JSON and Cloud Computing Vulnerabilities

cloud computing dangersOne of the benefits of browser focused computing is its platform independence: all you need is a good browser and an Internet connection, and you’re in business.

The technology that enables such convenience in many cases is AJAX. AJAX allows data to be loaded quickly and asynchronously, with no need for the user to refresh the page. AJAX even enables data to be loaded in the background without delaying page rendering, which greatly improves the user experience.

One problem with AJAX, however, comes with sites like Flicker and Twitter that provide RSS feeds. AJAX has issues when it comes to accessing that feed however. The RSS feed can be accessed only by the same domain it is hosted on.

In this particular case, JSON can save the day. AJAX powered sites can use JSON (JavaScript Object Notation) to access the data. JSON allows such sites to use a method called JSONP that uses a callback function to send the JSON data back to the domain. It’s this capability and the speed by which it is able to do this that makes JSON so incredibly useful.

The usefulness of JSON doesn’t come without its downside. That downside is security vulnerabilities. The security vulnerabilities of JSON usually come from poorly written code rather than a developers maliciousness. A eval() can render the system vulnerable to malicious code. The problem for the user is it isn’t always possible to know whether they are trusting their data to a site with a good implementation of the code.

It’s important to be knowledgeable of the potential security risks you take on a daily basis and to know cloud computing – or computing in your browser – has its dangers. This doesn’t make cloud computing a less valid form of computing. After all, every kind of computing has its own particular risks, however, knowing of the risks enables you to take the necessary precautions.

The troubling issue about JSON is that the security fix is at the hands of the developer, not the user.  The user may not even know a vulnerability exists until their security has been compromised.  Google is working on its own implementation of JSON called GSON which is about to released to the public. Hopefully this can address some of JSON’s security issues.

 

Will “Super Wi-Fi” Help the Cloud?

superwifiGoogle along with nine other companies were granted this week special administrative status for “white space” broadcast spectrum by the FCC. The spectrum was previously used as a buffer from television broadcast signals, but since TV has moved into the digital realm it is ripe for technological development.

One of the purposes would be to create a “super wi-fi” service with the spectrum because it has a long wavelength and thus could cover much more area than today’s standard wifi signals. It could perhaps create a national wifi service that could potentially be used to connect all sorts of devices.

The cloud is going to be integral to Chrome OS and that may be a problem according to GigaOM’s Sam Dean.

Chrome OS competitor Jolicloud will be releasing their first netbook in the UK very soon.

Google’s second official hardware offering, the Nexus S, briefly made an appearance on Best Buy’s website.

The Beta Channel of Chrome browser has been updated on all platforms with stability and UI fixes.

TechCrunch’s Michael Arrington is reporting that a Google engineer was recently offered $3.5 million to not defect to Facebook.

Chrome OS Early Adoption Debate is More About the Experience Than You Think

Posted on 05. Aug, 2010 by . 4 Comments

We’ve seen comments coming straight from Google that perhaps Chrome OS will only serve an early adopter market. Sure, we also once thought about that with Apple’s iPad, and look what happened there: in 2010 analysts projected at best 5 million would be sold, which has now been adjusted to 12 million sold.

I really think what has fueled the iPad’s success, and what will also help Chrome OS, is the downright anger towards the Windows operating system. While Windows 7 has been a moderate success according to the media, it’s still a crappy operating system, and one that is used by well over ninety percent of PCs.

Some may not enjoy my disregard for Windows, but rest assured I’ve been dealing with it for years and it’s simply no good. Can Microsoft improve it? They may be able to, but let’s remember we’re on version seven folks, and they should have just stuck with the principles of Windows XP rather than change it to look like an operating system that Apple makes.

It’s hard to suggest a comparison for adoption rates between Google’s Chrome OS strategy and that of the Nexus One, which is a reach since Google won’t be branding the hardware. Instead, it will be up to major manufacturers to create and market these products, much like the uber-successful Android model right now. While Google tried the Nexus One path, it didn’t take off. On to the next chapter.

Will it take time for Chrome OS to gain traction? Maybe. But then again, we also thought that about the iPad. It all depends on the quality of the user experience, and whether the cloud can hold up its end of the bargain.

Google Commits to 20 Years of Green Power Purchases

googleenergyresourcesThe Official Google blog posted really early this morning a release that talks about the company entering into a twenty year green power purchase agreement to buy energy from an Iowa wind farm called the NextEra Energy Resources Story County II. By buying this power at a set rate today for 114 megawatts over twenty years, the company puts a lot of commitment behind NextEra’s plans to expand its wind energy portfolio. It also gives Google more of what it is going to increasingly need: energy.

The second quarter saw Google double its spending on data centers – from $276 million in the first quarter to $476 million the previous. There’s no doubt that will the continued rollout of cloud computing that Google is going to need more data center infrastructure – and more power.

Consider that in the first quarter of 2008, Google spent $842 million on data center expenditures, and you can see how widely variable this spending is going to be. The price of energy fluctuates on a very high level, so whatever Google can do to stay ahead of the curve, it will do.

Chrome OS will be bringing everything to the cloud for users. That means more data is transferred from Google’s customized servers, and more power consumption on the back end. It appears that the information economy version of the industrial engine, the data center, and its ever growing use of energy will power the growth of this trend.
