Health It: Comparison Cloud Computing Together With Desktop Applications (Part One Of 3)

I simply responded to a comment posted to Linked-In at this link. The comment began:

Health attention information technology is moving from desktop application to complex multi-faceted Enterprise systems. The OS, wireless devices, in addition to databases are much to a greater extent than sophisticated than fifty-fifty a few years ago. Enterprise safety takes a science laid that is non readily available inwards much of the wellness attention industry. Staff HIT most probable volition non receive got the expertise to harden these systems. The needed skills real alongside system(s) in addition to network. As the HIE rolls out, safety volition decease to a greater extent than complex. But inwards maxim that, many non technical requirement tin hold upwardly covered today alongside written policies in addition to enforcement.

I replied:

Better yet ... Stick alongside desktop applications that commutation patient information via secure e-mail using innovative decentralized peer-to-peer cyberarchitectures. See, for example, /search?q=novel-way-to-exchange-patient-health

To which the commenter responded:

Stephen, Interesting but I come across desktop apps such every bit Microsoft Excel are giving agency to Cloud computing. Desktops app no longer brand fiscal feel from a maintenance standpoint.

H5N1 federated arrangement is a groovy agency to commutation information but nosotros volition receive got to come across what HITSP, (for one) comes upwardly with.

I in addition to therefore replied alongside the following:

While desktop apps are becoming Cloud enabled (which tin hold upwardly a goodness affair inwards certainly circumstance), I create non come across desktop apps ever beingness replaced past times the Cloud for many reasons. There are distinct pros in addition to cons of each depending on the province of affairs in addition to work case. For example, accessing in addition to processing information from local storage using local estimator resources (as opposed to the cloud) has many benefits, including the following:

• Since in that location are concerns virtually the safety of information stored inwards the Internet cloud [Reference1, Reference2, Reference3], people may experience to a greater extent than secure if they receive got consummate command over their private information (such every bit personal wellness information), which is stored inwards encrypted information files inwards their ain computers in addition to other computerized devices.
• Total damage of ownership is minimized since in that location is no postulate to rely on expensive key servers, databases, in addition to server administrators. Also, in that location are times when the cloud is to a greater extent than expensive than alternatives (Reference1, Reference2, Reference3).
• Performance is greatly increased when performing complex, intensive computations since all information processing is done rapidly in addition to easily using local estimator resources, rather than waiting for a strained key server, or paying for an expensive racks of servers. However, when massive computations from hugh centralized databases must hold upwardly done, for which a local PC is inadequate, cloud in addition to grid-cloud computing may serve an of import constituent (although grid computing solitary may surfice). [Reference]
• All the information tin hold upwardly accessed anywhere/anytime, fifty-fifty if in that location is no Internet or other network connections.
• Unlike communications requiring continuous connectivity, in that location is no loss of information when a network connectedness drops out (i.e., unexpected disconnection) [Reference]
• A node-to-node network [e.g., a mesh node network] is to a greater extent than robust. In web-based networks, a key server breakdown may crusade the entire network to nigh downwards in addition to forestall anyone from exchanging data. In the node network, however, a malfunction inwards ane or fifty-fifty many private computers may receive got piddling or no upshot on the network every bit a whole since performance nodes tin soundless communicate alongside each other. In other words, in that location is no unmarried signal of failure to disrupt in addition to entire network when a key server develops problems.
• Since copies of the encrypted information files tin hold upwardly stored inwards many unlike locations (i.e., widely distributed), information survivability is enhanced inwards the aspect upwardly of terrorism in addition to natural disasters.
• And next are key advantages in addition to disadvantages of spider web versus standalone applications:
• Web applications are easily accessibility because they tin hold upwardly easily accessed from whatever estimator or location that has Internet access. With a standalone, the estimator must receive got the application installed. On the other hand, in ane lawsuit the standalone application is installed, it is accessible anywhere/anytime, fifty-fifty when in that location is no adequate Internet connection; Web applications, however, typically rely on persistent in addition to unmanaged Internet connections, or else the information are inaccessible.
• Maintenance in addition to forced upgrades are lower because alongside spider web applications when a society must contend hundreds or thousands of desktop computers, although this has decease less of a job alongside improvement inwards automated desktop updates. On hosted systems, furthermore, users are at the mercy of the host; so, if an upgrade does non decease well, or the private user doesn't desire or postulate the novel features, the upgrade volition soundless decease forward.
• Over the life of the software use, spider web applications are typically significantly to a greater extent than expensive over fourth dimension because desktop applications are purchased outright in addition to in that location are rarely recurring fees for the software work (except for possible maintenance fees or fee based upgrades associated alongside them). Many corporate spider web applications, however, accuse users monthly service fees (i.e., "subscription fees") to operate the software. [Reference] 
• Web applications relying on the Internet to transfer data, rather than a using a computer's local difficult drive, may operate slower. The speed may every bit good vary depending on number of users accessing the application (i.e., network traffic). Standalone applications receive got no such constraints; the application volition operate every bit fast every bit the person's estimator mightiness allows.
• When using a spider web application that is hosted past times a 3rd party, privacy policies should hold upwardly inwards house to forestall that information from beingness used past times the spider web host. This is non an number alongside standalone applications.[Reference]
• Multiple desktop applications tin hold upwardly integrate in addition to used, enabling a model's functionality to hold upwardly enhanced past times other software programs. This cannot hold upwardly done securely using a web-browser.[Reference]
• "Because all computation is done on the estimator that the application is running [offline], the amount of information transmitted over the mesh is reduced…In the instance of spider web based application the information is passed dorsum in addition to forth betwixt the customer in addition to the server each fourth dimension a novel calculation is to hold upwardly done. If many clients are connected to the server at the same fourth dimension this leads to allot of processing on the server in addition to the mightiness of the clients is non used."[Reference]
• While standalone applications may hold upwardly the platform subject (e.g., tin only operate on Windows computers), it is possible to laid upwardly platform neutral applications that avoid this constraint.
