8. Research Questions Slide Research Description Research Questions Group 1: Definition of Cloud Computing What is Cloud Computing? How is it defined by scientists, ICT vendors, consultants, analysts and commercial publications? What types of solutions are available? What are its main benefits and risks? What type of cloud solutions are being currently offered in the market? Research Questions Group 2: The Dutch Healthcare Sector What are the current trends, challenges and opportunities in the Dutch Healthcare sector? What is the current role of ICT in the Dutch Healthcare sector? What are the main policies and legislations affecting the use of ICT in Dutch Healthcare organizations? Research Questions Group 3: Cloud Computing in NL Healthcare What are the most relevant opportunities and challenges for adopting Cloud Computing in the Dutch Healthcare sector? Which type of Cloud Computing solutions fit within the current legislative context and political agenda? How do current regulations facilitate or difficult the adoption of Cloud Computing?

12. Phase 1 Results Slide Research Findings Cloud Computing Definition Cloud Computing is the delivery model where on-demand elastic IT capabilities are offered as-a-service through the Internet following a usage based pricing model . SaaS Service Model Other models: - Deployment Model: External vs Internal - Access Model: Private vs Public - Hybrids, Inclusions, Aggregations, etc PaaS IaaS Flexibility Abstraction Use Patterns Use Pattern Examples Resource Optimization PresidioHealth (GoGrid), Rentokil (Google Apps), LA County (Google Apps) Scalability & Elasticity PresidioHealth (Appistry IQ Cloud), Wordpress (MS Azure), Twitter (Amazon S3) HPC NYT (Amazon EC2), Harvard Medical School (Amazon EC2 & Oracle), BT (Amazon EC2) Fail-over / Backup 37signals (Amazon S3), Zmanda (Amazon S3), Jungle Disk (Amazon S3) Faster time-to-market PresidioHealth (Appistry), Siemens (Windows Azure), SugarCRM (Windows Azure) External Knowledge GoGrid (Windows Azure), Associated Press (Windows Azure), Rover (Rackspace Cloud)
Wellcome everyone Introduce me Mention Enovation / Utrecht advisors
This is the structure of my presentation
Scope (Why), Questions (What), Approach & Methods (How)
IT TRENDS Service orientation of consumers and enterprise IT solutions Capable of even more and more with high demands on performance and availability
Ecosystems instead of silos A lot of waste in energy and resources by having to have your own infra Is like trying to create your own energy yourself => highly unproductive and inefficient
These trends are also acknowledge by Gartner placing Cloud Computing as the number 1 strategic priority area for 2010
However the hypy is obvious. Gartner Hype Cycle, 2009: Still at the peak of inflated expectations with 2 to 5 years to mainstream adoption
Our main research question is if it is possible to use cloud computing in the Dutch healthcare sector. For this reason I divided the research in three main areas: cloud, healthcare NL, and a third one linking the findings from these two phases in an meta-artifact
I applied Jarvinen framework to determine the most appropriate research approach and methods according to the research question that we aim to answer
From an interpretative perspective we have considered how all relevant stakeholder define the concept of cloud computing There are 100s of definitions with sometimes contradictory concepts. Berkeley: Does not emphasize abstraction of infrastructure explicitly & excludes private clouds from the definition. Telefonica: Does not distinguish cloud services from clouds and does not provide definitive economic implications
Based on existing definitions from scientific papers, NIST, IT analysts and consultants, and media. On-demand: accessible and ready when needed, low deployment times Computing Capabilities: software, hardware, platforms, etc as-a-service: regulated by SLA, payment for delivered services Internet: delivered electronically Usage based pricing: pay only for what you use. Excluded from definition: hardware virtualization, self-service interface, optimum resource utilization Combinations are feasible for each specific situation

(1) 9% of all jobs in the EU, More than 6% of EU GDP, Citizens are both consuming and funding services (2) NL: 40% public and 60% private financed (one of top 3 most private systems in the EU) Private Funding: (+) market forces act (e.g. price competition, etc) but (-) low profitable services are excluded (e.g. research for rare diseases) (3) To protect citizen’s (e.g. H1N1 virus spread). Errors make it quick to the media (4) Thus also increasing costs => cost grow faster than GDP growth rate.
It is certainly possible to deploy compliant cloud solutions See HIPAA / PCI case studies like Presidio Health Smart constructions can leverage cloud solutions while maintaining compliance with laws and regulations Hybrid models for non-mission critical data or when persistent data is maintained on-premises
SaaS for Healthcare in the US (HIPAA & PCI)Focus on agility to improve time-to-market (development of web-based apps)Scaling to meet peaks in demand 24/7Approach: Open source software (Spring Framework, Tomcat, Java) & Oracle database on an hybrid infrastructure IaaS + PaaS + on-premises Compliance HIPAA & PCI => data in own infrastructure (DB server) The other servers do NOT store any data Internet Application server have each its own firewall Appistry Application Servers: no internet access, distributed on 3 boxes, managed by Appistry platform. Comodo firewall scanning Presidio Benefits from using the cloud Increased computing power by 70% Lowered total IT costs: reduced physical space (lower cost & complexity) at collocation, usage based model (resource optimization) Increased scalability and reliability: on-demand Maintained security: persistent data in collocated server, limited internet access to web servers. Passing some of the savings to customers: lower selling costs for apps.
Analysis theory = phase 1 and 2 Design theory = phase 3
Thank you for your attention. Now we have some time to answer your questions.
