Lecture b

Cloud Computing

"Cloud computing is a model for enabling ubiquitous, 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.“ (NIST, 2011)

Health IT Workforce Curriculum Version 3.0/Spring 2012


Lecture b3

Distributed Computing• Sharing the processing workload between

connected computer systems• SETI@home

– examines radio telescope data for signs of intelligence using computers connected over the Internet

– volunteer computing resources



Lecture b4

Cloud Computing Characteristics

• On-demand self-service• Broad network access• Resource pooling• Rapid elasticity• Measured service



Lecture b5

Cloud Computing Service Models

• Cloud Software as a Service (SaaS)• Cloud Platform as a Service (PaaS)• Cloud Infrastructure as a Service (IaaS)



Lecture b6

Deployment Models

• Private cloud• Community cloud• Public cloud• Hybrid cloud



Lecture b7

Virtualization• Multiple virtual computer systems running on a

single physical system• Component of cloud computing• Not a new idea; IBM’s Virtual Machine

Facility/370 released in 1972• Each user appeared to have a dedicated system



Lecture b8

Hypervisor• Virtual systems do not have to be the same

operating system or instruction set as the physical hardware

• Virtual systems are managed on the physical system by a hypervisor

• The hypervisor emulates the instruction set of the virtual hardware

• Available through open-source software and commercial vendors



Lecture b9

Cloud Computing Issues• Access• Security



Lecture b10

Social Implications• Computers have changed the way people communicate

– E-mail– Instant messaging– VoIP– Video– SMS– Social networks– Local based services

• Personal health records• Privacy



Lecture b11

E-mail• Most individuals in the United States now have

an e-mail address• Initially limited to text• Multi-media capabilities added• Easy to “spoof” sender address• 90% of all e-mail is estimated to be spam• Rejected by ISPs or mail servers



Lecture b12

Instant Messaging• Initially used to communicate to computer

mainframe operators• Could communicate between users on same

system• Can now be used to send text between users

over global Internet



Lecture b13

Video and Voice-Over IP• Makes calls over the internet to another VoIP

phone• VoIP only phones available from commercial

vendors• Soft phones available which use computer

microphone and speakers• Commercial voice and video services, often at

no cost to users



Lecture b14

Short Message Service• Text messaging

– Shorthand language– Emoticons



Lecture b15

Social Networks• SixDegrees (1997)• Friendster (2002)• LinkedIn, MySpace (2003)• Facebook, Twitter (2006)



Lecture b16

Location Based Services• GPS in many mobile devices• Can identify local services• Can also provide information on an individual’s

location to others• Extends to social networking services



Lecture b17

Personal Health Records• May be stored on a personal computer• May be on personal storage device• Moving towards web-based services

– Microsoft HealthVault



Lecture b18

Privacy• Increasing on-line presence• Increases in customized content delivery• Individual reputation over time• The internet is forever• Privacy of medical records

– HHS breach list



Lecture b19

Ubiquitous ComputingComputers have become portable• Laptops since the 1990s• Netbooks since the early 2000s• Personal Digital Assistants (PDAs)

Computers are everywhere• Cars• TVs• Home appliancesHealth IT Workforce Curriculum Version 3.0/Spring 2012


Lecture b20

Personal Area Networks (PANs)• Bluetooth• Wireless connection• 1 to 100 meter range connection radius• Used for mice, keyboards, headsets, etc.



Lecture b21

Implications For Healthcare• Telemedicine

– Brings the doctor to the patient– Uses

• Internet • Integrated audio and video capabilities

• Clinical decision support• Elder care monitoring• Individualized health care



Lecture b22

Risks of Technology in Healthcare• Side effects of using new technology – example:

radiology• Potential for more false positive test results• Higher healthcare costs• Intended and unintended consequences of

technology implementations



Lecture b

The Future of ComputingSummary – Lecture b

• Cloud computing• Social implications• Ubiquitous computing• Affect on healthcare systems



Lecture b

The Future of ComputingSummary

• Decrease in system size and increase in system performance

• Increasing options for system control• Movement to network applications• Changes in our society• Pervasiveness of computer technology• Futures:

– Wearable systems?– Elimination of the keyboard?– Societal changes?– Changes in home health care?
