Why Is Cloud Computing So Important?

Cloud computing has a lot of hype surrounding it. More than a few observers have wondered what is so important about this new internet phenomenon. The truth is cloud computing is leading to a rethinking of the internet’s capability. Cloud computing promises to completely delocalise computing power and technology. Users will be able to access and manipulate files, images, videos and other data remotely. Cloud computing promises the ability to keep networks and mobile devices synchronised at all times.

Infrastructure

A bank of sophisticated computers host operating systems and data for hundreds, if not thousands, of customers. internet search engine giant Google pioneered the use of data centers to store clients’ personal data safely. The same principle is being extended to cloud computing. Huge data centers will act as remote desktop computers. These centers will be able to store every file a user would need. All the user needs is a counterpart machine that can be as small as a conventional laptop with much less weight. These so-called “netbooks” serve only to connect the user to the internet so he can access his files.

A cloud computing network

An example of how cloud computing works – every device synchronises with the cloud, meaning that your data can be accessed anywhere!

A single data center can offer multiple services and applications. Theoretically, a cloud computing system could perform almost any function or task the user desires. In a typical system, each application will have its own dedicated server combined with multiple iterations to create redundancy and prevent sudden malfunctions. The whole center is managed by a central server that constantly monitors the traffic and load volumes. Balancing the differences between machines, it seeks to maintain the harmony of the system and prevent crashes.

Business Advantages

The advent of cloud computing is actually forcing businesses to change their strategies. Previously, hiring a new employee meant providing him with a desk, computer equipment and various other hardware or software. Cloud computing allows them to reduce these capital expenditures significantly. Now all an employee needs is a computer with an internet connection to access his work data. Desks and office equipment may still be necessary, but the investment in computer hardware can be outsourced to cloud computing companies.

The hardware and software demands on the business’s side decrease dramatically. Labor costs per individual employees go down, enabling a company to hire more workers. Productivity increases, raising the efficiency and profits of the business.

Concerns

The primary reason why cloud computing is getting so much attention is its effect on business strategies. The sheer cost pressure alone is forcing industry after industry to adapt to the new reality. The advantages notwithstanding, several valid concerns about cloud computing exist, namely having to do with privacy and security.

Business owners and executives may hesitate to turn over their sensitive data to a third-party system with good reason. Losing access to their own data or having it compromised is unacceptable in a ruthlessly competitive private sector. One major argument against this fear is the fact that cloud computing companies survive based on their reputations. This gives them a huge incentive not to lose their clients data or compromise accessibility. Despite the power of this incentive, regulations may still be required to ensure safety.

As for privacy, the obvious concern is the connection between the user’s computer and the cloud system. Privacy could easily be compromised by unscrupulous individuals who could access personal information like credit card numbers. A solution to this problem is to use authentication and encryption like regular secure connections.

These practical concerns are somewhat overshadowed by a number of philosophical and legal questions. For instance, who owns the data stored by the cloud computing system? While it is held in the client’s name, a case could conceivably be made that the cloud computing system is the actual owner and therefore has a right to it. These technicalities are still under debate, and no resolution has yet been achieved.

Conclusion

Cloud computing holds great promise for upending things as they are currently done in the business world. The practical effects on information technology jobs will likely be profound. These and other challenges must be met because cloud computing will continue to change the nature of the internet.

See Anyone You Know? Face Recognition Comes Of Age

The National Academy of Sciences are about to publish an article in their proceedings entitled ‘Privacy In The Age Of Augmented Reality’, co-authored by Alessandro Acquisiti, Ralph Gross and Fred Stuzman. It is about developments in face recognition software.
How 2D facial scanners record identitiesTo use the authors’ words the document

“investigate(s) the feasibility of combining publicly available Web 2.0 data with off-the-shelf face recognition software for the purpose of large-scale, automated individual re-identification.”

They are also working on an app that can do it all from your phone! See the FAQ section here for more information. The article reports a series of experiments conducted over the last year or so during which the researchers try to identify a person from their photo using an over the counter face recognition software using information that is freely available over the internet.

The results are interesting. The experiments are as follows:
Students walking through the university campus were asked if their photo could be taken and to complete a questionnaire. As they were answering the questions the computation task was carried out, looking for a picture match on Facebook and requiring only seconds. In this case more than 30% of the students were immediately traced.

Because the faces were the same but the photos taken from different angles, humans had to decide which of the possible matches were the most appropriate, but that is not always the case. Some photos are replicated and therefore the computer can give a 100% guarantee that the match is correct.

For example in another experiment the researchers used an online dating agency that provided anonymous photos. In this case they could match names to the photos in about 10% of cases. In several cases the same photo had been used on different sites.

In a third experiment the knowledge gained was used to search for further private information, all freely available on the web, such as details of sexual preference, date and place of birth and this information even allowed them to generate the first five figures of the individual’s US social security number.

So it seems that we can draw a simple conclusion here, either now or in the very near future, as these technologies are improved and made freely available, anybody will be able to recognize anybody they see on the street, identify them through an app in their telephone, and find out about their interests and other personal information, if they have ever posted (or had posted for them) a photo of themselves on the internet.

Barcoding – a history and the future

Many youngsters these days are not aware of how recent barcoding technology actually is. In the 1970’s a mere forty odd years ago, it would have been a rarity to see a barcode – anywhere.

Before the barcode, retail was not nearly as efficient as it currently is. Often, till assistants would have to memorise the price of every product in the shop, or products would be individually priced. Furthermore, it was almost impossible to keep tabs on stock levels in real time.

Barcodes revolutionised industry.

Barcoding in retail

Now when you pick an item and take it to the till, a barcode is scanned. The till is linked to a central database where all the barcodes for that shop (or even the entire shop chain) are stored. Information on the price of the product, the stock of the product and usually a description and or image of the product, is all stored in relation to the barcode. Upon scanning, the price is retrieved from the database and one unit is deducted form the shops stock list.

Barcoding makes it easy to increase prices and to reorder stock, that way if something has high demand and is selling fast, more orders can (sometimes electronically) placed and the store can consider raising the price.

Barcoding in car production

Barcodes are also used in many other areas, one example being car production. In car production, each car will be given a barcode. That barcode will often contain information such as the type of car that is to be made, how the car is to be styled, what colour the car is to be pained etc.

Parts that have been made for that car will often also be associated with the same barcode, to ensure that every bit gets to the right car.

The classic barcode is the one with lots of vertical lines, each of different thickness. Below is an example of a classic barcode.

A Random Classic BarcodeDespite the classic barcodes uses, many people believe that the future of barcoding lies with QR codes.

QR Codes

QR codes are like barcodes in that they are all unique, however the image itself can actually store some information. QR codes are common in Japan, however they are slowly making their way westward, and and not uncommon in Europe now.

If you go to your fridge or a cupboard and pick up half a dozen items, the chances are at least one of them will have a QR code. I found one on some cheese the other day 🙂

QR Code‘ stands for ‘Quick Response Code‘ as they can quickly retrieve information, just by decoding the pixels in the QR code/image.

QR Codes are basically a code (durr) containing some form of information, be it text, a URL, etc. When you run the image through a QR decoder, it will work out what data is stored in the image.

Confused? Okay, let me give you an example. Below is a QR code image. If run the image through a smart phone QR decoder or an online QR decoder, you should find that it contains the information ‘www.TechnologyBloggers.org’. Why not try it out?

Technology Bloggers QR Code

When decoded this QR Code says 'www.TechnologyBloggers.org'


That information is stored in the actual image, and there is no need for you to connect to a database. That is why many people believe that they are the future of barcoding, as a barcode stores no actual data in the lines, just a reference to a counterpart on a database.

QR codes could store the name of a product and the price on that actual barcode image – although to deduct stock, they would need to be linked into the stock database.

In many countries, QR codes are being used in advertisements, and in some places, that are being used as the actual advert. This is to try and encourage people to decode the image and find out what it means.

So what do you think, are QR codes the future of barcoding? Could they both coexist, or will one emerge on top? What is your opinion of QR codes?

Over to you 🙂
