Outline What is cloud computing? Cloud computing plain and simple, and more.. Cloud computing plain and simple.. Cloud computing in Healthcare Conclusions and thoughts 3

Slide 4

Cloud Computing: Predecessors Application service provider? Software as a service(Saas))? Platform as a service(PaaS))? Grid computing? Utility computing? Computation Trends Virtualization application and infrastructure are independent Grid computing distributed computing where the supporting nodes are geographically distributed or cross administrative domains. Utility computing packaging computing resources as a metered service similar to a traditional public utility (such as electricity, water, natural gas, phone network, etc.) Software as a service pay as you go, service on demand 4

Slide 5

Cloud Computing A Convergence Cloud is a style of computing Use Internet technologies Virtual Scalable and elastic IT-related capabilities Efficient Flexible 5

Slide 6

Now and Future Traditional licensed software Expensive sedan with fixed price for basic+additional equipments, extended warranty cash up front Software as a service Leased car without being able to make significant change daily or monthly fixed charge Cloud computing Metered cab pay as you go, no maintenance costs Multi-tenancy More scalable, secure, reliable 6

Slide 7

Cloud Computing Examples: Telecom CaaS Compute as a Service AT&T CaaS, Verizon CasS Emphasis on utility, flexibility, layered approach to enhance security, workflow improvement CaaS, 2010 Chunghwa telecom What it says: At least 100GB storage service Reliable Low cost (pay as you use) Portability Scalability Backup and recovery 7

Slide 8

Cloud Computing Examples: The Giants Google Gmail, Google Docs, Google Talk, Google Canlendar, Google Gadget IBM Cloud Microsoft Software + service Yahoo Yahoo!Live, Yahoo!oneConnect, NewsGlobe Amazon Amazon Elastic Compute Cloud (Amazon EC2): a web service that provides resizable computation capacity in the cloud 8

Conclusions and Thoughts (1/3) One infrastructure, several needs Moving to cloud-based eHealth services is the future Health IT is increasing complexity Healthcare providers core activity is not to build and maintain IT expertise Shared infrastructures between several independent entities are necessary Different requirements, different needs, one cloud! Cloud-based service infrastructure must be open enough to handle the different requirement Customization of workflows is key The future is NOW! Few leading eHealth cloud infrastructure already exist! A large range of services is already available, from archiving to PACS and collaboration services 42
