Technology Sector BREAKING DOWN 'Cloud Computing' In its essence, cloud computing is the idea of taking all the heavy lifting involved in crunching and processing data away from the device you carry around, or sit and work at, and moving that work to huge computer clusters far away in cyberspace.

Different Types of Cloud Computing Cloud computing is not a single piece of technology, like a microchip or a cell phone. Rather, it's a system, primarily comprised of three services: SaaS is expected to experience the fastest growth, followed by IaaS.

Software as a Service SaaS: SaaS involves the licensure of a software application to customers. Licenses are typically provided through a pay-as-you-go model Information technology cloud computing on-demand. Infrastructure as a Service IaaS: Infrastructure as a service involves a method for delivering everything from operating systems to servers and storage through IP-based connectivity as part of an on-demand service.

Clients can avoid the need to purchase software or servers, and instead procure these resources in an outsourcedon-demand service. Platform as a Service PaaS: Of the three layers of cloud-based computing, PaaS is considered the most complex.

PaaS shares some similarities with SaaS, the primary difference being that instead of delivering software online, it is actually a platform for creating software that is delivered via the internet.

Thanks to cloud-computing services, users can check their email on any computer and even store files using services such as Dropbox and Google Drive.

Cloud-computing services also make it possible for users to back up their music, files and photos, ensuring that those files are immediately available in the event of a hard drive crash.

Cloud computing offers big businesses some serious cost-saving potential.


Before the cloud became a viable alternative, companies were required to purchase, construct and maintain costly information management technology and infrastructure. Now, instead of investing millions in huge server centers and intricate, global IT departments that require constant upgrades, a firm can use "lite" versions of workstations with lightning fast internet connections, and the workers will interact with the cloud online to create presentations, spreadsheets and interact with company software.

Individuals find that when they upload photos, documents, and videos to the cloud and then retrieve them at their convenience, it saves storage space on their desk tops or laptops.

Additionally, the cloud-like structure allows users to upgrade software more quickly — because software companies can offer their products via the web rather than through more traditional, tangible methods involving discs or flash drives.

InAdobe Systems announced all subsequent versions of Photoshop, as well as other components of its Creative Suite, would only be available through an internet-based subscription.

This allows users to download new versions and fixes to their programs easily. Disadvantages of Cloud Computing With all of the speed, efficiencies and innovations of cloud computing come risks. Initially, security was seen as a detractor from using the cloud, especially when it came to sensitive medical records and financial information.

While regulations are forcing cloud computing services to shore up their security and compliance measures, it remains an ongoing issue.

Media headlines are constantly screaming about data breaches at this or that company, in which sensitive information has made its way into the hands of malicious hackers who may delete, manipulate or otherwise exploit the data though, according to some reports, most of the data breeches have been with on-site systems, not those in the cloud.

Encryption protects vital information, but if the encryption key is lost, the data disappears.

Servers maintained by cloud computing companies can fall victim to a natural disasters, internal bugs and power outages, too. And unfortunately, the geographical reach of cloud computing cuts both ways: A blackout in California could paralyze users In New York; a firm in Texas could lose its data if something causes its Maine-based provider to crash.
