EXECUTIVE SUMMARY Cloud computing is hot. But severe business risks and challenges are involved to retrieve the promised business advantages of cloud computing. Conclusions:  The main disadvantages are: security, loss of control, unstable cost structure , potentially decreased business flexibility, integration problems.  An adaptive architecture, including a new business model must be developed to retrieve business value  Organizational changes are needed for adapting the technology (procedures, skills, business model)  Formulate and maintain an exit procedure to change from CSP (Cloud Service Provider).  Cloud computing technologies and business models have not yet reached maturity. Standards are being developed.

OUTLINE This presentation is a brief summary of the research on cloud computing performed under supervision of the Business Management Support Foundation. The following questions will be answered:  What is cloud computing  What are the main disadvantages and pitfalls using cloud computing With Google returning more than 12 million search result on the term ‘cloud computing’ the hype can not be ignored.

HYPE, FAD OR INNOVATION? Cloud computing is rapidly gaining the interest of service providers, programmers and the public as no one wants to miss the new hype. So the real questions need to be answered:  What is the real business value?  What’s the innovative part?  What are keen pitfalls using cloud computing?  Is clustering the same as cloud computing?  What happened with virtualization, grid computing, the automatic data center and autonomic computing?  What are the main risk involved?  What is the new vendor lock-in?

AGENDA What is cloud computing  Definition of cloud computing  Is cloud computing new?  Manifestations of cloud computing  Cloud deployment models  What should cloud computing be? The main disadvantages and pitfalls using cloud computing  Security  Dependency (loss of control)  Cost  Decreased flexibility  Knowledge  Integration New business opportunities and conclusions

DEFINITION OF CLOUD COMPUTING The lack of an agreed single definition makes answering ‘what’ question hard. The NIST definition of cloud computing is: Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. In our opinion this definition covers the field of cloud computing.

IS CLOUD COMPUTING NEW? Cloud computing is not a fundamentally new paradigm Cloud computing draws on existing technologies and approaches, such as:  Utility Computing  Software-as-a-Service  Distributed computing  Centralized data centers What is new is that cloud computing combines and integrates these approaches. Cloud computing can be seen as the logical evolution in outsourcing IT services. The promise is that with cloud computing every company (big or small) can get IT services in a very simple way.

MANIFESTATIONS OF CLOUD COMPUTING Multiple Service models:  SaaS: Software as a Service  PaaS: Platform as a Service  IaaS: Infrastructure as a Service • Implementations of specific business functions • E.g. Google Docs, Salesforce CRM, SAP Business SaaS by Design • Provide computational resources through a platform (Operating Systems) PaaS • Dedicated APIs • Resource Clouds (e.g. CPU’s, memory, storage, network) IaaS • Managed and scalable

CLOUD DEPLOYMENT MODELS To make use of Cloud Computing companies can use services of a CSP (Cloud Service Provider). But be aware of the different cloud service models that are offered:  Private Cloud: Internal within a company data center or dedicated leased;  Public Cloud: Cloud services provided to many customers from a single technology stack;  Hybrid cloud: Offers a possibility to mix private and public cloud services; Private Cloud With a public or hybrid cloud the CSP Uses resource pooling to serve multiple customers using physical and virtual Deployment resources that are dynamically Models assigned and reassigned. Hybrid Public cloud Cloud

WHAT SHOULD CLOUD COMPUTING BE? In our opinion cloud computing should:  Give you extra business value over a long period of time  Ensures that the quick changing business needs can be supported better than using traditional IT services  Be a technology that enables business innovation Currently cloud computing involves:  Virtualization  Automatic Scalability (rapid elasticity)  On-demand deployment  Internet delivery services  Open source software  Open standards  Business innovation and requires business adaptability

DISADVANTAGES USING CLOUD COMPUTING Disclaimer: Cloud computing technologies and business models have not yet reached maturity. So:  All major CSP’s are still working on research and development to give customers the level of services and quality required for crucial business processes. And:  The processes needed within CSP’s and the IT technology used by CSP is growing towards a landscape of extreme complexity. So what are the main disadvantages using cloud computing?

DISADVANTAGES: SECURITY Security:  No control over the business assets (data!). The main assets in every company are its data files with valuable customer information.  A proper security model for cloud computing is not yet developed. Security, privacy and compliancy is still difficult for cloud solutions. Especially for public cloud services.  Physical location of hardware and software is unknown. Site inspections and audits are hard.  Availability. Constant connectivity is required.  Failure to compliance. E.g. HIPAA, SOX, PCI, SAS 70 and audits.  Risk of data loss due to improper backups or system failures in the virtualized environment.

DISADVANTAGES: DEPENDENCY Dependency (loss of control):  Quality problems with CSP  No influence on maintenance levels and fix frequency when using cloud services from a CSP.  No or little insight in CSP contingency procedures. Especially backup, restore and disaster recovery.  No easy migration to an other CSP.  Measurement of resource usage and end user activities lies in the hands of the CSP  Tied to the financial health of another Company.

DISADVANTAGES: COST AND FLEXIBILITY Flexibility:  Special customization not possible.  Possible lower rate of business IT innovation. The technological innovation pace is dictated by CSP. Cost:  Hidden cost (e.g. compliancy regulations, backup, restore, disaster recovery and problem solving.)  Opaque cost structure due to highly flexible usage of cloud services;  Cost advantages is as hard to get when using outsourcing for IT services in a traditional way.  Risk of higher future is charges is real.

DISADVANTAGES: KNOWLEDGE AND INTEGRATION Knowledge:  More and deeper knowledge is required for implementing and managing SLA contracts with CSP’s  Since all knowledge about the working of the cloud (e.g. hardware, software, virtualization, deployment) is concentrated at the CSP, it is hard to get grip on the CSP. Integration:  Integration with equipment hosted in other data centres is difficult to achieve.  Peripherals integration. (Bulk)Printers and local security IT equipment (e.g. access systems) is difficult to integrate. But also (personal) USB devices or smart phones or groupware and email systems are difficult to integrate.

NEEDED ORGANIZATIONAL CHANGES When using cloud computing the following changes are needed:  Adjustment on the main business model  Adjustment on architecture and design for new and current systems  Adjustment on architecture method used to maximize the advantages of the new technology  New approach to implement new solutions using CSP services  Adjustment on maintenance model  Adjustment on cost model  Paradigm shift at current business and IT departments.

NEW BUSINESS OPPORTUNITIES? Cloud computing can enable new business opportunities. New business models possible are e.g.:  On demand IT  Self service IT  Pay-by-use These models are possible from a infrastructure perspective , but also out of a business application perspective.

DON’T GO?! Cloud computing is about an automatic data center from a IT perspective. But business and IT are allied. One of the major changes that comes with cloud computing is that there is a need to:  Automate the processes around the various tools and techniques used So if you did not succeed the last 4 years with e.g.:  SOA  Building an automatic CMDB  Automatic SCM (Software Configuration Management)  Quality improvement for business and IT processes  Governance  Security baselines Think again on how using cloud computing will impact your current problem fields.

CONCLUSIONS Cloud computing can give a significant business advantage! To make Cloud Computing successful :  Understand the risks involved  An adaptive architecture, including a new business model must be developed to retrieve new business value  Organizational changes are needed for adapting the technology (procedures, skills, business model)  Understand the technology used by your CSP (Cloud Service Provider)  Formulate and maintain an exit procedure to change from CSP.

ADVISE To make Cloud Computing successful :  Stay compliance : SOX, HIPAA, ISO , NIST e.g.  Be robust for network failures and network performance issues.  Stay close to open source and open standard solutions when choosing a CSP (Cloud Service Provider)  Work from within a defined architecture to retrieve the wanted results using cloud computing  Be aware of the current lack of standards when using or implementing cloud computing.  Since long-term experience is lacking with the use of cloud computing real business advantages in relation to competitors is possible. But be aware of the many pitfalls that makes you inflexible in the future.

FUTURE OR PRESENT? The cloud computing paradigm is not the future. The technology is already available for a number of years. The future is about developing innovative business models that use the technological advantages that cloud computing enables.
