Ubiquitous computing with Cloud Services
By Ogunleye George
Cloud computing refers to outsourcing data once stored on privately owned computers; here’s now the most up to date IT trend within the business world, their explanation for tapping into cloud power boils right down to cost-cutting and convenience.
This allows companies to shed expenses on IT infrastructures by reducing the quantity of hardware and software they must purchase and maintain to process and store information.
The basic tenet of cloud computing is that the responsibility of maintaining the software, database etc isn’t any longer within the hands of the user or business owner, but is relegated to a 3rd-party.
The concept of Cloud computing further strengthens the assumption of Ubiquitous computing enabling an actual-time global sensing, informational retrieval, and multimodal interaction with the user and enhanced visualization capabilities. In effect, gives extremely new and futuristic abilities for user to examine and engage with at any time and from anywhere.
However, potential security threats to virtualized computing environments are complex as most client of cloud computing don’t know who’s managing the computers with their information; no idea of where their data are; no idea what protections may or is probably not in place to ensure their information isn’t stolen or disclosed or that it doesn’t accidentally disappear.
Lately, cloud-based services had been taking a little bit a beating. Sony’s PlayStation Network got hacked and was offline for greater than six weeks. On April 21st Amazon’s EC2 cloud-based platform fell over, since many tech sites use EC2, they’d the knock-on effect of taking down services equivalent to Reddit (social news website), FourSquare (a location-based social networking website for mobile devices) and Quora. Few days ago, Visa and MasterCard warned banks of a potentially massive breach of payment card information which can affect over 10million customers.
The large contentious question is thus: should very sensitive HR data reside on the web?
Knowing that these firms are fully attentive to the legal implications of losing customer’s; deep facts favours wise use of keeping data on vendors’ servers operating on the web or “in the cloud,” and never on a company’s computers but truth be informed, it is a very risky practice, because it sends a “store your data at your personal risk” message across.
Cloud hosting takes up less space thereby saving companies cost of implementing and maintaining expensive technologies. Software-as-a-service (SAAS) or in other words, “cloud computing” offers “renting” as opposed to buying of software to accommodate information similar to payroll, benefits or recruiting data; this conveniently lifts off IT maintenance burdens.
Cloud computing makes an IT investment more efficient, flexible and faster and allows access to data anytime, anywhere, anywhere and with any electronic device.
Having ubiquitous access to that data make that data more at risk of theft and exposes it to threats.
Cloud storage solution that is dependent upon a password to access your data will have its passwords hacked. However, you should choose a password that’s difficult to hack with dictionary attacks, and likewise regular change of password help reduce the possibilities of success from brute force attacks.
Data en path to a cloud server could be captured; however, most storage services will encrypt the info on transit, making it impossible to read despite the fact that the file is captured. In case your cloud storage works through an online app, search for “https” rather than “http” in front of the URL to your browser’s address bar. That extra “s” indicates the shape is using secure HTTP.
If you may have a standalone cloud storage app installed in your computer, check to make sure that app uses some kind of encryption for its Internet exchanges.
Cloud service models include:
Infrastructure as a Service (IaaS): looks after support operations by providing model where client services and gear are housing, ran and maintained.
Platform as a Service (PaaS): provides computational resources throughout the platform which includes Operating System. PaaS is built upon the principals of Infrastructure as a Service by providing an atmosphere where applications may well be built and deployed in a safe, rapid and fine manner. This eliminates the hardware dependency and capacity concerns.
Software as a Service (SaaS) is the most effective sort of cloud computing. It covers the implementation of specific business functions, customized business applications, etc. It reduces the hardware and licensing cost..
When computing is outsourced, control of safety features could also be relinquished; thus eradicating the responsibility of the business owner. This isn’t a viable ethical practice especially for financial institutes which more often than not are the best patronisers of cloud computing.
