has been a significant improvement in the quality of servers that are now available, with faster and powerful processors in place. These servers have become more efficient and less expensive making them more viable for the Cloud. Moreover, innovations in interconnect technology (such as InfiniBand), have made the use of servers in clustered environments and application execution more feasible and efficient. Improvements in storage technology: The growing need to share data between various applications in units as big as terabytes is increasing the demand for networked storage - a shift away from direct attached storage. Capabilities of servers to run multiple applications and increased relevance of virtualization have further acted as an impetus for the growth of network storage. Emergence of a new era: The Cloud The Cloud is the emergence of a new era that could possibly revolutionize the way IT is used in business.

18 05 The Cloud is used to cohesively identify a series of technological innovations / advancements in the fields of IT and telecommunications. These advancements have together to complement each other thereby leading to the creation of an offering called the Cloud. As this offering is rather new, businesses are trying to keep pace with the Cloud while trying to grasp the pros and cons of the same. In simple words, the Cloud refers to the process of sharing resources (such as hardware, development platforms and/or software) over the internet. It enables On-Demand network access to a shared pool of dynamically configurable computing resources. These resources are accessed mostly on a pay-per-use or subscription basis. Comparing the traditional ecosystem and the Cloud Figure 04 The Traditional IT Ecosystem SINGLE ORGANIZATION The Cloud Ecosystem MULTI - TENANT USER ENVIRONMENT APPLICATION HOSTING & DEVELOPMENT Service Providers ON PREMISE DATA CENTERS NETWORKS HARDWARE SOFTWARE VIRTUALIZATION SaaS + PaaS + IaaS SERVICE PROVIDERS ON DEMAND Single User Huge Capex Customization is expensive High Implementation Time Mobility & Adaptability are issues Multi Tenant Users Shift to Opex Customization is easier Time to Implement is low Maintenance is done by the Service provider Source: KPMG's The Cloud: Changing the Business Ecosystem, Services of the Cloud, are made available through virtualization and provided on a usage-based pricing model. These resources can be quickly provisioned and easily managed, by the user, without any major inputs from service providers of the Cloud. Customers sign customized Service Level Agreements 5 (SLAs) with service providers of the Cloud to ensure availability of services based on certain guiding principles. 6 Service and deployment models for the Cloud The Cloud definition given by the National Institute of Standards and Technology (NIST), US, is the most widely accepted one. It defines the Cloud as having three service and four deployment models which are as given below: Cloud service model Infrastructure as a Service (IaaS): The provisioning of processing time, storage, networks, and other fundamental computing resources, made available by Cloud service providers for use by customers is known as Infrastructure as a Service (IaaS). These resources can be used to deploy and run arbitrary software which can include operating systems and applications. The service provider is responsible for the management of the underlying Cloud infrastructure. Examples include: Amazon EC2, Zenith s Proud, etc. 4. Refer to glossary 5. Refer to glossary 6. Definitions are based on those given by the National Institute of Standards and Technology (NIST)
19 06 Platform as a Service (PaaS): The capability provided by Cloud service providers, for customers to use to develop and host applications is known as Platform as a Service (PaaS). The customer does not manage or control the underlying infrastructure that includes network, servers, operating systems, software for application development, etc which are managed by the service provider. Examples include: SalesForce.com s Force.com, Wolf Framework s Wolf PaaS, Windows Azure, etc. Software as a Service (SaaS): The delivery of software applications over the internet while being managed by the service provider is known as Software as a Service (SaaS). Customers are not concerned with the regular maintenance, up gradation and the management of the underlying computing infrastructure that is used to host the applications. The applications are accessible from various client devices through web browsers. Examples include: Gmail, Facebook, SalesForce.com, Zoho CRM, etc. Planned adoption for IaaS and SaaS service models is the highest Survey Findings 01 Sixty-eight percent of the initial respondents to KPMG in India s Cloud Survey* indicated that they largely plan to adopt either the SaaS or PaaS service models. Significantly more number of SMEs, i.e. nearly 80 percent, planned to adopt SaaS as compared to larger organizations.
