Introduction to Cloud Computing

To understand Cloud Computing in the healthcare industry,we first must understand the fundamentals of cloudcomputing.


5/20

Introduction to Cloud Computing cont.

The expression the cloud has its roots in telephonyapplication in the early 1990s.

The expression came from that fact that during the infancyof the Internet, it used the telephone utilities dial-upsystem to work.

So the computing equipment that made this happen wassaid to be up there, somewhere in the clouds.

Originally, Cloud Computing was a vague term for a veryvague and distant future in which computing would occur ina few remote locations without the need for very muchhuman intervention. Infinite computing resources would beavailable for any need at costs approaching zero.

Today, the vast improvement in technology has made CloudComputing an reality.

It has allowed individual users and companies to accesscomputer services in the cloud, i.e., online banking, onlineshopping, GPS and mobile devices.

The National Institute of Standards and Technology (NIST)defines Cloud computing as model for enabling convenient,on-demand network access to a shared pool of configurablecomputing resources (e.g., networks, servers, storage,applications, and services) that can be rapidly provisionedand released with minimal management effort or serviceprovider interaction.


8/20


The basic value proposition of cloud computing is: buy only theresources you need to consume when you need them, and payaccordingly. For example, organizations can run applications in thecloud and pay for only what they use based on the number of virtualCPUs, available memory, storage and network utilization.

The cloud model can be used to run software, handle testing,expand storage, facilitate collaboration and more. In short, cloudenables infrastructure to be treated as a service. All of these

services offer improved agility and scalability, making users feel as ifthey have a virtual data center at their disposal.

Healthcare & Cloud Computing

With the enactment of the HITECH Act of 2009, thehealthcare industry is looking for ways to meet the digitalrecord requirements without a large increase in capitalexpenditures.


10/20

Advantages of Cloud Computing inHealthcare

Low costs

Cost may be reduced and capital expenditures are converted to operationalexpenditures.

No need for a physical data center infrastructure on site.

Demand less Information Technology support

Redundancy and Security

Data is managed off-site which makes it suitable for business continuityand disaster recovery.

Security is often better because vendors can spend more money,resources, and time on security. The HITECH Act of 2009 mandatesthat all healthcare vendors offering cloud computing must conform to

HIPAA Security standards.


11/20


Increase in Productivity

Allows providers to focus less on managing system integration andmore on delivering better care.

Allows physicians to collaborate and share information seamlesslywith other physicians and specialist over a secure Internetconnection.

Reduction in man-hours for looking for misplaced charts if patientdata is store in the cloud.


12/20


Accessibility

Enables physicians and other healthcare specialist to access patientdata and applications using a secure web browser regardless of theirlocation.

Can be accessed using different devices, i.e., laptop, or mobiledevices.

Information on one cloud is connected to bigger clouds


13/20

Cloud Computing Disadvantages inHealthcare

Costs

Use the comparison of buying verses leasing a car

Leasing seems more manageable than a large lump capital payment,however if you keep your car past the lease agreement, your total leasepayments are going to be more than if you just paid the lump capital

payment Same goes for paying for applications and data space in the cloud. The

total fees paid to a cloud provider may end up being more over anextended period than the cost of a just paying and owning the systemlocally.


14/20


Accessibility and Productivity

Patient data and other clinical practice information are onlyaccessible if your internet connection is working.

Internet service disruption would have a significant effect on officeproductivity.

Possible long lag-time on the internet during peak hours

Since the data is managed offsite, the vendor must have a standardmethod(s) of data recovery and backup, i.e., add additional datacenter, or regional redundancy


15/20


Long term vendor support

What happens if your vendor goes out of business ordiscontinues the application? (see page notes)

Can you get your patient data out? Will the patient chart/data be in a format that other

vendors can support and import?

If you had to print out the patient chart/data, will it be

in an easily understandable format?

Security - beaches are still major issue in Cloud Computing

July 16, 2009, Twitter company files leaked in Cloud Computingsecurity failure. Infosecurity.com

April 28, 20011, Amazon outage a valuable lesson in cloudsecurity. Networkworld.com

Consumers are worried about Insurance companies getting ahold of there information and discriminating based uponcurrent medical conditions.

They are also worried about the government or employergetting a hold of there information and exploiting it to thirdparty vendors.


17/20

Summary

Eventually most software applications and data storage used inhealthcare will be hosted in the cloud. In order for this to beaccomplished, the unresolved issues surroundingperformance, reliability and security that is needed for

EHR/EMR data intensive applications needs to be addressed.Currently, healthcare and technology providers are workingtogether to ensure that cloud computing is secure and meetsthe regulations stated in the HITECH Act of 2009 and HIPPA.

Once these concerns tackled, possibilities of the cloud areendless in the healthcare industry and for the strive to improvepatient care.
